3-Step Solenoid Capacity Modulation (100%, 66%, 33%)
Engineered for high-capacity industrial chillers and large commercial refrigeration systems, this 6-cylinder chiller reciprocating compressor features a solenoid-actuated 3-stage capacity regulation system supporting 100%, 66%, and 33% output steps. By adjusting refrigerant displacement dynamically to match varying thermal loads, the system prevents excessive motor cycling, stabilizes chilled liquid supply temperatures, and optimizes part-load energy efficiency.
Optimized 6-Cylinder Mass Balance Design
Built on a robust 6-cylinder platform with a dynamically balanced crankshaft and integrated counterweights, this chiller reciprocating compressor delivers exceptionally smooth, low-vibration running characteristics. The symmetrical cylinder layout dampens gas pressure pulsations and minimizes structural noise during continuous heavy-duty operation.
Suction Gas-Cooled Multi-Refrigerant Motor
Featuring internal flow channels that route cool returning suction gas directly across the motor housing, the integrated motor maintains low operating temperatures under severe low-evaporating conditions. The motor supports dual-frequency power supplies (400V/50Hz and 460V/60Hz PW) and ensures reliable performance with R22, R407C, R134a, R404A, and R507.
Integrated Filtration & Overpressure Protection
To protect internal cylinder valves and precision components from system contaminants, the unit incorporates an outer-accessible high-density suction filter screen. Operational safety is further reinforced by an internal differential safety valve that automatically relieves excess pressure from the discharge side back into the suction chamber during abnormal pressure surges.
