Key Specifications

 

Minimum rated power

550 eKW (688 kVA)

Maximum rated power

940 ekW (1.175 kVA)

Frequency

50 Hz or 60 Hz

One of the main peculiarities of the C32 ACERT generator sets lies in the fact that they incorporate a separate circuit after-cooling (SCAC) system for all configurations. This system allows for less corrosion of the aftercooler through which no sea water circulates. Thanks to the C32 ACERT generator sets and their features you will be able to reduce ownership and operating costs to a minimum. Engines rated to IMO II and EU Stage IIIA standards are available with heat exchanger or keel cooling. Heat exchanger configurations allow optional front mounting of the seawater pump.
