BENEFITS

Cooling System

Heat exchanger and Keel cooled options for all ratings

Emissions

IMO II and EU IWW compliant for all ratings

Separate Circuit Aftercooling System

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

Additional Ratings

Specific ratings are available that meet IMO II emissions regulations and additional ratings are available that meet both EPA Tier 3 and IMO II emissions regulations.
