Cat C32 ACERT Generator Set (EPA Tier 3)

C32 ACERT generator sets incorporate a separate circuit aftercooling system (SCAC) for all configurations. The primary advantage of the SCAC systsem is reduced aftercooler corrosion since no sea water circulates through the aftercooler. Many other improvements on these engines contribute to minimizing owning and operating costs. The EPA Tier 3, IMO II, EU Stage IIIA compliant ratings are available with heat exchanger or keel cooled options. Heat exchanger configurations have an optional front mounted sea water pump.
