C32 ACERT IMO II

SPECS SUMMARY

Minimum Rating	550 eKW (688 kVA)
Maximum Rating	940 ekW (1175 kVA)
Frequency	50 Hz or 60 Hz
Speed	1500 rpm (50 hz) or 1800 rpm (60 hz)

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 IMO II and 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.
