Cummins Power Generation, Minneapolis, Minn., has developed new generator sets on both the small and large end of its gen-set range, along with new switchgear for emergency and standby power applications.
The new 150 kW model GGLB spark-ignited natural gas gen-set is designed to provide full-rated standby power for backup and emergency power applications. The new generator set features a heavy-duty GM 8.1 L four-cycle natural gas engine that is torque matched to a high-capacity Newage ac alternator for handling motor starting loads. An electronic governor provides precise frequency regulation for powering sensitive loads and the unit also accepts 100% of the nameplate standby-rated load in one step in compliance with NFPA 110, Level 1, the company said.
"The new 150 kW model GGLB spark-ignited generator set is both user-friendly and environment-friendly," said Colette Weiser, market manager for Commercial Standby Generator Sets, Cummins Power Generation. "The basic control system is easy to operate and includes system protection features, digital engine speed control and transfer switch compatibility. The industrial, spark-ignited V-8 engine burns clean natural gas for exceptionally low exhaust emissions." A wide range of options and accessories is available with the generator set to allow configuration for specific onsite power applications. The optional PowerCommand 2100 generator set control adds microprocessor-based features such as remote start/stop, integrated voltage regulation, alarm and status message display, output metering and auto-shutdown at fault protection for high reliability.
Several alternator sizes offer selectable motor-starting capability with low reactance, the company said. Available permanent magnet generator excitation delivers enhanced motor-starting and precise voltage regulation for nonlinear loads such as variable speed motor controls and UPS systems. The standard cooling system allows full-rated load operation up to 50[degrees]C ambient air temperature. Available weather-protective and sound attenuated enclosures permit installations at outdoor and noise-sensitive sites.
On the larger end, Cummins Power Generation has introduced a new low-BTU generator set series specifically designed to run on the dilute methane gas mixture produced by natural decay in landfills, sewage digesters or methane emitted from coal seams. The new GQ series generator sets produce a continuous 1570 kW (50 Hz) or 1750 kW (50 and 60 Hz) running on landfill or digester gas containing very low thermal energy, while producing low exhaust emissions. Multiple units can be paralleled for higher power production at larger landfill sites.
"Industry studies indicate that, globally, landfills represent an immense untapped energy resource," said Trevor Passmore, general manager for Energy Solutions, Cummins Power Generation. "In North America alone, candidate landfills can produce enough methane gas to support a total generating capacity of approximately 1500 MW. Currently, much of this potential energy is being flared off or vented into the atmosphere. This new generator set will provide landfill operators, utilities and independent power producers with a proven generating solution to make use of this energy resource. In addition, since methane gas released to the atmosphere has about 20 times the greenhouse effect of carbon dioxide and hence global warming potential, burning methane in a generator set can reduce its environmental impact by a factor of about 20."

New technology won't put freeze on fluids
Improving technology in vehicle manufacturing and in maintenance products to keep cars running better and longer is a double-edged sword for automotive chemical suppliers. Extended-life formulations in categories such as antifreeze, and the debut of lifetime-warranted transmissions in vehicles are shrinking the market for fluids and additives, presenting challenges for suppliers and retailers. On the plus side, these new products carry higher retail prices and margins.
As the market shifts toward longer-life products, suppliers are going along, promoting these less frequently purchased products while exploring new growth segments, such as diesel additives and products targeting the sport performance market.
"The general trend in fluids is to move closer and closer to a fill-for-life standard," said Larry Beaver, vp of technology at Radiator Specialty Company. "The day will come when there are fewer and fewer fluids to put in."
While this trend would seemingly panic a company such as RSC, which makes oil and fuel additives, brake, power steering and transmission fluids, and engine cleaners under the brands Solder SeaVGunk and Engine Brite, the company has responded proactively by focusing on products geared toward older vehicles. A new line of additives and fluids will debut this fall for older cars with 50,000 or more miles. Also in the works is a line of diesel additives related to a small but growing segment of diesel vehicles now coming to market, such as some Volkswagen models. The pattern of declining sales continued last year in functional fluid categories, according the to the Automotive Aftermarket Industry Association (AAIA). Sales of transmission, brake and power steering fluids all declined at the top automotive aftermarket chains, according to AAIA, while fuel and oil additives fared slightly better, showing slight growth. Transmission and diesel additives were up by more than 30%.
As for the largest revenue generator in chemicals--antifreeze--sales in that category declined 5.5% at the top auto chains. Again, better-performing products are leading to less purchase frequency of antifreeze, while weather also was a factor.
Antifreeze formulations specific to certain makes of vehicles began emerging in the mid-1990s. While at least five different colors/formulations are now on the market, depending on the make of cal, the latest innovation in antifreeze is a universal formula that works with all the newer models. Old World Industries launched its Peak Global extended-life antifreeze and coolant last fall, and now Prestone has followed suit. These universal formulas are expected to eventually replace the make-specific products and reduce retailers' SKU counts. Both provide a five-year, 150,000-mile limited warranty with a flush and fill.
"Retail customers were becoming overwhelmed by the numerous varieties of antifreeze/coolant they were carrying to meet consumer needs, which led to higher inventory costs and lower returns on their investments," said John King, Prestone product manager.
