Refcomp SP4H3000 SP4H300E Semi Hermetic Reciprocating Refrigeration Compressor

The semi hermetic reciprocating refrigeration compressor (SP4H3000/SP4H300E) is built for medium-to-high temperature commercial refrigeration, large liquid chillers, and industrial climate control applications. Operating with a 4-cylinder layout, it delivers a displacement of 86.1 m³/h at 50Hz (103.3 m³/h at 60Hz) driven by a 30 HP (22.4 kW) motor, ensuring continuous high volumetric efficiency under heavy continuous cooling loads.

• 360° Rotatable Shut-off Valves for Easy Piping: Equipped with suction and discharge shut-off valves that feature a 360° rotatable flange design, this compressor offers exceptional installation flexibility. Operating engineers can quickly adjust valve angles to align with existing plant piping, reducing stress on connection points and streamlining routine field servicing.
• Integrated High-Density Suction Filter: Featuring a built-in high-density suction filter element, the unit intercepts scale, welding slag, and foreign particulates before refrigerant flows into the motor chamber. Mounted externally on the suction flange, the filter allows for rapid inspection and maintenance without dismantling the main compressor casing.
• Hydrodynamic Sliding Bearings for Long Service Life: Utilizing babbitt-lined hydrodynamic sliding bearings paired with axial thrust washers, the internal drive mechanism evenly distributes load forces across all contact surfaces. Supported by precision oil supply channels, the heavy-duty bearing configuration achieves a design service life of 60,000 to 80,000 operating hours.

• Large Commercial Cold Storage Logistics: Provides high-tonnage cooling for regional food distribution centers, walk-in cold rooms, and agricultural processing hubs.
• Commercial HVAC & Packaged Liquid Chillers: Ideal for air-cooled and water-cooled liquid chiller plants delivering climate control to commercial buildings.
• Industrial Process Cooling: Delivers reliable fluid temperature regulation for chemical processing, beverage production, and commercial manufacturing lines.

A1: The compressor is equipped with suction and discharge shut-off valves featuring a 360° rotatable flange design. Engineers can easily adjust the valve orientation to align with existing site piping, eliminating extra pipe bends and stress on copper lines.

A2: An integrated high-density suction filter is built into the external suction flange. It traps copper chips, scale, and welding slag before gas enters the motor, and can be inspected or cleaned directly without opening the compressor casing.

A3: The unit utilizes babbitt-lined hydrodynamic sliding bearings paired with axial thrust washers and optimized lubrication channels, delivering a design service life of 60,000 to 80,000 operating hours under heavy continuous duty.

A4: In-stock sample units ship within 3 business days, while standard mass production orders take 10 to 15 working days.

A5: All compressors include a 1-year standard factory warranty. Orders are fulfilled under FOB Shenzhen or EXW terms, with payment accepted via TT or Western Union in USD.
