Phasor K4-12.5 – 12.5kW Marine Diesel Generator 1800 RPM

Phasor K4-12.5 – 12.5kW Marine Diesel Generator 1800 RPM

Solving the need for high-endurance power in a mid-sized frame, the Phasor K4-12.5 operates at a steady 1800 RPM for maximum longevity. This 12.5kW diesel generator is a staple for American cruising trawlers and sailing yachts that require a heavy-duty energy source for multi-zone air conditioning and hydraulic systems. For the USA captain, the K4-12.5 offers the legendary reliability of a 4-cylinder Kubota engine, delivering a stable 60Hz current that ensures your vessel remains fully operational during long offshore transits from the Eastern Seaboard to the Caribbean.

Built on a rugged cast-iron base, the Phasor K4-12.5 emphasizes mechanical simplicity and ease of service with a single-side maintenance layout. The low-speed 1800 RPM design inherently reduces mechanical stress and acoustic vibration compared to high-speed alternatives. With its brushless alternator and high surge capacity, this model provides the American market with a “lifetime” power plant that excels in continuous-duty applications where reliability and quiet operation are the primary objectives.
