The Refcomp SP2H0900 (SP2H090E) is a 9HP / 6.6KW semi-hermetic compressor engineered for cold storage and commercial refrigeration applications. It combines integrated safety protection, a balanced crankshaft and piston mechanism, precision bearing arrangement, and the INT69B2 motor protection module to deliver stable, reliable long-term operation.
The SP2H0900 semi-hermetic compressor features an internal safety valve connecting the high- and low-pressure sides. Its precise opening and timely reset help keep internal pressure within the designed safety range, providing additional protection against abnormal pressure conditions.
The RefComp 9HP semi-hermetic compressor uses a specially developed crankshaft design that balances the moving components for smoother operation, reduced vibration and effective lubrication. The wear-resistant bushing at the connecting rod's small end helps reduce mechanical wear and supports long-term operating reliability.
A combination of sliding and thrust bearings handles radial and axial loads within the compressor. High-precision fitting and effective lubrication help reduce friction and operating noise, supporting stable mechanical performance.
The built-in INT69B2 protection module helps protect the motor against burnout. This integrated electrical safeguard provides an additional layer of protection, helping improve operational safety and reduce the risk of motor damage.

When selecting a semi-hermetic compressor, consider the required cooling capacity, refrigerant, evaporating and condensing temperatures, ambient conditions and power supply. These details help verify whether the compressor's operating range matches your system requirements.
The RefComp SP-series support R22, R407C, R134a, R404A and R507 as refrigerant options. Please confirm the specific model configuration and operating conditions before ordering.
Check the refrigerant piping connections, system cleanliness, lubrication condition, crankcase heater wiring and motor protection circuit. The electrical connection and starting arrangement should also match the site power supply.
Inspect the power supply, phase condition, motor wiring and operating conditions to identify the cause. Correct the underlying problem before restarting the semi-hermetic compressor rather than repeatedly resetting the protection module.
