Kohler has added to its range of Tier III compliant marine diesel generators.

The new models range from 125 to 150 kW for 60 Hz, and 100 to 125 kW for 50 Hz and are specifically designed for commercial and superyacht marine applications. Both models feature a high-pressure common rail fuel system offering optimum performance and fuel efficiency.  They include a newly designed Kohler Decision-Maker 3500 (DEC 3500) controller equipped with paralleling software, saving much of the space and cost of switchgear.

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 synchronization.  It can be operated in one of three paralleling modes: P-gen (Kohler-patented), droop, or V-bias/S-bias.

The new generators feature:

Kohler’s newly designed Fast Response X (FRX) alternators with superior permanent magnet excitation
Isolated ground DC electrical system (standard)
Smaller footprint compared to previous Tier II Kohler models
In addition to existing heat exchanger and keel-cooling options, Kohler released inline radiator models as part of the company’s commitment to offer fully integrated solution for the workboat market.
