CRYSTAL-DR75S2
The product description
CRYSTAL-DR75S2 is a refrigerant oil developed for the use of environmentally friendly refrigerant R410a compressor, especially optimized for T3 air conditioning compressor. The product is made of high temperature resistant polyol ester (POE) base oil independently produced by the company, combined with high performance antiwear agent, which has excellent refrigerant phase solubility, high temperature lubricity, high temperature stability and low temperature fluidity, so as to provide long life lubrication protection for refrigeration compressor.
CRYSTAL-DR75S2 is suitable for refrigeration compressor using HFC refrigerant (R410a, R32, R134a, etc.), especially for T3 condition air conditioning compressor.
Excellent features of the CRYSTAL-DR75S2 include:
- - Suitable for T3 harsh working conditions, still provide good protection for the compressor under high temperature and pressure
- - The base oil works in concert with the antiwear agent to further improve the wear resistance
- - Has good compatibility with refrigerant R410a and will not be deposited in the heat exchanger pipe
- - Good high temperature chemical stability and hydrolysis stability
- - Good low temperature mobility
