Cat C18 ACERT Marine Generator Set (Tier 3)

Cat C18 ACERT Marine Generator Set (Tier 3)

C18 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, keel cooled, or radiator cooling options. All major MCS type approvals available from factory.
