    The product description

    CRYSTAL-DR68S4 is a refrigerant oil developed for the use of environmentally friendly refrigerant R410a compressor. The product is made of high temperature resistant polyol ester (POE) base oil independently produced by the company, which has excellent solubility in refrigerant phase, high temperature lubricity, high temperature stability and low temperature fluidity, and provides long life lubrication protection for refrigeration compressors.

    CRYSTAL-DR68S4 is suitable for refrigeration compressors using HFC refrigerant (R410a, R32, R134a, etc.), especially for compressors with R410a refrigerant.

     

    Excellent features of the CRYSTAL-DR68S4 include:

    • - High temperature chemical stability
    • - Excellent lubrication and wear resistance, prolong the life of components
    • - Has good compatibility with refrigerant R410a and will not be deposited in the heat exchanger pipe
    • - Good hydrolysis property
    • - Good low temperature mobility
