Product Description
Refcomp SP6L2700 SP4L270E Reciprocating Chiller Compressor for Commercial Air Conditioning
Product Description
3-Step Solenoid Capacity Modulation (100%, 66%, 33%)
Engineered for precise load management in process chillers and commercial refrigeration, this 6-cylinder reciprocating chiller compressor features a solenoid-activated 3-stage capacity control system offering 100%, 66%, and 33% output steps. By matching refrigerant displacement dynamically to fluctuating thermal loads, the compressor prevents excessive motor restarts, stabilizes chiller supply liquid temperatures, and optimizes part-load energy efficiency.

Suction Gas-Cooled Multi-Refrigerant Motor
Built with internal flow channels that pass cool returning suction gas directly across the motor housing, the integrated motor maintains low winding operating temperatures under severe low-evaporating conditions. Supporting Part-Winding (PW) low-inrush starting, the custom motor ensures stable multi-refrigerant operation with R22, R407C, R134a, R404A, and R507.

High-Precision Floating Sleeve Bearing Assembly
Utilizing a heavy-duty 6-cylinder drive train equipped with floating sleeve bearings and precision thrust washers, this reciprocating chiller compressor dynamically distributes oil film pressure to eliminate shaft friction and radial wear. The dynamically balanced crankshaft with counterweights dampens gas pulsation and structural vibration, supporting an extended mechanical design life of 50,000 to 80,000 operating hours.

Integrated Outer-Accessible Filtration & Overpressure Safety
To safeguard internal cylinder valves in heavy industrial cooling loops, the unit incorporates an outer-accessible high-density suction filter screen that traps system debris before compression. System protection 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.

Frequently Asked Questions
Q1: How does the 3-step capacity modulation (100%, 66%, 33%) benefit multi-circuit liquid chillers?
A1: It allows individual compressors in multi-circuit chiller skids to fine-tune displacement according to leaving water temperature sensors, reducing power draw during low ambient or low occupancy hours.
Q2: Why is the outer-accessible suction filter advantageous for routine maintenance in industrial plants?
A2: Service technicians can access, inspect, and flush the internal filter screen via the external casing end plate without unbolting or re-welding main suction line connections.
Q3: How does the internal differential pressure relief valve operate during abnormal discharge pressure spikes?
A3: If discharge pressure reaches critical thresholds, the internal valve opens to vent high-pressure gas back into the low-pressure suction chamber, protecting the casing integrity.
Q4: What starting method should be specified to minimize voltage drop on industrial electrical grids?
A4: Utilizing Part-Winding startup significantly reduces peak inrush current, preventing voltage sags across local distribution panels.
Q5: What standard export packaging is utilized for heavy 6-cylinder compressors?
A5: Compressors are bolted directly to reinforced heavy-duty wooden skids, vacuum-sealed with desiccants, and shipped with a factory holding gas charge in compliance with international freight standards.
