Reply to "PAG Vs Ester in Compressor"

bruce381Member

good question both are used mixed together and seperately. I never have heard a good reason for either other than PAG is better for compressing certain Hydrocarbons I think since it will not mix in them.

Otherwsie both give LONG >7,000 hours operation time with little or no sludge or Coke buildup.

Esters maygive better cooling due to inherent lubricity from the ester that the pure PAG will not have so perhaps for cooler running a Ester would be better.
