📝 Description

This Used Cummins DQCA diesel generator set, serial number C090235145, provides 600 kW standby and 545 kW prime power. Powered by a Cummins QSK23-G7 NR2 engine (SN: 00319501), rated at 1220 HP @ 1800 RPM, this generator is EPA Tier 2 emissions compliant and built for reliable performance in demanding environments.

This unit includes a PMG (Permanent Magnet Generator) and oversized generator end rated at 740 kW, enhancing voltage stability and load response. The 12-lead reconnectable alternator provides flexible voltage configuration, including 277/480V. The unit is equipped with a PowerCommand 2100 digital control panel, a 1200 Amp main-line circuit breaker, a Sens 10A battery charger (ships loose), and a coolant heater (208/240/480V).

Enclosed in a sound-attenuated Level 1 enclosure, it sits atop a 660-gallon UL142-listed sub-base fuel tank with secondary containment. The system has 685 hours, was built in 2009, and passed load testing on 4/3/2025, confirming its operational readiness.
