Cat C32 Marine Generator Set
V12 32.1 L marine generator set, 550-940 ekW at 1500/1800 rpm, with separate circuit aftercooling, heat exchanger or keel cooling, and EPA Tier 4, IMO II/III switchable and EU Stage V ratings.
Description
The Cat C32 Marine Generator Set is based on a V12, 4-stroke turbocharged-aftercooled diesel with MEUI fuel system. All configurations use a separate circuit aftercooling (SCAC) system, which reduces aftercooler corrosion because no sea water circulates through the aftercooler.

- Frequency / speed: 50/60 Hz, 1500/1800 rpm
- Displacement: 32.1 L (1,959 in³); bore 145 mm, stroke 162 mm
- Emissions: EPA Tier 4, IMO II/IMO III switchable, EU Stage V (also EPA Tier 3, IMO II, EU IWW, China II ratings)
- Generator: SR5 form wound, permanent magnet excitation, 4-pole, 6 leads, 2 roller bearings, CDVR regulator, Class H insulation (Class F rise), IP23
- Dimensions: length 4,271-4,452 mm, width 1,528 mm, height 1,667 mm; weight approx. 7,131 kg
Key features
- Heat exchanger or keel cooling; optional front-mounted sea water pump on HEX configurations
- Electronic diagnostics, fault logging and engine protection mode for extended ambient conditions
- PT100 RTDs on stator windings and bearings; anti-condensation heaters
- IP23 protection suitable for fixed water-based local application fire-fighting systems (FWBLAFFS); System IV insulation for harsh environments
- Combined helical spring/rubber isolators under formed C-channel rails
Optional equipment
