Three-Stage Capacity Control
The SP8L5000 semi-hermetic reciprocating refrigeration compressor features three-stage capacity regulation, allowing cooling output to adjust according to changing refrigeration loads. This improves load matching, reduces unnecessary full-load operation, and provides greater flexibility under varying operating conditions.
-
Integrated Crankcase Heating
The built-in crankcase heater helps maintain suitable oil temperature during compressor shutdown, reducing the risk of refrigerant migration into the lubricating oil. This supports better lubrication conditions and more reliable compressor startup in low-temperature refrigeration applications.
-
Reliable Motor Protection
The integrated INT69B2 protection module provides protection against motor burnout, helping safeguard critical electrical components. This additional protection supports dependable operation of the 8-cylinder compressor in demanding refrigeration systems.
-
High-Density Suction Filtration
The externally mounted high-density suction filter captures impurities from refrigerant gas before they enter the compressor, helping protect internal mechanical components. Its accessible installation also makes inspection and replacement more convenient during routine maintenance.

The SP8L5000 is a 50 HP reciprocating compressor designed for low-temperature refrigeration applications. Selection should consider the required cooling capacity, refrigerant, evaporating and condensing temperatures, power supply, and actual operating conditions.
R22 is among the refrigerants applicable to the RefComp SPL series. An R22 semi-hermetic compressor configuration can be considered for compatible low-temperature applications, with system conditions and the selected motor configuration confirmed during technical selection.
Check the power supply, motor wiring, starting arrangement, refrigerant piping, and lubrication system. The crankcase heater and motor protection module should also be correctly connected according to the manufacturer's installation instructions.
Regularly inspect the suction filter, lubricating oil condition, electrical connections, and crankcase heater. If abnormal noise, vibration, or operating changes occur, investigate the cause before continuing normal operation.
