Gillette Manufacturing, Elkhart, Ind., has introduced a new diesel generator set with a rated power of 5 kW and a maximum output of 6 kW. The new gen-set is part of the company's Gen-Pro line of portable gen-sets which cover a range of 3 to 17.5 kW and are designed for heavy-duty applications such as contractor and job-site work.
The new GPNDL-60E gen-set is a single-phase, 60 Hz unit, but three-phase windings and 50 Hz output is also available. It is powered by an air-cooled Lombardini 6LD435 diesel engine rated 9.8 hp at 3600 rpm. The direct injection engine incorporates electric start, built-in battery charger and low oil protection. Other features include spin-on oil and fuel filters and an automatic bleed system designed to ensure easy starting in the event air enters the fuel system, which can occur when the engine runs out of fuel.
The engine drives a Gillette manufactured brushless generator that features the company's Power Assist and Kleen-Power designs. The Power Assist winding design incorporates 35 percent more copper wire and electrical grade steel due to its oversized generator diameter than the closest larger competitive designs, according to Gillette. This allows the generator to deliver a 50 percent surge in kW rating, which results in enhanced motor starting capabilities.
The Kleen-Power design allows only 7 percent harmonic distortion of the power sine-wave, which reduces the chances of damage to voltage sensitive loads, Gillette said.
Other features of the Gen Pro units include automatic load balance, which eliminates load chatter and excessive vibration due to unbalanced electric loads; and heavy-duty diodes and capacitor for longer service life.
The unit incorporates a heavy-duty, side-mounted control panel that includes a magnetic circuit breaker, individual circuit breakers for each 120 V receptacle, electric shock protection on each 120 V receptacle with added ground fault circuit interrupters, 120/240 voltmeter, Hobbs hourmeter for maintenance scheduling, full power 120 V receptacle and full power 240 V receptacle.
The receptacle panel is protected from abuse and weather with a full lexan decal.
The GPNDL-60E generator is lightweight (190 lb.) and compact (22 in. wide x 23 in. high x 28 in. long). A 4 gal. fuel tank provides a run time of 7.5 hours, based on 0.52 gph fuel consumption at rated load.