With the confusing category driving many consumers to service providers to check and fill antifreeze, these new universal formulas may revive DIY coolant sales.
"We wanted to make it easy and simplify the situation," said Jeff Stauffer, vp of marketing at Old World Industries. "It also is a benefit to us in terms of focusing and marketing one brand that we can put a lot of emphasis behind."
These new offerings in Peak and Prestone brands are a step-up in price to the traditional green ethylene glycol-based antifreeze used for older models of vehicles. For that reason, most retailers will offer a good/better/best selection, including make-specific antifreeze products such as Dex-cool for General Motors cars. Stauffer expects universal antifreeze will one day replace make-specific products.
Demand for premixed antifreeze is another factor reshaping the category, considering 70% of antifreeze sold is used for topping off rather than a complete flush and fill. Most companies make both concentrate and premixed antifreeze, with the ready-to-use segment growing to about 30% of sales, according to Stauffer.
Another niche segment is low-toxicity antifreeze, such as Old World's Sierra and Prestone's LowTox brands. These propylene glycol-based products appeal to those concerned about poisoning of pets or children from regular antifreeze.
"It's nowhere near a huge piece of the market, but it has its place. It's a niche offering," said Stauffer.

Obscuration
Smoke and other obscurants have been used in wars dating back to the ancient Greeks. On today's battlefield, smoke can counter new generations of smart weapons. Smoke is used as camouflage, as blinding smoke laid directly on enemy positions and as a decoy to confuse and mislead enemy forces. These basic smoke applications are used to increase survivability, buy maneuver time for the attacker and protect forward-assembly areas and high-priority rear areas for the defense.
Smoke particles scatter or absorb radiant energy used by troops and smart weapons for target acquisition and for weapon guidance and control. Smart weapon sensors operate in three main parts of the electromagnetic spectrum: visible, near-, mid-and far-infrared wavelengths, and millimeter wavelengths. The most effective scattering smokes are aerosols that are the same size as the operating wavelengths of the sensor to be defeated. The best smoke for the visible spectrum may be transparent in the far-infrared area. The entire chain of electro-optical, infrared and millimeter-wave devices linking a smart weapon to a target is susceptible to smoke and other obscurants. In addition to absorbing light, some smokes emit heat, which can cover or clutter the thermal images of targets.
The reflection of laser or radar beams from smoke clouds can produce false targeting information for smart weapons, which can be blinded and defeated by smoke. Battlefield obscurants allow combatants to take advantage of technology overmatch. In Operation Desert Storm, U.S. ground forces used infrared-viewer technology at night to achieve dramatic results.
The Army uses several models of smoke-generation systems, including: the M56 Coyote, the M58 Wolf, the M157A2 Lynx and the M1059/ M1059A3 Lynx. In addition, the M6 countermeasure discharger provides self-screening protection to individual combat vehicles.
The M56 Coyote Smoke-Generation System (SGS) provides large-area obscuration in the visual and infrared spectra. It is a Humvee-mounted, large-area, smoke-generator system. In addition to providing enhanced spectrum coverage, the M56 system provides smoke generators with a new wheeled-vehicle platform. The system is mounted on the new expanded-capacity M1113 Humvee and provides greater payload capacity and higher mobility for supporting smoke units.
Six M56 Coyotes form a smoke platoon. They support light and airborne maneuver units by disseminating smoke on the move or from stationary positions to defeat enemy sensors and smart munitions, such as tank thermal sights, guided munitions, directed energy weapons and other systems operating in the visible through far-infrared regions of the electromagnetic spectrum. The system is modular and uses a gas turbine engine to disseminate obscurants. The visual screening module is capable of vaporizing fog oil at a rate equal to the M157 smoke generator for up to 90 minutes. The infrared screening module can disseminate particulate material to provide 30 minutes of screening. M56 program planners cite the expanding global use of infrared targeting and sighting devices for prompting development of the M56 Coyote, the Army's first large-area smoke system capable of generating visible and infrared blocking screens.
The M56 Coyote was type-classified "standard" in September 1994 and was followed by an initial production contract award for 296 systems in March 1995. First-article and production verification testing were successfully completed in September 1996. By the end of February 2000, 231 systems had been fielded to U.S. Army Training and Doctrine Command (TRADOC), U.S. Army Forces Command (FORSCOM) and U.S. Army Reserve Command (USARC). Fielding continues to FORSCOM and USARC with a follow-on six-year contract.
A materiel change program to add a millimeter-wave module began in FY 2001. This program will provide extended spectral coverage to defeat threat weapon systems operating in the millimeter regions of the electromagnetic spectrum.
The fielding of new M56 Coyotes pushed older M157 SGSs down to lower priority units. The last chemical unit with the aging M3A4 smoke-generation systems received M56 Coyotes in the first quarter of FY 2002.
The M58 Wolf Smoke-Generation System places the capabilities of the M56 on a derivative of the tracked M113 armored personnel family. In addition to its current multispectral obscurant screening capabilities, planned materiel changes will allow the addition of a millimeter-wave (MMW) obscuration module, providing the capability to counter the threat arising from the wide proliferation of advanced visual and infrared sensors and future MMW sensorsPower Modules feature NEBS-compliant design
Rated at 1.6-2.3 kW, POWERCACHE[R] ultracapacitor-based, 48 V backup power modules provide maintenance-free alternative to batteries for short-term bridge power in UPS systems. Modules stay fully charged and recharge in seconds in case there are multiple grid power interruptions. Rack-mount units are suited for telecommunications, industrial, and medical applications.

