Refcomp SP6H3700 SP6H370E Semi Hermetic Reciprocating Refrigeration Compressor

The SP6H3700(SP6H370E) semi hermetic reciprocating refrigeration compressor includes an integrated high-density suction strainer positioned at the main gas inlet to trap solid particles, scale, and system debris before refrigerant enters the motor chamber. Fitted on the outer end of the compressor housing, the filter screen allows fast inspection, routine cleaning, and replacement without requiring main body teardown.

Built to handle working pressures up to 28 bar, this 6-cylinder semi hermetic reciprocating refrigeration compressor features an optimized internal suction channel layout that minimizes pressure drop and flow resistance. The compact cast body routes cool suction gas directly across internal passages to cool the motor windings while integrating suction filters, shut-off valves, and thermal sensors into a unified, space-saving shell.

Equipped with heavy-duty sliding sleeve bearings (bushings) and precision thrust washer sets, the drive mechanism prevents axial and radial wear under heavy continuous loads. Supported by a forced lubrication circuit and effective thermal dissipation, the bearing assembly operates with low mechanical noise and delivers a design service life of 50,000 to 80,000 operational hours.
