Refcomp SP6H4000 Reciprocating Semi Hermetic Compressor for Air Conditoning
Refcomp SP6H4000 reciprocating compressor
,semi hermetic air conditioning compressor
,refrigeration compressor with warranty
The SP6H4000 reciprocating semi hermetic compressor provides 3-stage energy modulation at 100%, 66%, and 33% capacity steps. This flexible load control allows commercial chillers to step down gas displacement smoothly during off-peak hours, cutting operational energy demand and preventing short-cycling.
Designed with an integrated INT6982 module, this 6-cylinder reciprocating semi hermetic compressor protects motor windings against phase imbalance and thermal overload. Incoming suction gas circulates through the motor cavity before compression, lowering internal temperatures during continuous high-ambient running.
Featuring custom dynamic counterweights and wear-resistant floating sleeve bearings, the robust dynamic system absorbs rotational stress. This mechanical design maintains low vibration and running noise across demanding industrial refrigeration duties.
- Commercial Central HVAC: Serves as a core compressor unit in high-capacity water chillers for commercial buildings and shopping malls.
- Industrial Process Cooling: Provides consistent fluid cooling for heavy industrial applications, including injection molding and chemical manufacturing.
- Cold Storage Warehousing: Suitable for medium and low-temperature agricultural storage facilities requiring uninterrupted 24/7 duty.
- Supermarket Multi-Compressor Racks: Integrates cleanly into parallel rack systems managing extensive refrigerated display case networks.

Ruifujie brings over 20 years of expertise to the refrigeration industry as a modern, large-scale manufacturer and supplier. We specialize in scroll, reciprocating, rotary, semi-hermetic, and screw compressors, along with cold storage equipment, quick-freezing systems, and ice-making machinery. Supporting comprehensive OEM and ODM customization, Ruifujie exports reliable cooling solutions globally across Russia, the United States, the United Kingdom, the United Arab Emirates, Saudi Arabia, and other key international markets.
It utilizes three-stage capacity regulation (100%, 66%, and 33%) to match shifting cooling loads, allowing the HVAC system to step down power consumption without cycling the motor unnecessarily.
Yes, its 6-cylinder layout distributes rotational torque evenly across multiple pistons, while dynamic crankshaft counterweights reduce mechanical shock and vibration under continuous heavy-duty operation.
Cold suction gas passes directly around the motor core to carry away winding heat, while an integrated INT6982 protection module actively monitors internal thermal levels and phase integrity.
In-stock sample units are ready for dispatch within 3 days, while standard commercial production orders ship within 10 to 15 working days.
Ruifujie provides a comprehensive 1-year product warranty along with complete technical guidance for all compressor purchases.