POWERCACHE[R] Products Feature NEBS-Compliant Design and Construction, Provide Lower-Maintenance And Space-Saving Alternative to Batteries for Short-Term 'Bridge' Power
SAN DIEGO, Calif. -- Maxwell Technologies, Inc. (Nasdaq: MXWL) announced today that it has introduced two POWERCACHE[R] ultracapacitor-based backup power modules that provide a space-saving, maintenance-free alternative to batteries for short-term "bridge" power in uninterruptible power supply (UPS) systems for telecommunications, industrial and medical applications.
Robert Tressler, Maxwell's vice president of sales and marketing, said that the new 48-volt rack-mount modules, rated at 1.6 and 2.3 kW, are designed and constructed to comply with Network Equipment Building System (NEBS) standards required for telecommunications installations.
"Mission-critical facilities, such as wireless telecommunications base stations, data centers, automated factories and hospitals rely on UPS systems to avoid downtime in the event of power interruptions," Tressler said. "The batteries that currently are used in most of these systems are large and heavy, require regular maintenance and replacement, and are difficult to monitor in terms of state-of-charge. For those reasons, many end-users are looking for more reliable, more compact, lower maintenance alternatives, which is where Maxwell's POWERCACHE products come in."
Tressler said that Maxwell has been collaborating for some time with UPS system integrators, fuel cell and other backup power generator manufacturers to integrate its ultracapacitor-based bridge power systems with long-term backup power sources.
"Fuel cells, diesel generators and micro-turbines all take from a few seconds to a minute to start up and reach their full output, so UPS systems in which they are the primary backup power source all require a complementary short-term source that is instantly available," Tressler explained. "Our POWERCACHE modules stay fully charged and recharge in seconds in case there are multiple grid power interruptions. They also operate reliably for the life of the system with zero maintenance."
Tressler said that telecommunications industry data indicates that the global opportunity for these modules, each of which supports one rack of equipment, totals more than 2.5 million unitsThursday, December 14, 2006
Hatz, Robin Subaru to cooperate on small diesels
German industrial diesel builder Motorenfabrik Hatz GmbH and Fuji Heavy Industries Ltd. (FHI) d Japan have signed a cooperation agreement under which Hatz will supply up to 20,000 single-cylinder engines per year to Fuji's small engine subsidiary, Robin Subaru. At 1.2 million engines per year, Robin Subaru is considered to be among the top five manufacturers of industrial engines worldwide.
The background to the cooperation is the strategic decision by Robin Subaru to concentrate on its core business of building small industrial gasoline engines and packaging its own pump and generator sets. As a result, the company will discontinue production of its own DY series diesels and replace them in its sales program with the Hatz B Series single-cylinder engines. By this change, urgently needed capacity in both production facilities and the development of emissions-compliant gasoline engines will be freed up in Japan, Robin Subaru reported.
The project was won against European competition, noted Horst Dekena, Hatz managing director. "Undoubtedly, the perceived high quality of our products was a decisive factor, and it was a very positive experience to confirm that we can still be extremely competitive in Far Eastern markets with German built small diesels," he said. "Robin Subaru is also very impressed with our well-established, dense network of sales and service outlets in Europe, as well as our excellent contacts to the European construction equipment industryFor our part, we see the cooperation as a unique opportunity to benefit from unlimited access to Robin Subaru's excellent infrastructure in Southeast Asia."
Dekena also considered the new cooperation a further step in diversifying the company's offering and enhancing its position. "Over the past years we have built up a considerable presence in the supply of high-end connecting rods to the engine industry," Dekena said. "We count a number of leading European car manufacturers among our customer base.
"Now, the cooperation with Robin Subaru will lead to a significant extension of engine production at our works in Ruhstorf an der Rott, near Passau. This will lead both to a welcome reduction in our cost base as well as securing existing jobs and creating new jobs in the Lower Bavaria region."
Hatz feels the new collaboration fully vindicates its decision to develop the B Series diesels, whose smaller versions took the company for the first time into the applications of very low displacement single-cylinder diesels.
The engines concerned are the 1B20, 1B30 and 1B40 single-cylinder diesels. With displacements of 232 cc (bore 69 x stroke 62 mm) and 321 cc (bore 77 x stroke 69 mm) and 462 cc cover a power range of approximately 4 to 10.3 hp at rated speeds up to 3600 rpm. As well as standard horizontal crankshaft versions, Hatz B Series engines are also offered in vertical crankshaft (V suffix) versions, well suited to certain types of construction, agricultural and horticultural equipment. They are also designed to operate at severe tilt angles--Hatz quotes 30[degrees] from the horizontal in any direction.
All the models in the Hatz B Series meet the applicable EU and U.S. EPA emissions standards and are also scheduled to meet the voluntary emission control guidelines set forth by the Japan Land Engine Manufacturers' Association, which are slated to take effect in 2006.
