Phasor YK4-45.0 45kW Keel Cooled Diesel Generator

Demanding ocean-going trawlers and commercial tugs draw heavy prime power from the Phasor YK4-45.0 digital generator, which drives a 3318cc 4-cylinder Yanmar diesel at 1800 RPM, producing 45.0 kW across a keel-cooled 1450-lb frame.

  • 45.0 kW prime rating powers complete vessel grids
  • Yanmar four-cylinder engine delivers rugged continuous torque
  • Keel cooling loop prevents raw-water strainer clogging
  • Optional 120/208V three-phase configuration runs heavy motors
  • Full-monitoring gauge panel ensures automated safety protection

The Phasor YK4-45.0 is a heavy-duty keel-cooled marine diesel generator for commercial and large-vessel installations requiring 45 kW of 120/240V single-phase 60Hz AC power. It uses a Yanmar 4TN100 four-cylinder diesel engine operating at 1,800 RPM with a direct-coupled brushless generator and solid-state voltage regulation. The open-frame generator is designed for vessels with a correctly engineered keel-cooling, grid-cooling, or skin-cooling circuit.

The generator uses an engine-driven circulation pump for its closed coolant circuit and requires external hull cooling sized for the engine and generator heat load. It includes a deluxe remote gauge panel with engine monitoring and automatic shutdown for low oil pressure, high coolant temperature, and overspeed. An optional sound enclosure may be available separately, subject to the selected configuration.
