The Refcomp SP2L0500 / SP2L050E is a 5HP (3.7kW) semi-hermetically sealed reciprocating compressor engineered for dependable refrigeration performance. Its mechanical design, bearing arrangement and integrated protection systems work together to support stable operation, reduced wear and long service life in demanding cooling applications.
The SP2L0500 semi-hermetically sealed compressor features RefComp's specially developed crankshaft design, supporting smooth mechanical movement, effective lubrication and reduced vibration. A wear-resistant bushing at the connecting rod's small end helps minimize friction and mechanical wear, contributing to reliable operation.
The combination of sliding and thrust bearings accommodates both radial and axial loads during operation. High-precision fitting and effective lubrication help reduce friction and operating noise, supporting smoother movement and reducing wear on critical mechanical components.
The internal safety valve connects the high- and low-pressure sides, providing protection against abnormal internal pressure conditions. Its precise opening and automatic reset help maintain safe compressor operation and reduce the risk associated with excessive pressure.
The integrated INT69B2 protection module helps protect the motor against burnout. This dedicated protection system provides an additional safeguard against abnormal operating conditions, helping reduce the risk of motor damage and unexpected equipment downtime.

When selecting a semi-hermetically sealed compressor, provide the required cooling capacity, refrigerant, evaporating and condensing temperatures, ambient conditions and power supply. As a low-temperature reciprocating compressor, the SP2L0500 should be matched to the actual system operating conditions.
Check the foundation, refrigerant piping connections, electrical wiring and crankcase heater before commissioning. Proper installation helps minimize unnecessary vibration and supports stable operation of the semi-hermetic reciprocating compressor.
The protection module monitors the motor protection circuit and helps prevent motor burnout under abnormal conditions. If protection is triggered, identify the underlying electrical or operating problem before restarting the compressor.
Regularly inspect lubrication conditions, operating noise, vibration and safety protection components. Keeping the mechanical assembly properly lubricated and identifying abnormal conditions early helps reduce unnecessary component wear.