Typical applications for the engines include slitters, vibrators, tampers, high pressure cleaners and generator sets on the construction equipment side and self propelled mowers, water pumps, soil and snow tillers and small market gardening and municipal equipment on the agricultural/horticultural side.
The agreement between FHI and Hatz grants FHI exclusive rights to market the Hatz B series engines only under the Robin Subaru brand name and other single- and multi-cylinder diesel engines manufactured by Hatz in Japan and Asia. This arrangement is expected to strengthen FHI's diesel engine lineup for a wider variety of industrial machinery customers, as well as those in the construction trades, and enable FHI's diesel model lineup to complement its wide range of gasoline models.

Report on quality changes for 2005 model vehicles
The value of quality changes for a sample of 13 model-year 2005 domestic passenger cars included in the Producer Price Index (PPI) for October averaged $283.12, according to estimates by the Bureau of Labor Statistics (BLS) of the U.S. Department of Labor. This change represents 73.8 percent of the average $383.86 increase in manufacturers' invoice prices for this year's models compared with last year's models.
The retail equivalent value of these quality changes averaged $310.50, representing 74.3 percent of the average $417.81 over-the-year increase in manufacturers' suggested list prices.
The $310.50 estimated retail value of the quality changes includes:
* $193.11 for federally mandated and nonmandated safety improvements, such as changes to brake and airbag systems
* $117.39 for other quality changes, such as emission improvements, changes in audio systems, and changes in levels of standard or optional equipment The value of quality changes for a sample of 18 model-year 2005 domestic light trucks included in the PPI for October averaged $306.26. This change represents 75.7 percent of the average $404.35 increase in manufacturers' invoice prices for this year's models compared with last year's models.
The retail equivalent value of quality changes for domestic light trucks averaged $345.38, representing 75.2 percent of the average $459.28 over-the-year increase in manufacturers' suggested list prices.
The $345.38 estimated retail value of the quality changes includes:

Almost as bad as an electrical fire aboard an ETOPS airplane
Fire in a submarine under the water has obvious parallels to fire in an ETOPS (extended range operations) airplane flying high above the water and distant from a suitable airfield. In both situations, the fire has to be fought "in place" until the airplane can land or the submarine rise to the surface. The case at hand involves the Oct. 4 electrical fire on board the Canadian submarine HMCS Chicoutimi off the west coast of Ireland. The submersible, previously operated by Britain's Royal Navy as HMS Upholder, is a 30-year-old dieselelectric long-range patrol submarine. Details are sketchy, but think of fire aboard aircraft in the context of this accident:
* Two electrical fires broke out while the vessel was preparing to submerge, causing extensive damage to electrical cabling. Huge sparks erupted from an electrical display panel near the control room. The first and major fire burned on both the first and second decks. (ASW note: one account has the sub submerged when the fire broke out, forcing it to surface in 30-knot surface winds and huge swells to blow smoke.)The second fire was in, or very close to, the boat's oxygen generator plant.
* The entire submarine was filled quickly with smoke. The captain said the smoke was so thick a flashlight shining could not be seen more than six inches away.
* Nine of the 57 crewmembers suffered smoke inhalation. Three of the men were so disabled by smoke that they were evacuated by helicopter. Lt. Chris Saunders, a combat systems engineer, died after being evacuated by helicopter to a hospital on shore.
* Propulsion power was lost.
* Ship-to-shore communications were lost after key electrical cables were knocked out. An officer used a battery-powered portable satellite phone to send a Mayday.
* The sub was left with the starboard diesel running to provide ventilation, lights and short-range communications.
* A half-dozen cell-phones were later passed on board from a nearby tug so that crewmen could call loved ones ashore.
* A separate inquiry is under way into the failure of the breathing apparatus to protect those killed and injured from toxic smoke and gas.
* A similar fire occurred in sister sub HMCS Windsor last spring, also involving electrical cables that ran past the commander's cabin.
For aviation and ETOPS, note the limited number of portable fire extinguishers in a typical aircraft cabin. Note that the fire protection in the belly holds involves suppressing, not extinguishing a fire until the airplane lands. Note that a cargo of lithium batteries could burn right through the cargo hold, unaffected by Halon (see ASW, July 26). Note that inaccessible spaces containing flammable materials and electrical components are not protected by detection or suppression. Note further that current regulations involve less stringent flammability standards for materials used within the pressure vessel but which are outside the occupied areas. In other words, the materials in hidden spaces may be more burnable (see ASW, March 22). Note further concerns expressed earlier this year by Wendy Tadros of the Transportation Safety Board of Canada about the lack of progress regarding the need for integrated strategies to combat in-flight fires * The crew used up most of the portable fire-fighting gear to extinguish the blazesDiverse product range on show at Railtex: companies from 17 countries will be exhibiting at this year's Railtex exhibition being staged at Britain's N

Maintenance prevents refrigeration failure, product loss
It's an hour out from the dinner rush, and the walk-in refrigeration unit in the kitchen decides to go on vacation. What do you do?
Before cashing in your chips, consult the backup plan that you put in place for just such an occasion. Because, of course, you have a backup plan in place in the event of equipment failure or power outage, right?
Most hotels have backup power generators that will handle the power outage, but if the equipment breaks, how do you protect all of the contents?
