Refcomp SP4HN2000 SP4HN200E Semi Sealed Reciprocating Compressor

The SP4HN2000 chiller reciprocating compressor features an optimized motor chamber that routes incoming suction gas directly across the stator windings before entering the compression cylinders. This flow path provides continuous motor cooling during heavy-duty operation while maintaining stable performance under maximum working pressures up to 28 bar.

Built with a counterweighted crankshaft, wear-resistant connecting rods, and high-strength pistons, this 20 HP chiller reciprocating compressor suppresses gas pulsation and structural vibration. Small-end connecting rod bushings minimize mechanical friction under high load cycles, supporting long service life in industrial and commercial installations.

To match fluctuating thermal loads, this 4-cylinder chiller reciprocating compressor incorporates two-stage step capacity regulation providing 50/100% displacement steps. This energy management feature allows system controllers to adjust cooling output according to real-time process demand, helping reduce electrical consumption during partial-load conditions.
