CRYSTAL-DR22S3
The product description
CRYSTAL-DR22S3 is a refrigerant oil developed for the use of HFC refrigerant R134a refrigerator 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 can provide long life lubrication protection for refrigerator compressors.
CRYSTAL-DR22S3 is suitable for refrigerator compressors using chlorine-free refrigerant (R134a, R600a, etc.).
Excellent features of CRYSTAL-DR22S3 include:
- - Polyol ester (POE) synthetic base oil, high temperature resistance, excellent lubrication performance
- - Base oils work in concert with high performance additives to provide long life lubrication protection
- - Has good compatibility with refrigerant R134a and will not be deposited in heat exchange pipes
- - Good high temperature chemical stability and hydrolysis stability
- - Good low temperature mobility