Bob Ducy, director of engineering at the Fairmont Scottsdale (Ariz.) Princess, is responsible for about 40 Scotsman and Hoshizaki ice machines, 10 walk-in coolers and freezers and 40 to 50 reach-in units at the 651-room property.
His backup plan requires that the other units have enough space to accommodate product transferred from any unit that fails.Product can be moved quickly subsequent to sending in the repairman to trouble shoot," Ducy said. "Parts are ordered and replaced if needed and the cooling system is put back online."
Becoming familiar with the equipment and commonly occurring problems are paramount to avoiding a complete breakdown, according to Tom Sheridan, owner of the 22-room Taughannock Farms Inn in Trumansburg, N.Y.
"Have a relationship with the contractor, be around as much as possible, get involved and discuss a problem and why it happened, so when symptoms occur--before a shutdown--you can say, 'Here's what's going on.'" Sheridan said. "You can speak to them intelligently."
There is one walk-in, outdoor cooler at the property, which needs to be at peak performance.
"You don't have to be an expert," Sheridan said. "It's about being generally aware of the components ... knowing that in some cases if you clean off the condenser or evaporator your problem is solved."
In most cases, refrigeration units are online with a backup generator if a power outage occurs.
The 402-room Radisson Plaza Hotel Myrtle Beach (S.C.) Convention Center has a 500-gallon diesel fuel unit that can supply power to essential systems for two working days, said David Nobers, director of operations.
The hotel has one icemaker on each of 10 guest floors, two additional icemakers in the kitchen and bar areas and three walk-in units.
Two of the walk-in units are located in the main kitchen and a third is off the kitchen in a service hallway. The third unit sometimes is shut down during the off season to conserve energy.
"We have the ability to consolidate cheese, milk and vegetables into the larger of the two main units if necessary," Nobers said.
As an extra precaution, the Fairmont Scottsdale Princess has an agreement with a refrigerated truck company to be on the property within an hour of a power failure.
"Between our generator and the redundant space, we have not used it," Ducy said.
At the Glenview (Ill.) Courtyard by Marriott, the expertise of the engineering department is the only safeguard against spoiled food and broken ice machines. The refrigeration equipment is not attached to a backup generator.
GM fleet and commercial operations: big trucks mean big sales for General Motors Who knew that GM's five-year-old Fleet and Commercial Operations (FCO
Who knew that GM's five-year-old Fleet and Commercial Operations (FCO) accounts for 1.3 to 1.5 million vehicles a year-some 28 percent of GM's U. S. sales? On the commercial side alone, consider that more than 14 million U.S. businesses, from morn and pop grocers to giant retailers, own vehicles. While GM divisions traditionally have had their own fleet and commercial departments, they were consolidated in 1999. FCO now represents all GM car and truck divisions and products ranging from small cars to massive "medium-duty" trucks, with business sub-divided into three categories: rental, commercial and government.
Medium Duty
Chevrolet Kodiak medium-duty workhorses, in regular and crew cab configurations with wheelbases ranging from 152 to 235 in., get available factory-engineered 4WD for 2005. Enhancing their off-road capability is an electronically controlled New Venture Gear Model NV273 2-speed transfer case with a dash-mounted rotary selector switch for 4L 4H and 2H drive settings. Power choices are standard Vortec 8100MD gas V-8 or optional Duramax 6600 Turbo Diesel V-8, both driving through an Allison 1000 Series 5-speed automatic transmission. GM's Stabilitrak stability control system became standard on GMC Savana and Chevy Express long-whedbase 12-and 15-passenger vans late in the '04 modal year and expands to regular-wheelbase 12-passenger models for '05. Four engines are available: 200-hp Vortec 4300 V-6, 275-hp Vortec 4800 V-8, 285-hp Vortec 5300 V-8 and 300-hp Vortec 6000 V-8. All are mated to either a Hydra-Matic 4L60-E or a 4L80-E transmission with a unique tow/haul feature that improves the predictability and reduces the frequency of shifting during towing.
Military
FCO provides a wide range of vehicles to the U.S. Military and its allies. Cargo and troop carriers derived from regular and crew cab CheW Silverado heavy-duty pickups are powered by a 6.6L Duramax turbo diesel V-8 (upgraded for '05 to 310 hp and 605 lb.ft, of torque) coupled to an Allison 1000 Series 5-speed automatic transmission with a New Venture 2-speed transfer case. For especially "arduous" terrain, an available Enhanced Mobility Package includes two-piece wheels with a beadlock feature that positively secures the tire to the rim even when air pressure is lost. Medium-duty military offerings include troop and cargo careers and specialized models equipped as field workshops, shelter carriers, wreckers, ambulances, tankers, dump trucks and more.
Alternative Fuel Vehicles
Last year, GM introduced gas/electric hybrid CheW Silverado and GMC Sierra pickups for fleet sales. Powered by a Vortec 5300 V8 coupled through a cleverly packaged electric motor/generator to a 4-speed automatic transmission, they offer flail pickup capabilities with 10 percent better fuel economy and four 120V electrical power outlets. GM also offers a range of vehicles equipped to run on E85 (85 percent ethanol, 15 percent gasoline) and is the only OEM offering compressed natural gas (CNG) models, both bi-fuel and dedicated, for '05.

