Polyolester oil

Polyolester oil

Polyolester oil, commonly called POE oil, is a type of Synthetic oil used in refrigeration compressors that is compatible with the refrigerants R-134a, R410A and R-12. Its recommended by experts as a replacement for HFC's. Along with R134A mineral oil its recommended as a replacement for R12 mineral oil as R134A does not mix well with mineral oil. These wax free oils are sugggested for usage with chlorine free HFC systems as they provide better lubrication and stability and are more miscible with HFC refrigerants. They can meet the lubricity requirements to those of mineral oils used with CFC's and HFC's. They are compatible with most lubricants in the market. It is noted that the viscosity of the oil increases with temperature. the dispersion behavior of this oil has also been the subject of a lot of study. it is also considered by some to be a good additive to engine oil
