Refcomp SP4LF0800 SP4LF080E Reciprocating Semi Hermetic Compressor

The SP4LF0800(SP4LF080E) is equipped with an integrated INT6932 electronic protection module that monitors motor winding temperatures and operating parameters in real time. Embedded PTC sensors inside the stator windings instantly trip the control circuit during thermal overload, single-phasing, locked rotor conditions, or voltage imbalances, preventing catastrophic motor failure and extending operational reliability in demanding commercial refrigeration environments.

Engineered for optimal thermal control, cold suction refrigerant vapor enters through the rear casing and passes directly across the stator and rotor before entering the compression chambers. This internal gas-flow channel continuously dissipates motor heat, enabling stable operation under low evaporating temperatures without requiring complex external liquid injection or auxiliary fan cooling accessories.

Designed to streamline rack construction and piping installation, the suction and discharge service shut-off valves feature full 360° rotational adjustment. An internal safety relief valve positioned between the suction and discharge chambers automatically equalizes extreme pressure differentials, safeguarding the heavy-duty cast-iron body against over-pressurization during abnormal operational spikes.
