IMO II and EU IWW compliant for all ratings

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

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.
