Rugged 4-cycle, industrial diesel delivers reliable power, low emissions and fast response to load changes.

Several alternator sizes offer selectable motor starting capability with low reactance 2/3 pitch windings, low waveform distortion with non-linear loads and fault clearing short-circuit capability.

The PowerCommand® electronic control is standard equipment and provides total genset system integration including automatic remote starting/stopping, precise frequency and voltage regulation, alarm and status message display, AmpSentryTM protection, output metering, auto-shutdown at fault detection and NFPA 110 Level 1 compliance.

Standard integral set-mounted radiator system, designed and tested for rated ambient temperatures, simplifies facility design requirements for rejected heat.

Optional weather protective and sound attenuated enclosures are available.

Dual wall sub-base fuel tanks and in-skid day tanks are also offered.

The genset accepts full rated load in a single step in accordance with NFPA 110 for Level 1 systems.
