Phasor K3-8.5kW Marine Diesel Generator – 1800 RPM, Standard Series

Low-speed 1800 RPM mechanical rotation stabilizes the Phasor K3-8.5kW Marine Diesel Generator, delivering exceptional electrical longevity for commercial workboats and offshore cruising yachts. This heavy-duty generator supplies 8.5 kW continuous output and 10.0 kVA surge power at 120V and 240V 60Hz, running multi-stage air conditioning chillers, electric galley ranges, and hydraulic steering pumps.

Built around a heavy-duty three-cylinder Kubota diesel engine, the platform includes a freshwater-cooled exhaust manifold and cast-iron cylinder liners. The synchronous four-pole alternator features 100 percent copper windings dipped in Class H thermal varnish to resist moisture. Weighing 435 lbs dry, the generator mounts inside a footprint measuring 33.5 inches long by 20.5 inches wide by 24.0 inches high.

Key Features of Phasor K3-8.5kW

Commercial captains who buy Phasor K3-8.5kW marine diesel generator hardware gain proven commercial power equipment built for continuous oceanic service. Operating at 1800 RPM minimizes mechanical stress on engine rod bearings and piston skirts, delivering thousands of trouble-free running hours between major engine overhauls.

- 8.5 kW continuous electrical capacity powers multiple commercial kitchen appliances and central air chillers at once.
- 10.0 kVA surge rating starts large inductive watermaker pumps and hydraulic bow thrusters without breaker trips.
- Synchronous alternator design delivers steady 60 Hz electrical power across sudden electrical step-load additions.
- Complete freshwater cooling covers engine block and exhaust manifold, transferring heat out through raw-water exhausts.
- K3-8.5kW standard series frame features heavy rubber isolation mounts to prevent hull resonance.
- Four-pole brushless alternator eliminates slip rings and carbon brushes to minimize maintenance downtime.
- Cast-iron cylinder sleeves ensure long operational life and compression retention across extended voyages.
- Automated engine shutdown protections guard against cooling failure, high exhaust temperature, or low oil pressure.

Inductive Load Surge Acoustic Measurements

Producing 56 dB(A) at 23 feet when enclosed in a sound shield, this diesel unit operates without intruding into vessel living quarters. The solid-state automatic voltage regulator holds output voltage within 2 percent of 120V and 240V standards at 60 Hz. Sudden step-load applications from galley induction ranges are absorbed without frequency droop, consuming 0.58 GPH at 50 percent load.

Engine Bed Fitment Exhaust Plumbing

Install the generator on rigid structural stringers above bilge flood lines, leaving 12 inches of service clearance around capsule panels. Connect raw water supply through a dedicated 0.75-inch bronze seacock with an inline sea strainer. Grounding circuits link to vessel bonding buses through isolated ground returns to prevent galvanic zinc loss.

Marine Usability Scheduled Inspection Steps

Service technicians check fluids and filters through an unencumbered single-side maintenance layout. This generator is not engineered for land-based operations without cooling water, nor for direct electrical integration with uninsulated shore lines lacking marine galvanic isolation switches.

- Inspect sea strainer baskets and raw-water pump drive belts before each shift.
- Renew engine oil and replace primary fuel filters every 100 runtime hours.
- Inspect zinc anodes and check alternator insulation resistance every 250 runtime hours.
