CAT® C4.4 MARINE GENERATOR SET
Cat® C4.4 Diesel Marine Generator Set has three phase ratings of 50 Hertz at 38.0, 51.5, and 69.0 ekW with heat exchanger cooling and at 36.0, 49.0, and 65.0 ekW with radiator cooling that meet EU CCNR2 emissions standards. The C4.4 also has three phase ratings of 60 Hertz at 44.0, 58.5, 76.0, and 99.0 ekW with heat exchanger cooling and of 42.0, 56.0, 72.0, and 95.0 ekW with radiator cooling. C4.4 gen set is available in 12 or 24 volt as an open gen set or as an enclosed package. Single-side servicing improves ease of maintenance and lowers overall owner operating costs. The compact package size is ideal for a wide range of commercial and pleasure craft applications. These ratings also have Marine Classification Society approved packages available.
