Refcomp SP4HF1200 SP4HF120E Semi-Hermetic Reciprocating Compressor

The SP4HF1200 semi hermetic compressor utilizes an internal gas routing design that directs suction gas from the inlet stop valve across the motor windings prior to compression. This layout provides effective motor cooling during continuous operation under working pressures up to 28 bar. An integrated internal safety valve bridges the high-pressure and low-pressure sides to prevent body pressure from exceeding safe thresholds.

Built with a counterweighted crankshaft, this 4-cylinder semi hermetic compressor minimizes gas pulsation and mechanical vibration during operation. The compressor features 100% and 50% energy regulation steps, enabling HVAC and refrigeration systems to adjust output according to variable thermal loads for efficient load matching.

Refrigerant Compatibility: R22, R134a, R407C, R404A, R507 (operates without changing mechanical parts)

Maximum Condensing Temperature: Up to 80°C with R134a

Minimum Evaporating Temperature: Down to -40°C with R22, R404A, and R507
