Specification sheet Diesel generator set

1 Specification sheet Diesel generator set 25 kW - 40 kW. EPA emissions stationary standby Description Cummins Power Generation generator sets are Cooling system - Standard cooling package fully integrated power generation systems provide reliable running at up to 50 C (122 F). providing optimum performance, reliability and ambient temperature. versatility for stationary standby applications. Enclosures - The aesthetically appealing Features enclosure incorporates special designs that Cummins heavy-duty engine - Rugged 4- deliver one of the quietest generators of its kind. cycle, liquid-cooled, industrial Diesel engine Aluminum material plus durable powder coat delivers reliable power, low emissions and fast paint provides the best anti-corrosion response to load changes.

2 Performance. The generator set enclosure has been evaluated to withstand 180 MPH wind loads Alternator - Several alternator sizes offer in accordance with ASCE7-10. The intelligent selectable motor starting capability with low design has removable panels and service doors reactance 2/3 pitch windings, low waveform to provide easy access for service and distortion with non-linear loads and fault clearing maintenance. short-circuit capability. Fuel tanks - Two dual wall sub-base fuel tank Control system - The PowerCommand series are offered as optional features, providing electronic control is standard equipment and economical and flexible solutions to meet provides total generator set system integration extensive code requirements on Diesel fuel tanks.

3 Including automatic remote starting/stopping, precise frequency and voltage regulation, alarm NFPA - The generator set accepts full rated load and status message display, output metering, in a single step in accordance with NFPA 110 for auto-shutdown at fault detection and NFPA 110 Level 1 systems. Level 1 compliance. Warranty and service - Backed by a comprehensive warranty and worldwide distributor and dealer network.
