Southeastern Power Products SEP-8.5 Marine Diesel Generator – Radiator Cooled

During dry-dock commercial vessel refit operations, the Southeastern Power Products SEP-8.5 Marine Generator keeps galley equipment and power tools operating without needing sea water cooling. Delivering 8.5 kW continuous power and 10.0 kVA surge output at 120V and 240V 60Hz, this radiator-cooled diesel plant sustains walk-in coolers, battery chargers, and high-intensity work lamps.

An industrial Kubota three-cylinder diesel engine drives a heavy four-pole synchronous alternator, connected to a heavy-duty copper-brass radiator core and pusher fan assembly. Stator assemblies incorporate 100 percent copper windings with Class H marine varnish to prevent insulation degradation from ocean humidity. Weighing 445 lbs dry, the generator housing measures 35.0 inches long by 20.5 inches wide by 25.5 inches high.

Key Features of Southeastern Power Products SEP-8.5

Commercial contractors who buy Southeastern Power Products SEP-8.5 marine generator hardware gain radiator-cooled commercial power equipment built for dry vessel areas and marine workboats. The integrated cooling radiator eliminates seawater intake maintenance, allowing continuous operation when vessels sit on shipyard blocks or traverse muddy shallows.

- 8.5 kW continuous single-phase power sustains large luxury yacht galleys and laundry equipment simultaneously.
- 10.0 kVA peak surge capacity absorbs heavy locked-rotor amperage from large chiller compressor motors.
- Self-contained radiator cooling system eliminates raw-water intake seacocks, hoses, and raw impeller failures.
- Kubota three-cylinder diesel block provides smooth mechanical balance and low rotational vibration.
- SEP-8.5 radiator cooled genset enables continuous auxiliary power production while vessels rest in shipyard dry-docks.
- Brushless four-pole alternator design eliminates maintenance associated with slip rings and carbon brushes.
- Internal elastomeric isolation mounts decouple low-frequency diesel vibration from vessel hull structures.
- Safety shutdown sensors trigger automatic stops upon high coolant heat, low oil pressure, or exhaust flow loss.

Voltage Sag Limits Sound Decibel Ratings

Emitting 63 dB(A) at 23 feet, this radiator-cooled generator maintains stable electrical parameters in ventilated deckhouses and workboat machinery flats. An internal electronic automatic voltage regulator maintains output voltage within 2 percent of 120V and 240V standards at 60 Hz during sudden 5 kW electrical step loads. Diesel fuel consumption measures 0.58 GPH at 50 percent load, providing high operational efficiency.

Deck Flat Mounting Ventilation Clearances

Secure the mounting base to structural steel beams, ensuring at least 18 inches of unimpeded clearance in front of the radiator core to expel hot air outside. Connect dry exhaust piping to a stainless steel marine muffler insulated with thermal blankets. Grounding circuits link to vessel bonding buses through isolated ground returns to prevent galvanic zinc loss.

Service Handling Periodic Maintenance Protocols

Single-side maintenance engineering places all primary checkpoints on one accessible face for rapid routine inspections. This radiator-cooled marine generator is not engineered for unventilated lower bilges, raw-water wet exhaust piping, or hazardous atmospheres containing flammable gasoline vapors.

- Inspect radiator coolant expansion recovery tanks and check oil before each shift.
- Renew engine oil and replace primary fuel filters every 100 runtime hours.
- Inspect cooling fan belts and clear debris from radiator cores every 250 runtime hours.
