Refcomp SP4LF1000 SP4LF100E Semi Sealed Compressor For Cold Room

Equipped with an internal high-density suction gas filter positioned directly at the intake manifold, the SP4LF1000 effectively traps solid debris, metal shavings, and piping contaminants before they reach the compression cylinders. This internal filtration setup safeguards the valve plates, pistons, and motor windings from mechanical scoring, maintaining long-term volumetric efficiency and reducing maintenance overhead in complex low-temperature systems.

Designed for heavy-duty 10 HP commercial refrigeration duty, the SP4LF1000 supports Part-Winding starting configurations. By energizing motor windings in stages, this starting mechanism cuts initial peak current spikes down to 71A, mitigating line voltage drops on jobsite grids, extending contactor service life, and ensuring smooth motor acceleration under heavy load.

Engineered to withstand working pressures up to 28 bar, the heavy-duty cast-iron housing consolidates internal gas channels, oil sight glass ports, pressure relief valves, and crankcase heater pockets into a single compact chassis. The streamlined internal passage design minimizes suction gas superheat losses while providing high structural rigidity against mechanical shock in multi-compressor rack frames.
