Description

Sustain commercial vessel three-phase balance using the Thornycroft TRGT-40 Marine Generator Package. Displacing 3.8 liters across four turbocharged cylinders, this high-output marine diesel auxiliary engine outputs 31.2 kW continuous three-phase power with 39.0 kVA peak capacity at 1,500 RPM. Complete freshwater heat exchanger cooling inside an acoustic capsule isolates raw sea water from engine water jackets, sustaining industrial refrigeration plants and high-pressure deck machinery.

A turbocharged cast iron four-cylinder block provides structural stiffness under high continuous combustion boost pressures. The internal rotating group incorporates a forged alloy steel crankshaft, reinforced forged connecting rods, and oil-cooled aluminum pistons. Engine geometry presents a 100 mm bore, 120 mm stroke, 17.5:1 compression ratio, 12.0-quart oil capacity, and total dry weight of 1,320 lbs inside its sound shield. Splayed main bearing caps reinforce lower case rigidity under heavy loads.

Key Features of Thornycroft TRGT-40

Commercial mariners buy Thornycroft TRGT-40 generator packages to deliver balanced three-phase auxiliary current across offshore trawlers and workboats. This 50 Hz power unit outputs balanced 400-volt alternating current to eliminate phase imbalances across heavy machinery spaces.

  • 31.2 kW continuous 400-volt three-phase output supports heavy induction motor starts without voltage sag.
  • Water-cooled turbocharger boosts low-end torque reserves to manage sudden electrical motor startup spikes.
  • Asynchronous brushless alternator design eliminates slip rings while delivering high electrical efficiency.
  • Sealed acoustic housing keeps machinery noise restricted to 56 decibels inside adjoining accommodation spaces.
  • TRGT-40 marine generator package electronic monitoring system triggers immediate engine shutdown upon fault detection.
  • Complete liquid cooling circulates freshwater through both the diesel engine and alternator winding jackets.
  • Water-cooled cast iron exhaust elbow isolates heat radiation from composite fiberglass engine beds.
  • Central service layout places dipsticks, oil filters, and the sea water pump behind one quick-release door.

Three Phase Alternator Load Performance

Operating at an exact 1,500 RPM governing point, this four-stroke diesel maintains steady 50 Hz current standards. Full electrical output yields 31.2 kW (39.0 kVA at 0.8 power factor) across 400-volt lines. Measured fuel burn records 2.15 gallons per hour at 50 percent load and 3.95 gallons per hour at full continuous rating. The pressurized lubrication circuit maintains 40 to 65 PSI hot oil pressure, shielding critical crankshaft journals.

Engine Bed Machinery Clearances

Outer dimensions measure 1,490 mm long, 720 mm wide, and 830 mm high within its heavy sound enclosure. Four captive marine mounts detach engine harmonics from stringer frames. The 3-inch wet exhaust fitting requires direct fall to waterlock silencers, and side panels require six inches of technician working room.

Scheduled Marine Service Rules

Operate the fuel feed priming arm to evacuate air from diesel filter bowls before initial engine start. Maintain full expansion bottle coolant levels to prevent dry heat cycles. This marine unit is not engineered for raw sea water block cooling, open deck installations, or unvented gasoline holds.

  • Extract factory run-in oil and renew full-flow filter elements after the initial 50 hours of operation.
  • Check raw water pump impeller flexibility and clean fuel separator bowls every 200 running hours.
  • Descale heat exchanger core tubes and thread in fresh zinc protection plugs every 12 months.
