Refcomp SP4L1800 SP4L180E Semi Sealed Reciprocating Compressor

The SP4L1800(SP4L180E) incorporates an integrated INT6932 electronic protection module that provides continuous thermal monitoring of internal motor health. Interfaced directly with PTC thermistors embedded within the stator windings, the module immediately interrupts the control circuit during severe thermal overload, phase loss, or power supply fluctuations, shielding the motor against insulation degradation and electrical burnout.

Engineered to simplify field serviceability and equipment integration, the suction and discharge service valves feature 360° rotational positioning. This design allows installation crews and OEM rack builders to align refrigerant piping cleanly within tight multi-compressor frames without imparting mechanical stress on the valve flanges or requiring complex custom pipe bends.

Constructed with a heavy-duty cast-iron shell rated for working pressures up to 28 bar, the casing features optimized internal suction gas passages that minimize internal flow friction and suction superheat losses. The consolidated housing body integrates the suction strainer, service valves, safety relief valve, and temperature sensor ports into a single compact footprint, offering exceptional structural stability for industrial rack operations.
