50kW Marine Prime Power Diesel Generator

This 50kW / 62.5kVA marine diesel generator set is a complete boat engine assembly specially built for vessel onboard power supply. Running at fixed 1500RPM speed for 50Hz operation, it adopts marine-grade diesel engine and water-cooled heat-exchanger cooling system matched with seawater pump for closed fresh-water circulation cooled by seawater.

Optimized for salt-fog corrosion, high humidity and heavy-vibration marine environment caused by vessel rolling and pitching. It serves as main auxiliary power or emergency backup power for fishing boats, small-medium cargo ships, working boats, ferries and yachts, supplying stable power for navigation instruments, communication devices and various ship-borne electrical loads.

Marine classification certificates including CCS, BV, ABS are optional for ship inspection and vessel registration.
