C32
Cat C32 Auxiliary / Diesel Electric Propulsion Engine (IMO III)
DESCRIPTION
C32 auxiliary/generator set engines 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 also contribute to minimizing owning and operating costs. The IMO II, IMO III, EPA T4, EU Stage V and China-II compliant ratings are available with heat exchanger or keel cooled options. Emission options may vary for each rating. Please consult your local dealer for more information.Emissions
