The RefComp SP8H6000 / SP8H600E is a 60 HP semi-hermetic reciprocating chiller compressor engineered for HVAC and refrigeration systems. It combines three-stage capacity control, a high-temperature compressor design, a refined crankshaft and connecting-rod structure, and partial-winding motor starting to deliver dependable performance across demanding operating conditions.
The SP8H6000 reciprocating chiller compressor features three-stage capacity control, allowing compressor output to adjust according to changing cooling demand. This helps match refrigeration capacity to actual system loads and avoids unnecessary full-load operation during periods of lower demand.
As a high-temperature reciprocating compressor in the RefComp SP H series, the SP8H6000 features optimized internal gas passages that reduce intake resistance and exhaust flow losses. This supports smoother refrigerant flow and helps the compressor operate under its intended high-temperature refrigeration conditions.
RefComp's crankshaft design promotes smooth mechanical movement, effective lubrication and reduced vibration. The wear-resistant bushing at the connecting rod's small end helps minimize friction and mechanical wear, supporting reliable operation over extended service periods.
The partial-winding starting arrangement helps reduce motor starting current compared with direct-on-line starting. This reduces the initial electrical demand on the power supply and makes it easier to coordinate compressor startup with the refrigeration system's electrical configuration.

When selecting a 60 HP compressor for a chiller, provide the required cooling capacity, refrigerant, evaporating and condensing temperatures, ambient conditions and power supply. These details help verify whether the reciprocating chiller compressor matches your actual operating requirements.
The available capacity steps allow the compressor to respond to different cooling loads instead of continuously operating at full capacity. This provides greater flexibility when system demand changes throughout the operating cycle.
Check that the site power supply matches the specified motor configuration and that the partial-winding starter, phase sequence and electrical protection are correctly arranged. Proper electrical matching helps avoid starting problems and protects the motor during operation.
For a semi-hermetic reciprocating compressor, regularly monitor lubrication condition, abnormal noise, vibration and refrigerant leakage. If the reciprocating chiller compressor experiences repeated protection trips or unusual operating conditions, identify the underlying cause before restarting.
