Cummins Inc. announced an expansion of its U.S. Environmental Protection Agency (EPA) Tier 3 certified marine generator products during the Miami International Boat Show.

The company will feature a new Onan Marine QD series generator with a power range of 40 kWe to 65 kWe. The latest Tier 3 QD generators offer customers reduced emissions with the quiet operation.

The expanded power range of the Onan marine QD Series generators comes just as recreational vessels are Source: Cumminsrequiring more electrical capacity to power increasing house loads. Boaters see their vessels as an extension of their home with comfort expectations that have driven additional electrical loads. Additional lighting, ice makers, satellite TV, air conditioning, gyro stabilization, full service kitchens and washer/dryers have become the norm demanding more electricity in vessels of all sizes.

The new platform can be paralleled, allowing it to provide electrical power for vessels with a need up to 130 kWe enabling Cummins to offer a QD Series product for a larger class of yacht. Providing a single platform with a wider power output range provides boat builders more flexibility to offer their customers the amenities they desire, knowing Cummins can provide a generator for all of their electrical needs without having to redesign their engine room layouts.

The new product will be available in a variety of configurations including two cooling system options, heat exchange or keel cooled, with or without the Onan sound shield and also with single or three phase power options. The new power range will be sold under six different model names, MDDCS, MDDCT, MDDCU, MDDCW and MDDCY, depending on the kilowatt and the hertz requirement.

Cummins also recently announced the unification of its brand strategy across its Power Systems business segment, which provides high-speed engines from 760 – 4400hp and power generation equipment from 2-3,500kW, including standby and prime power gen sets, alternators, switchgear and other components. Previously the portfolio featured the Cummins, Cummins Power Generation and Cummins Onan brands. Moving forward the branding will be consolidated under the Cummins brand. The Cummins Power Generation and Cummins Onan brands have been retired and the Onan name synonymous with mobile gensets, has been repositioned as a generator product line.
