Phasor K3-8.0kW Marine Diesel Generator – 1800 RPM, Compact Series

Cramped commercial vessel machinery rooms crowd equipment, making the Phasor K3-8.0kW Marine Diesel Generator an ideal compact power plant for offshore fishing trawlers and passenger catamarans. Operating at a low-wear 1800 RPM, this generator produces 8.0 kW continuous output at 120V and 240V 60Hz, keeping galley cooktops, deep freezers, and deck wash pumps energized.

A water-cooled three-cylinder Kubota diesel engine drives a heavy-duty synchronous alternator built with 100 percent copper windings. Class H insulation materials shield internal stator coils against moisture-induced insulation breakdown. Supported by a powder-coated steel drip pan with elastomeric vibration isolators, this 410-lb dry weight generator features exterior dimensions measuring 32.0 inches long by 20.0 inches wide by 23.5 inches high.

Key Features of Phasor K3-8.0kW

Vessel operators who buy Phasor K3-8.0kW marine diesel generator systems obtain low-speed commercial power equipment engineered for continuous open-water duty cycles. Low 1800 RPM operation extends engine overhaul intervals while dampening structural hull vibrations across long commercial fishing expeditions.

- 8.0 kW rated electrical output delivers continuous power for watermakers, galley appliances, and air handlers.
- 9.5 kVA surge capacity handles momentary locked-rotor starting current from marine air conditioning pumps.
- Low-speed 1800 RPM operation reduces piston friction and extends mechanical overhaul intervals on commercial vessels.
- Kubota three-cylinder diesel block provides smooth mechanical balance and low rotational vibration.
- K3-8.0kW compact marine chassis slips into narrow engine spaces inaccessible to standard commercial gensets.
- Cupronickel heat exchanger tubes prevent saltwater erosion across long oceanic commercial passages.
- Electric 12V remote starter allows captains to start and stop the generator from the bridge console.
- Automated shutdown sensors protect the engine against overheating, low oil pressure, or cooling water loss.

Transient Load Voltage Drop Behavior

Emitting 56 dB(A) at 23 feet inside an optional sound shield, this diesel generator prevents noise fatigue across crew rest quarters. An integrated automatic voltage control maintains output voltage within 2 percent of 120V and 240V standards, preventing current drops during heavy compressor motor startup cycles. Operating at half load, the diesel engine burns 0.55 GPH, providing dependable and economical electrical power.

Machinery Space Plumbing Clearance Specs

Install the generator on level stringers at least 15 inches above bilge water 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.

Physical Accessibility Maintenance Protocol Steps

Single-side access permits rapid inspection of fuel priming pumps, dipsticks, and raw-water pump impellers. This low-speed generator is not engineered for dry land operation without raw seawater cooling, nor for high-frequency telecommunications equipment requiring pure sine wave harmonic distortion under 1 percent.

- 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.