Surviving Florida's ill winds: what LTC providers learned from battling four hurricanes
It wasn't a record you'd want to set: the first state since Texas in 1886 to be ravaged by at least three major hurricanes in one season. Florida, as everyone knows, was hit by Hurricanes Charley, Frances, Ivan, and Jeanne within the space of five weeks in August and September. (As of this writing, the hurricane season had several weeks to go until the traditional November 30 conclusion.) The personal devastation experienced by Floridians was immense, and many small businesses were put out of business for good. In the middle of it all were long-term care facilities housing some of the state's most vulnerable people. The facilities themselves, confronting not only storm damage but the prospects of a costly cleanup, were in frail condition, as well. How did they get through it? What did they learn? What happens next? Here are observations gleaned from providers and provider organizations by Edward Susman, a local writer on special assignment, and interviews with LTC association officials by Nursing Homes/Long Term Care Management Editor-in-Chief Richard L. Peck.
By Edward Susman: "For us, evacuation was never really an option," said Daryl Miller, director of communications for the Joseph L. Morse Geriatric Center, Inc., in West Palm Beach. West Palm Beach, a community of 100,000 people, took staggering hits from the Labor Day Hurricane Frances and the Yom Kippur Hurricane Jeanne, three weeks later in September. "Our facility is rated to withstand a Category Five hurricane," Miller said, "so we are prepared to ride these storms out." She spoke as Jeanne gathered strength in the Atlantic and poised itself to slam into the Palm Beach County-Martin County areas on Florida's east coast.

Service key to success of waste-to-energy project: Perkins supplies additional engines for landfill power generation application
Together with its Belgian partner for electrical power generation projects, E. Van Wingen NV, Perkins Engines has recently supplied an extension to the electrical power generation capacity, at Belgium's largest landfill site.
The installation of six new power generation modules employing 90[degrees] V configuration versions of Perkins' 4000 series engines at the Mont-Saint-Guibert waste site brings the total to 13. Six of the existing seven modules date from a contract supplied in 1996 by Perkins and E. Van Wingen, (EVW), based in Evergem, a suburb of Ghent.
The power generation modules employ the 16-cylinder 4016 TESI spark-ignited gas engines (3.82 L/cyl., bore 160 x stroke 190 mm) built and adapted to landfill gas at Perkins works in Stafford, U.K. Driving Leroy Somer generators, each generator set produces 700 kW at 1500 rpm. Output voltage at the generator terminals is 400 V, which is stepped up to 11 kV for distribution to the Belgian national grid. With a combined output of over 9.5 MW Mont-Saint-Guibert delivers more than 200 million kWh to around 20,000 homes in the area, EVW estimates.
Mont-Saint-Guibert is operated by CETEM, a division of U.K. waste disposal specialists Shanks plc, and receives 300,000 tons of waste annually. The landfill gas produced is filtered and then compressed prior to cleaning, drying and screening so that the proportion of methane in the gas is around 50%. Since February 2003, CETEM reports the site has stopped accepting industrial waste, and the distinction is being made between poor and rich gases. Rich gases will contain more methane and will serve to fuel biogas engines. For the poor gases, Shanks is considering burning them to dry the sludge from wastewater treatment plants and then using the briquettes to fuel another installation that could be capable of generating another 4 MW. Initially, six 4016 TESI modules were installed in 1996, followed by a seventh module in 2002, bringing the total electrical output of the site to 5 MW. In the same year the original six engines underwent a 35,000 hour major overhaul, on the basis of which EVW and CETEM determined that the engines' life cycle could realistically be extended to 80,000 hours. At the time of writing, the oldest engines had logged over 45,000 operating hours, and are proving to be real workhorses, Perkins and EVW note. The recent engine commissioning is the result of a follow-up order placed by CETEM in 2003.
The Mont-Saint-Guibert site is expected to carry on producing sufficient gas to operate engines for the next 20 years, long after it ceases to accept household waste. Perkins notes that the landfill gas version of the 61 L displacement 4016 TESI engine is well suited to installations where there is good gas maturity. For installations where the amount of gas precludes the use of larger power modules, the company is developing and introducing a higher efficiency, low-emissions module, like the smaller, six-cylinder 4006 TESI landfill gas engine. Rated 402 hp at 1500 rpm, it can be used at sites before and after the normal 15 to 20 years of gas maturity, maximizing site life and enhancing potential revenues from electricity generation.
Perkins explains that E. Van Wingen has been a major instrument in helping it develop a presence in the European power generation marketplace. As a niche operator, putting the emphasis on service and quality, the company has built up a portfolio of installations across a variety of applications, including the extremes of landfill sites and horticultural installations. In total, the Belgian company has purchased and packaged over 1500 engines for these applications. It has assisted in the field-testing of a number of new Perkins engine ranges, including the 2800 series, 2300 series and the 4000 series diesel and gas families. The validation work in the field has meant not only shortened development times but also improved quality of the final product, Perkins stated.
Under Perkins' OEM partners philosophy, it works with specific OEMs that specialize in providing total support to the customer and end-user. Perkins and EVW signed the first OEM partnership agreement in 2002, representing a charter to formalize commitment to the end-user, the companies stated. The agreement underlines the pursuit of excellence in customer support, described in a mission statement endorsed by both partners. Under the agreement EVW takes the full Perkins product range (400 to 4000 series), and the staff are trained across both diesel and gas products. Customers benefit from having competent engineers at hand, Full overhaul and maintenance programs and guaranteed genuine Perkins parts.
