Lombardini LMG18000 16kW 20kVA 3-Phase 400V/50Hz Marine Diesel Generator

Description

Meet commercial vessel three-phase electrical standards with the Lombardini LMG18000 Three-Phase Marine Generator. Displacing 1.372 liters across four in-line cylinders, this marine diesel power plant outputs 16.0 kW continuous three-phase power with 20.0 kVA peak capacity at 3,000 RPM. Built with a 400-volt 50 Hz winding, it sustains commercial refrigeration units, hydraulic pack pumps, and central chillers without phase imbalance.

Thick-wall cast iron block metallurgy deadens mechanical combustion rumble within confined marine machinery spaces. The rotating group incorporates a forged alloy steel crankshaft, forged connecting rods, and oil-cooled aluminum pistons. Engine geometry measures a 72 mm cylinder bore, 84 mm stroke, 22.8:1 compression ratio, 4.0-quart oil sump capacity, and dry net weight of 507 lbs inside its sound shield. Splayed main bearing caps reinforce lower case rigidity under heavy loads.

Key Features of Lombardini LMG18000

Commercial mariners buy Lombardini LMG18000 generator packages to achieve dependable three-phase power inside working vessel hulls. This 50 Hz power unit outputs balanced 400-volt alternating current to eliminate phase imbalances across heavy machinery spaces.

• 16.0 kW continuous 400-volt three-phase output supports heavy induction motor starts without voltage sag.
• Four-pole brushless alternator design uses solid-state regulation to hold line voltage variation within one percent.
• Heavy sound attenuation housing suppresses internal combustion noise down to 54 decibels at seven meters distance.
• LMG18000 marine diesel generator electronic governor maintains precise 50 Hz frequency under sudden electrical step loads.
• Cupronickel tube-and-shell heat exchanger prevents raw seawater from contacting internal cast iron water jackets.
• Automatic engine protection network halts operation upon detection of high exhaust heat or low oil pressure.
• Starboard maintenance layout clusters oil filters, fuel filters, and water pump behind one panel.

Three Phase Alternator Output Verification

Turning at a governed 3,000 RPM, this four-stroke diesel delivers clean 50 Hz electrical power across marine switchboards. Continuous three-phase output yields 16.0 kW (20.0 kVA at 0.8 power factor) across 400-volt circuits. Measured fuel burn records 0.95 gallons per hour at half load and 1.70 gallons per hour at full continuous rating. Pressurized internal lubrication galleries sustain 35 to 55 PSI hot oil pressure, shielding critical crankshaft and camshaft journals from friction during non-stop offshore commercial operations.

Sound Shield Hull Clearance Boundaries

The sound shield capsule measures 860 mm long, 520 mm wide, and 610 mm high, dropping between structural inboard stringers. Four captive rubber isolators prevent mechanical vibration transmission to hull frames. A 2-inch water-cooled wet exhaust mixer drops cooled gases overboard, requiring five inches of starboard clearance for technician access.

Diesel Generator Service Maintenance Rules

Purge air from fuel injection passages using the manual primer arm before engaging the electric starter. Fill freshwater cooling loops with approved marine coolant to prevent localized hot spots. This unit is not engineered for dry land exhaust operation, raw sea water block circulation, or unventilated bilge spaces.

• Drain factory break-in lube oil and install fresh filter elements after the first 50 operating hours.
• Inspect flexible raw water pump impellers and drain fuel sediment bowls every 200 running hours.
• Clean cupronickel heat exchanger tubes and replace sacrificial zinc anode plugs every 12 months.

Marine Warranty Pack Manifest

Lombardini supports this generator with a 24-Month limited commercial marine warranty. The wooden freight crate contains the complete generator unit, sound attenuation enclosure, remote digital control panel, flexible fuel line kit, factory load test printout, and technical operator service documentation binder.
