Phasor SEP-9.5 Radiator Cooled Diesel Generator 9.5kW 60Hz

The Phasor SEP-9.5 is a radiator-cooled diesel generator for applications requiring 9.5 kW of 120/240V single-phase 60Hz AC power. It uses a Kubota D1305-E three-cylinder diesel engine running at 1,800 RPM and a direct-coupled brushless generator with solid-state voltage regulation. The open-skid unit relies on its integrated radiator and engine-driven blower fan for cooling rather than a raw-water heat exchanger or keel-cooling circuit.

The generator includes a deluxe remote instrument panel with oil-pressure, coolant-temperature, voltage, and hour-meter gauges, plus automatic shutdown for low oil pressure and high coolant temperature. Proper installation requires sufficient airflow for radiator cooling, a correctly engineered exhaust route, diesel fuel system, start battery, AC distribution, grounding, and shore-power transfer equipment.

Electrical Compatibility

This generator is designed for 120/240V single-phase 60Hz AC distribution. Confirm running load, simultaneous demand, power factor, and the largest motor-starting surge before selecting a 9.5 kW genset. Consider high-demand equipment including HVAC, refrigeration compressors, pumps, watermakers, battery chargers, and galley appliances.

The radiator-cooled design requires dedicated ventilation that can remove heat from the radiator and provide sufficient combustion air. Evaluate engine-room airflow and hot-air discharge routing before selecting this configuration.

Installation Considerations

Install the generator on a rigid vibration-isolated foundation with service clearance for the radiator, fan, belts, oil, filters, coolant, electrical terminals, exhaust, and fuel connections. Provide diesel feed and return, safe exhaust routing, adequate ventilation, starting battery, AC circuit breakers, grounding, and a correctly designed shore-power transfer switch or interlock. Installation and commissioning should be completed by a qualified marine generator technician.

Before Ordering
