Refcomp SP4L2200 SP4L220E Semi Hermetic Reciprocating Refrigeration Compressor

The SP4L2200(SP4L220E) features a heavy-duty, high-density mesh suction filter built directly inside the intake manifold assembly. Positioned within an easily accessible external casing port, this strainer captures copper scale, pipe debris, and system contaminants before they reach the valve plates or piston chambers, safeguarding critical internal components against mechanical wear and preserving volumetric efficiency.

Engineered for smooth field installation and versatile pipe routing, both the suction and discharge service valves support full 360° rotation. This allows OEM rack manufacturers and installation technicians to connect suction and liquid lines cleanly from any angle, reducing pipe fitting stress on the cast-iron housing and speeding up multi-compressor rack assembly.

Built to withstand demanding continuous freezing operations, the inner drive assembly utilizes precision floating sleeve bearings paired with high-load thrust washers. Custom-engineered internal oil channels maintain a continuous protective oil film over all friction surfaces, reducing bearing wear during high-load startups and extending overall mechanical operating life up to 50000 to 80000 hours.
