Kohler's latest Tier III compliant generator

Kohler Power Systems, a manufacturer of diesel and gasoline marine generators, has introduced updated emissions-compliant diesel generators, ranging from 40 to 99 kW for 60 Hz, and 33 to 80 kW for 50 Hz. The new models are smaller and quieter and include a newly designed Kohler Decision-Maker 3500 (DEC 3500) controller equipped with paralleling software and load-management software – allowing for automatic paralleling of two generators without the cost and extra footprint of switchgear.

“While load requirements have increased due to advanced electronics equipment, on board space is still at a premium,” said Frank Formas, engineer at Kohler Power Systems. “Our new paralleling controller matches power capacity with load needs to eliminate under-loading and over-fuelling, while conserving space, decreasing fuel costs and reducing equipment maintenance.”

The Kohler DEC 3500 offers a newly designed customer interface for easier data entry and retrieval. Advanced features include bus sensing, first on logic and synchronisation. It can be operated in one of three paralleling modes: P-gen (Kohler-patented), droop, or V-bias/S-bias.
   
The new generators feature a high-pressure common rail fuel system on Tier III emissions-compliant models offering optimum performance and fuel efficiency; Kohler’s newly designed Fast Response X (FRX) alternators with superior permanent magnet excitation; isolated ground DC electrical system (standard); improved sound shields and mounts for decreased noise levels and less vibration; and a smaller package versus older Kohler models (103 to 407mm shorter without sound shield; 134 to 445mm shorter with sound shield).
