Refcomp SP4LF1200 SP4LF120E Low-Temperature Chiller Reciprocating Compressor
Product Overview
Designed for commercial HVAC chillers and industrial process cooling, this chiller reciprocating compressor features advanced capacity regulation and thermal management systems for optimal performance in demanding applications.
- Flexible Energy Regulation & Load Adaptation: Solenoid-controlled 2-stage capacity regulation system (100% and 50% steps) matches refrigerant displacement to thermal loads, avoiding frequent motor restarts and optimizing power consumption.
- Suction Gas-Cooled Motor Architecture: Internal gas-flow channels dissipate heat before compression, maintaining lower operating temperatures during continuous low-evaporating-temperature duty cycles.
- Heavy-Duty 4-Cylinder Mechanical Assembly: Rugged 4-cylinder platform with dynamically balanced crankshaft, wear-resistant bearings, and precision piston-connecting rod linkages for smooth operation.
- Integrated Suction Filtering & Safety Protections: Outer-accessible high-density suction filter screen and internal pressure relief valve with INT6902 electronic protection module.
Applications
- Commercial HVAC & Liquid Chillers: Central commercial air conditioning plants, modular fluid chillers, and HVAC liquid cooling skids
- Low-Temperature Cold Storage: Walk-in freezers, cold chain distribution logistics, and commercial frozen food storage facilities
- Industrial Process Chilling: Industrial cooling loops requiring continuous operation, precise temperature maintenance, and low vibration output
- Parallel Multi-Compressor Rack Systems: Supermarket parallel compressor racks subject to daily load swings

Frequently Asked Questions
Q1: What physical installation space should be reserved for servicing the outer suction filter?
A1: Technicians should ensure adequate lateral clearance on the suction side valve end to allow removal and cleaning of the outer-accessible suction filter screen during routine maintenance overhauls.
Q2: What is the benefit of the Part-Winding (PW) starting option on the SP4LF1200 motor?
A2: Part-Winding starting reduces peak electrical inrush current during startup (75 A PW vs 125 A DOL), minimizing voltage fluctuations on electrical supply lines in commercial buildings.
Q3: What oil type is pre-filled in the compressor and what is the standard recharge capacity?
A3: The compressor comes pre-charged with 2.6 dm³ of factory-approved lubricant suitable for common refrigerants, which should be verified via the sight glass after system oil equalization.
Q4: What is the typical production and delivery timeline for volume OEM orders?
A4: Standard factory batch orders are completed within 10 to 15 working days, while stock sample units can be prepared for dispatch within 3 business days.
Q5: What international commercial trade terms are supported by Coolstart?
A5: We support FOB Shenzhen and EXW trade terms, with USD settlements handled via T/T or Western Union transfers.
