Refcomp SP4HN1500 SP4HN150E Reciprocating Chiller Compressor

Built with an integrated high-density suction strainer positioned at the gas inlet, this reciprocating chiller compressor captures solid particulate matter and system debris before refrigerant enters the motor chamber. The filter assembly is located on the outer side of the body housing, allowing simplified inspection, maintenance, and filter replacement without disassembling the main compressor housing.

Designed for precise thermal load control, this 4-cylinder reciprocating chiller compressor features a dual-stage energy regulation mechanism providing 100% and 50% capacity steps. The step-control feature allows system automation to modulate refrigerant displacement according to changing cooling demands, optimizing electrical energy efficiency during partial-load conditions.

Equipped with a RefComp-designed counterweighted crankshaft, precision connecting rods, and high-strength pistons, the internal drive mechanism suppresses mechanical vibration, gas pulsation, and operational noise. Heat-resistant bushings fitted to the connecting rod small ends reduce frictional wear under high-pressure cycles, ensuring long-term mechanical stability.
