  • Product Description
  • | Product Overview                   
    SynCold® RL series products are high‑performance, fully synthetic refrigeration lubricants specifically developed for lubricating refrigeration compressors. Formulated with proprietary polyol ester (POE) technology and a unique additive system, these lubricants deliver exceptional lubricity, wear resistance, chemical and thermal stability, as well as hydrolytic stability. SynCold® RL is miscible with HFC, HCFC, and HFO refrigerants and is recommended for HVAC, commercial, and industrial refrigeration applications.

    SynCold® RL series products can also be custom-designed by optimizing the molecular structure of synthetic POE to meet the specific performance requirements of equipment manufacturers, offering tailored solutions developed in-house.

     

      | Applications and Compressor Types

    • HFCs, HCFCs, HFOs
    • Reciprocating, screw, rotary, centrifugal, and scroll compressors

     

     

     

    | Technical Features and Performance Advantages

    Features Advantage
    Excellent high-temperature stability Improve evaporator cleanliness, reduce unscheduled downtime, and lower maintenance costs.
    Clear miscibility and the P–V–T relationship with HFCs Ensure the refrigeration system operates at high efficiency and achieves proper oil return.
    Excellent wear resistance Reduce compressor wear and lower maintenance costs.
