Paguro 22 EK Generator 22 kVA 20 kW 1500 RPM

Description

Heavy cast iron low-speed engine architecture anchors the Paguro 22 EK Marine Diesel Generator. Operating at a conservative 1,500 RPM, this four-cylinder 2.0-liter auxiliary diesel power plant delivers 20.0 kW continuous power with 22.0 kVA peak capacity. Built for displacement expedition yachts and commercial vessels, it maintains stable 50 Hz electrical power to run central chillers, hydraulic thruster power packs, and commercial galleys without high-RPM noise.

Heavy-duty compacted cast iron forms a rigid foundation to resist structural distortion during high-load marine cycles. The internal reciprocating train features a forged chrome-moly crankshaft, heavy-section connecting rods, and oil-jet cooled forged aluminum pistons. Technical specifications include an 88 mm bore, 90 mm stroke, 21.5:1 compression ratio, 6.5-quart oil capacity, and dry net weight of 880 lbs inside its acoustic capsule. Low engine speed minimizes mechanical wear.

Key Features of Paguro 22 EK

Commercial mariners buy Paguro 22 EK generator systems to provide substantial electrical capacity inside medium-displacement vessels. The low-speed 1,500 RPM block delivers unwavering torque reserves to handle heavy compressor starts without stalling.

• 20.0 kW continuous 230-volt single-phase output maintains heavy vessel electrical grids without alternator overheating.
• Four-pole low-speed 1,500 RPM alternator design maximizes component longevity during non-stop offshore voyages.
• Sealed acoustic housing keeps machinery noise restricted to 50 decibels inside adjoining accommodation spaces.
• Paguro 22 EK marine diesel generator electronic monitoring system triggers immediate engine shutdown upon fault detection.
• Oversized cupronickel heat exchanger maintains low engine coolant temperatures during full-load summer runs.
• 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.

Low Speed Alternator Dyno Capabilities

Turning at a steady 1,500 RPM, this four-stroke diesel delivers clean 50 Hz power across marine distribution panels. Continuous single-phase output yields 20.0 kW and 87 amps at 230 volts. Fuel burn averages 1.25 gallons per hour at 50 percent load and 2.20 gallons per hour at full continuous output. Lubrication galleries sustain 40 to 60 PSI hot pressure, keeping rod bearings protected under round-the-clock service during rough offshore navigation.

Engine Bed Machinery Clearances

Outer dimensions measure 1,150 mm long, 620 mm wide, and 740 mm high within its heavy sound enclosure. Four captive marine mounts detach engine harmonics from stringer frames. The 2.5-inch wet exhaust fitting requires direct fall to waterlock silencers, and side panels require six inches of technician working room.

Mandatory Service Protocol Safeguards

Vent the fuel injection circuit using the manual primer lever prior to first ignition. Fill the jacket freshwater loop to maximum levels to eliminate trapped air pockets. This generator package is not engineered for raw sea water block circulation, unvented bilges, or dry land installations.

• Drain factory break-in engine oil and renew oil filter elements after the first 50 operating hours.
• Inspect flexible raw water pump impellers and change primary fuel filter canisters every 200 operating hours.
• Clean heat exchanger raw water tubes and thread in fresh zinc sacrificial anodes every 12 months.

Factory Warranty Crate Inventory

Paguro covers this power plant with a 24-Month limited marine manufacturer warranty. The heavy freight crate includes the complete generator unit, sound isolation enclosure, digital remote display station, vibration isolator pads, certified load bank test sheets, and technical operator maintenance manuals.
