CRYSTAL-DR32S4
The product description
CRYSTAL-DR32S4 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-DR32S4 is suitable for refrigeration compressors using HFC refrigerant (R410a, R134a, etc.), especially for scroll compressors with R410a refrigerant.
Excellent features of the CRYSTAL-DR32S4 include:
- - resistance to high temperature
- - Superior lubrication and wear prevention
- - Has good compatibility with refrigerant R410a and will not be deposited in the heat exchanger pipe
- - Good hydrolysis resistance
- - Good low temperature mobility
