Southeastern Power Products KK4-30.0 Marine Diesel Generator – Keel Cooled

Description

Power heavy commercial shrimp boat deck winches with the Southeastern Power Products KK4-30.0 Marine Generator, delivering industrial keel-cooled reliability for high-tonnage marine work. Operating at 1800 RPM, this heavy plant produces 30.0 kW continuous output and 36.0 kVA surge power at 120V and 240V 60Hz, running multi-ton brine freeze tanks, watermakers, and commercial galley appliances on extended voyages.

A four-cylinder 3318cc Kubota V3300 diesel engine powers a four-pole brushless synchronous alternator, secured to a heavy-gauge steel channel frame with elastomeric vibration dampers. Copper windings coated with Class H thermal varnish ensure maximum electrical conductivity without heat saturation. Weighing 960 lbs dry, the generator housing measures 49.5 inches long by 25.5 inches wide by 30.0 inches high.

Key Features of Southeastern Power Products KK4-30.0

Shipyard directors who buy Southeastern Power Products KK4-30.0 marine generator units gain keel-cooled commercial power equipment capable of powering heavy-duty maritime machinery. Its Kubota diesel engine maintains rated electrical wattage continuously without thermal derating in muddy delta waters where raw-water cooling systems fail.

• 30.0 kW continuous high-voltage electrical capacity powers commercial chillers, elevators, and large exhaust hoods.
• 36.0 kVA surge rating starts large inductive watermaker pumps and hydraulic bow thrusters without breaker trips.
• Keel-cooled closed circuit cooling eliminates raw-water pumps, sea strainers, and heat exchanger acid flushing.
• Kubota four-cylinder diesel engine delivers steady mechanical torque under sudden maximum electrical loads.
• KK4-30.0 commercial marine construction utilizes cast-iron cylinder liners for extended engine operational life.
• Brushless synchronous alternator eliminates carbon brushes and slip rings to minimize maintenance requirements.
• Heavy-duty structural channel base incorporates captive spring isolators to damp torsional engine pulses.
• Emergency automatic shutdown sensors stop fuel delivery upon high engine coolant temperature or low oil pressure.

Voltage Sag Limits Sound Decibel Ratings

Emitting 59 dB(A) at 23 feet inside an acoustic sound enclosure, this diesel generator prevents noise fatigue across crew rest quarters. An integrated automatic voltage control maintains output voltage within 1.5 percent of 120V and 240V standards, preventing current drops during heavy compressor motor startup cycles. Operating at half load, the diesel engine burns 1.95 GPH, providing dependable and economical electrical power.

Keel Cooler Plumbing Base Fitment

Mount the heavy steel frame directly onto structural hull engine beds using fitted marine bolts, maintaining 20 inches of service clearance around all sides. Plumb closed-loop cooling lines directly to external keel cooler channels welded to the vessel bottom. The electrical panel utilizes an isolated neutral and ground return to block hull corrosion.

Commercial Usability Scheduled Service Intervals

Heavy steel lifting brackets welded to the engine cylinder head permit crane rigging into deep commercial vessel holds. This keel-cooled marine generator is not engineered for wet exhaust marine installations lacking exterior keel coolers, nor for gasoline vapor spaces lacking spark-proof ratings.

• Inspect closed-loop coolant header tank levels and oil dipsticks before each shift.
• Drain engine oil and install fresh spin-on oil filter elements every 200 runtime hours.
• Check valve lash clearances and test engine safety shutdown circuits every 500 runtime hours.
