Refcomp SP4LN0600 SP4LN060E Semi Hermetic Reciprocating Chiller Compressor

The SP4LN0600(SP4LN060E) features integrated solenoid-driven energy regulation, allowing the 4-cylinder compression block to step down from 100% full capacity to 50% partial load. This flexibility enables process chillers and multi-compressor racks to match fluctuating cooling demands dynamically, reducing electrical power consumption and preventing rapid compressor cycling under low thermal loads.

Built for demanding 6 HP industrial and commercial chilling duty, the heavy-duty stator motor supports PW starting configurations across 400V/50Hz and 460V/60Hz power grids. By staging power delivery, starting inrush current is limited to 43A , protecting electrical contactors and stabilizing site voltage. Continuous suction gas flow across motor windings provides effective thermal dissipation. 

Designed for straightforward jobsite maintenance, the compressor incorporates a high-density mesh suction filter mounted directly within an externally accessible housing port. This strainer effectively captures solid debris, scale, and circuit contaminants before they enter the compression chamber, safeguarding valve plates and cylinder walls from mechanical damage.
