Separate circuit aftercooling system

The primary advantage of the separate circuit aftercooling system (SCAC) is that no sea water circulates through the aftercooler

Emissions

EPA Tier 3 compliant, IMO II and EU IWW compliant

Cooling system

Heat exchanger and Keel cooled options for all ratings

Turbo Configurations

Single turbo configurations for all ratings

Competitive size and weight
