The Refcomp SP2H0500 / SP2H050E is a 5HP (3.7kW) semi-hermetic reciprocating compressor engineered for reliable refrigeration performance. It combines a compact body, optimized gas flow paths, and integrated protection components to deliver stable operation across a range of refrigerants and operating conditions.
The SP2H0500 semi-hermetic reciprocating compressor features a 28 bar working pressure. Its optimized gas passages help reduce intake resistance and exhaust flow losses. The compact body integrates the filter, shut-off valve and temperature sensor.
RefComp's original crankshaft design supports smooth operation, low vibration and effective lubrication. This semi-hermetic piston compressor also features a wear-resistant bushing at the connecting rod's small end, helping reduce wear during operation.
The high-density suction filter removes impurities from refrigerant gas before they enter the compressor, helping protect the motor. Its external mounting makes inspection and replacement more convenient.
The integrated INT69B2 protection module provides motor protection against burnout, adding an important safety component to the compressor's electrical protection system.

To assess whether this semi-hermetic reciprocating compressor is suitable, provide the required cooling capacity, refrigerant, evaporating and condensing temperatures, power supply and application details. This reciprocating refrigeration compressor should be selected according to the actual operating conditions.
The standard motor specifications list Δ230V/3-phase/50Hz and Y400V/3-phase/50Hz. Confirm the available site power supply and the corresponding motor connection before commissioning.
Before commissioning the semi-hermetic reciprocating compressor, check the refrigerant piping connections, system cleanliness, oil charge and motor protection wiring. Make sure the selected motor connection matches the available power supply.
Check the power supply, phase condition, motor wiring and operating conditions. Identify and correct the cause of the protection trip before restarting the compressor.
