Separate circuit aftercooling system
The primary advantage of the separate circuit aftercooling system (SCAC) is that no sea water circulates through the aftercooler
C18 High Performance Propulsion Engines
The C18 marine propulsion engine has high performance commercial application ratings of 814-1015 mhp (803-1001 bhp) at 2100-2300 rpm that meet U.S. EPA Tier 3, IMO II, and EU Stage IIIA emissions regulations. In addition to meeting the stricter EPA Tier 3 emissions, this engine now offers a fresh water aftercooled option for the commercial propulsion and auxiliary engines and genset packages. From fishing to offshore and everything in between, you can be confident that we have the solution to fit your needs.
