Two new containerized and mobile Cummins Rental Power units contain two generator sets in a single sound-attenuated enclosure. C1600D6RG 1600 kW has two 800-kW generator sets, and C2000D6RG 2 MW has two 1000-kW generator sets. Two gen sets provides redundancy for critical loads, the company says, and also provides higher starting capacity and fuel economy. Cooling system is designed to handle temperatures up to 122 F, and Cummins says the generator can operate at maximum load in temperatures hgher than 90 F.
