Yuchai YC12VC1850L-C22 1500kVA Open Frame Marine Diesel Generator Set 3 Phase 4 Wire Output

This 1200kW /1500kVA heavy-duty open-frame marine diesel generator set is driven by genuine Yuchai YC12VC1850L‑C22 V12 marine-grade diesel engine. Specially engineered for large-vessel onboard power supply under harsh salt-fog, high-humidity and heavy-vibration marine operating environments. Configured with marine heat-exchanger cooling system and dedicated seawater pump for closed fresh-water circulation cooled by seawater. Rated 60Hz, 3-phase 4-wire output, 24V DC electric starting system. Open-frame structural design provides excellent heat dissipation and easy access for inspection and maintenance inside large ship engine rooms. It serves as main auxiliary power or emergency backup power for ocean-going cargo ships, large fishing vessels, passenger ferries and offshore working crafts. Marine classification certificates including CCS, BV, ABS, EIAPP are optional for ship inspection, registration and marine-project tender.
