What should you know about in Chillers?

The Chiller R-1234yf is a replacement alternative for current chillers that work with R134a.

  • The miscibility of HFO-1234yf with POE oils is comparable to that of HFC-134a over the target operating range.
  • HFO-1234yf is not miscible with mineral oil or alkylbenzene lubricants.
  • The interactions of HFO-1234yf with common classes of lubricants are, in general, similar to HFC-134a.
  • Thermal stability and compatibility with chiller construction materials.
  • The stability of HFO-1234yf was examined in the presence of materials that I probably find in practical use according to the sealed tube test methodology
