Cummins Inc. (NYSE: CMI) announced today the launch of the C550D5 (50hz) and C500D6(60hz) series diesel generator sets for prime and standby power applications globally.

This series is engineered to deliver higher power density over 15 and 16-liter competitors with 42 kVA per liter of displacement thanks to the robust and reliable Cummins QSZ13 engine with 13L displacement. The QSZ13 engine, featuring XPI fuel injection with 3-stage fuel filtration, protects from poor fuel quality.  The new S-range of alternators provides new aesthetics and CoreCooling™ technology.

“With these new models, we are excited to be able to offer the best-in-class power density and help customers reduce their costs with the other added features of these gensets,” said Ignacio Gonzalez, Cummins Director, Global Industrial Power.

Customers can reduce their cost of operation thanks to extended service intervals (500 hours for prime and 250 hours/2 years for standby applications). They will also enjoy the service-free crankcase breather with 99% liquid efficiency. Additionally, fuel efficiency gains are realized due to optimizations to the turbo charger, camshaft and fuel injectors.

Weather-protective enclosures provide peace of mind against the elements (50° LAT capability for standby ratings and 55° LAT for prime).

The new gensets provide less noise pollution thanks to sound attenuated enclosures with 103 dB LWA sound pressure and 74 dB(A) at 7m sound pressure. In addition, these new gensets feature multiple lifting points for configuration with enclosure or chassis lift, as well as optional dual skinned tanks for meeting regional environmental regulations.
