Refcomp SP4LN1200 SP4LN120E Semi-Hermetic Type Compressor For AC Unit

Designed for seamless jobsite integration, the SP4LN1200(SP4LN120E) features heavy-duty suction and discharge shut-off valves capable of 360° rotation. This flexibility allows mechanical contractors and OEM rack builders to align piping connections in tight multi-compressor frames without inducing mechanical stress on the cast-iron casing, simplifying pipe routing and reducing installation labor hours.

Driven by a high-efficiency 12 HP motor, the SP4LN1200 supports PW starting configurations across 400V/50Hz and 460V/60Hz industrial power supplies. Staging the power energization reduces initial starting inrush current to 75A, preventing severe voltage drops, stabilizing local electrical grids, and extending contactor component life.

To protect critical internal moving parts against circuit contaminants, the compressor incorporates a high-density mesh suction filter directly inside the intake manifold. Positioned within an easily accessible external casing port, the filter captures copper shavings, scale, and foreign debris before they enter the cylinder chambers, maintaining valve plate seal integrity and long-term volumetric performance.
