Product Description
Refcomp SP6L3000 SP4L300E Low-Temperature Reciprocating Chiller Compressor
Product Overview
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.

Frequently Asked Questions
How does the 6-cylinder balanced architecture minimize vibration in large chiller skids?
The optimized mass balance across 6 cylinders offsets reciprocating inertial forces, significantly reducing structural vibration and pipeline stress on chiller frames.
What is the purpose of the 4.2 dm³ oil sump capacity during continuous full-load operation?
The generous oil reservoir volume ensures stable lubrication feed via the internal gear pump, preventing oil starvation during rapid load transitions and capacity modulation.
How does the Part-Winding (PW) motor configuration protect electrical infrastructure for a 30 HP compressor?
Part-Winding starting splits the motor winding sequence during startup, limiting initial electrical inrush to 150 A instead of 250 A (DOL) to protect facility circuit breakers.
What type of routine inspection is recommended for the integrated thermal protection sensors?
Technicians should periodically verify continuity and calibration of the electronic protection module wiring to ensure timely shutdown during abnormal winding temperature spikes.
What documentation is provided for customs clearance on international chiller component shipments?
Each shipment includes commercial invoices, packing lists, bills of lading, CE compliance certificates, and factory pressure test inspection reports.
