Refcomp SP4HN1000 SP4HN100E Semi Hermetic Reciprocating Compressor

Designed with smooth internal gas channels, the SP4HN1000(SP4HN100E) semi hermetic reciprocating compressor minimizes suction pressure drops and internal clearance volume losses. Its compact housing integrates suction strainers, pressure sensors, and shut-off valves directly onto the crankcase frame, streamlining installation footprint in commercial refrigeration racks.

Engineered with custom counterweights and wear-resistant connecting rod small-end bushings, this 10HP semi hermetic reciprocating compressor achieves smooth dynamic balance during operation. The robust mechanical structure effectively absorbs rotational force, reduces mechanical wear, and extends running life in high-temperature operating conditions.

Equipped with step-wise energy regulation at 100% and 50%, the unit allows operators to adjust compressor output according to dynamic cooling loads. This variable output capability prevents short-cycling, optimizes energy consumption during partial-load demand, and improves system stability.

• Commercial Central HVAC: Suitable for commercial liquid chillers and roof-top air conditioning equipment.
• Cold Storage Rooms: Applied in medium and high-temperature cold storage facilities for fruit, vegetable, and food preservation.
• Industrial Fluid Cooling: Serves industrial process cooling systems requiring reliable output under varying thermal loads.
• Supermarket Multi-Compressor Racks: Operates as a core compressor unit in parallel supermarket display rack configurations.