Jean-Pierre Van Wingen, general manager of EVW notes that organization and service are keywords. "Our solid know-how is backed by our dynamic team of well over 40 staff and the off-the-shelf availability of- spare parts."

Heat and power for school district
Cummins Northeast Inc., the Dedham, Mass., distributor for Cummins Inc., recently completed a cogeneration project in upstate New York that is said to be the first grid-independent, cogeneration performance project of its kind in a New York school system. The installation provides the Fonda-Fultonville school district with all the energy necessary to heat and cool its single-campus institution, thus achieving significant energy efficiency and cost savings, Cummins Northeast said.
"This installation represents a major milestone for the Fonda-Fultonville school district, Cummins Northeast and the state of New York," said Brian Balcom, general manager for Cummins Northeast Energy Systems. "In this age of rising costs associated with energy production, cogeneration is a valued solution to combat high prices while providing reliable, clean energy."
The Fonda-Fultonville school project began in 1999 as a capital project in response to rising utility costs and the school district's desire to build new buildings, renovate old facilities, and upgrade the parking lots and athletic fields. As a single-campus institution, Fonda-Fultonville was financially burdened by the electricity necessary to heat and cool all its buildings When the capital project exceeded the budget, the school district turned to Atlantic Energy Services Inc. (ESCO), an energy services company, to design a grid-independent, cogeneration project that would guarantee energy savings. Atlantic Energy Services in turn chose Cummins Northeast to provide a reliable, efficient and cost-effective energy solution.
Cummins Northeast is the distributor for Cummins and Onan in New England and Upstate New York. Headquartered in Dedham, it has locations in Buffalo, Syracuse, Albany and Rochester, N.Y., Springfield, Mass., and Bangor and Scarborough, Maine.
"As a result of the Cummins Northeast off-grid project, we estimate that the Fonda-Fultonville school district will save $275,000 each calendar year," said Glenn Goodale, superintendent of schools. "Instead of spending money on energy, we could now focus on reducing our budget, introducing new social and instructional programs, enhancing our district staffing, and directly impacting the teaching and learning programs."
The power facility itself generates energy at a lower rate through its four, 334 kW Cummins natural gas-fired generator sets and a 1 MW Cummins standby diesel generator set. All of the generator sets are packaged within sound attenuating enclosures. The operation of the gen-sets is through Cummins PowerCommand controls, and the switchgear was also provided by Cummins Power Generation.
While natural gas is consumed to produce electricity, the heat produced from the generator exhaust is routed through Beaird Maxim heat recovery steam generators to produce heat for the building, thus replacing the heat that would have been required from the facility's boiler system. The plant also features a 250-ton Cention absorption chiller that lowers electricity consumption by converting waste heat into chilled water that can be used for air conditioning.
"This off-grid school facility is the largest of its kind between Rochester and Albany," said Chris Cafer, associate at Energy Concepts Engineering PC, the project's engineering firm "It's a substantial undertaking to go off-the-grid for energy, but this is truly the most effective, efficient cost-savings solution to powering, heating and cooling the Fonda-Fultonville school's facilities. By driving the school district's costs down, the installation of the cogeneration plant allows school officials to more effectively manage internal operations and maintenance issues."

Pesa puts on impressive display
POLISH rolling stock manufacturer, Pesa, was a prominent exhibitor at InnoTrans, displaying some of its latest vehicles and wagons at the outdoor section of the show. Displays included a new 120km/h diesel rail bus (above) designed for Ukrainian Railways (UZ), a sleeping car for Polish State Railways' (PKP) Intercity services, and a new eight-axle self-discharging wagon for PKP's freight division, PKP Cargo.
The 26.4m-long air-conditioned rail bus for UZ features ergonomically-furnished drivers' cabs, space and toilets for disabled passengers, and two sliding doors on each side of the vehicle to allow easy access. The 315kW engine is built by MTU, with gear, compressor, and generator equipment provided by Voith, and the pneumatic brake system is supplied by Sab Wabco.
The air-conditioned sleeping car includes two class A compartments and a mix of first and second class compartments, providing a total of 28 berths, plus 29 seats and a toilet suitable for disabled passengers. The class A compartments include a toilet, refrigerator, and an audio-visual DVD system. The car can be operated at up to 200km/h Pesa's latest specialised freight wagon, the new Feelrrs series eight-axle self-discharging wagon, consists of four close-coupled dump units with a total capacity of 192[m.sup.2]. Side hatches are opened using either a control panel at the front of the wagon or via a remote control unit.
Pesa manufactures a wide range of rolling stock, which also includes emus and light rail vehicles. Its market has been largely domestic until recently, with some orders from eastern Europe, but it now plans to expand its sales throughout Europe and believes it can launch a serious challenge in future to established manufacturers such as Alstom, Bombardier Transportation, and Siemens.

New flexible control system from engineering concepts unlimited
Engineering Concepts Unlimited (ECU) recently launched a new engine control unit for engine generator set and pump set control. While targeted primarily toward the smaller end of market, the new 9960 Series control has enough flexibility and capability to be suitable for application in ECU'S more traditional larger engine installations, according to Adam Suchko, president of the Fishers, Ind., manufacturer.
