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.

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.