"These units can be configured for everything from ultra-simple to reasonably complicated applications," said Suchko. "It is really targeted at small sets and pumps, but it has just enough capability to eke onto a regular set. It's probably one of the most flexible controls we've ever offered."
The new 9960 Series control is a fully potted unit housed in an ECU standard (2.9 in. x 3.1 in. x 1 in.) zinc case. It can accommodate as many as three 40 amp relays and a total of 12 connections to monitor and control a range of engine conditions and functions. Faston connectors are used to provide high power and density and facilitate quick installation, Suchko noted.Battery monitoring with auto start at low voltage, low voltage timer and automatic stop at high voltage.
* Glow plug, starter and fuel.
* Frequency and ac voltage of the speed input.
* A range of optional capabilities such as pressure and temperature sensing, run-time monitoring, etc.
"It can be custom ordered in many different versions that allow even the small packager to have his own OEM-style control," noted Suchko. "There is a lot of capability packed into this."
The control can be set up to run on generator output voltage or magnetic pickup and incorporates a proprietary processing algorithm for ac to avoid problems with load noise. On-board high current relays are designed to eliminate the need for pilot relays on most small gen-sets.
"Loads are orchestrated to allow one inline fuse to pretty, much handle it, since we make sure the starter and glow plugs aren't on at the same time," Suchko said.
Depending on the version, information can be displayed on LEDs and can also be sent to an external readout, such as a laptop or an optional screen display. The system can be used with any other ECU engine control product and Suchko said the system configuration can be altered by the use of an external programming device. The customer may choose whether he wants to have field programmable or factory programmable adjustment capability.
"One version allows for multiple station operation of the gen-set anywhere in the vehicle or building," Suchko said. "A simple external on/off push button controls it and a single wire for an external light or LED allows monitoring from anywhere using simple flash codes. A push rocker switch with built-in LED makes them great for truck dashes."
Suchko added that ECU was planning to incorporate software into the 9960 Series control, essentially "turning the unit into a small PLC for doing speed and timing.
"We can't thank our customers enough for their continued support and we continue to listen to their needs for simple, robust engine controls that deliver years of solid reliability," Suchko added, also noting ECU's ability to respond quickly. He cited one case where the company "delivered a replacement part to Juneau, Alaska, for the FAA on a VOR system on an island. Our staff arranged for airline transit to have it there as quickly as possible per the customer's request."
The 9960 Series control is the latest in a growing range of products from ECU that includes CAN-bus engine controls, speed switches, voltage detectors and other components and modules, primarily for stationary engine systems.

Permitting the holy grail of data centers: reliability meets emissions, leading UPS data center to SCR emissions control
To say that United Parcel Service relies heavily on data is as obvious as saying people need blood. Data is the lifeblood of UPS' global package delivery network. Exactly where a package is, and when it will be delivered, all monitored in "real time" is vital to UPS' operations.
At any given time there are about 45 million packages in the system, more during the holidays. About 14 million parcels daily are put in motion with their every move recorded, tracked and analyzed.
As a result, UPS takes data very, very seriously. This is immediately obvious at UPS' Windward data center in Alpharetta, Ga., a facility one computer manufacturer called the "holy grail of data centers." Windward, opened in 1995, is one of two UPS data centers, along a facility with in Mahwah, NJ., built in 1989 and expanded to a Tier IV data center in 1995.
How serious the Windward operation protects its data is seen in the fact that it was the first Tier IV data center as classified by the Uptime Institute (see accompanying article). According to the Uptime Institute, Windward was the first site to assume the availability of dual-powered computer equipmen As a result, the facility has achieved "five nines" of reliability over its nine year history, with a goal of "six nines" a mark the operations has achieved "from time to time." Five nines is 99.999% reliability, essentially meaning only one out of several hundred computer servers can be offline less than 30 seconds annually.
In developing the dual-powered computer hardware necessary to achieve Tier IV reliability, UPS worked with most of the major computer manufacturers.
According to Joe Parrino, Windward facilities engineering manager, one computer manufacturer, who was surveying data centers throughout North America, visited the Windward operations and said, "what you're building here is the holy grail of data centers."
"He later told us that we are performing reliability-related tasks that other people didn't even have awareness of," Parrino said.
In 1995, to back up Windward's extensive computer operations, UPS installed six, 1.6 MW Caterpillar 3516B diesel generator sets with Kato generators engineered and packaged by Yancey Power Systems, Austell, Ga. The sets are located in a pair of engine rooms, the A side and B side. The gen-sets were designed to be used both for backup and peak shaving operations.
Again, underscoring how serious UPS and Windward are about reliability is the fact that there is 9.6 MW of installed power at a facility with a 2 MW load. And, the plant is built to house an additional six similarly sized sets for a possible total of nearly 20 MW on-site.
Parrino said Windward uses the generator sets during a total loss of utility power, during brownouts/voltage swells or grid instabilities, during power switching activities from other users on the nearby grid, during maintenance or troubleshooting by Georgia Power, as well as peak shaving when the cost of electricity exceeds 7 cents/kWh.
