Buy Quality R422A Refrigerant Gas

R422A Refrigerant Gas,R422A is a HFC refrigerant blend of R125, R134a and R600a. It was typically used to replace R22, R502 and blends such as R402A, R403B, and R408A in medium and low temperature refrigeration systems.

The refrigerant for the food industry

R-422A, also known as Freon™ (Isceon) 79, is an easy-to-use, non-ozone depleting HFC refrigerant originally designed to replace R-22, the R-502 and refrigerant mixtures containing HCFCs.

R-422A is a more practical conversion option than R-404A or R-507, not requiring the total replacement of mineral oil with polyester.



R-422A is used in direct expansion, low and medium temperature commercial and industrial refrigeration including: food service, supermarkets, food storage and processing, ice machines.



  • It enables quick, easy and profitable conversions
  • It allows the continued use of existing systems
  • Much lower delivery temperature than R-22
  • It can be recharged during maintenance, without having to remove the entire refrigerant charge
  •  Possible Extension of the life of the compressor


Recommended lubricants:

R-422A is compatible with new and traditional lubricants (mineral oil, alkylbenzene or polyester). Most of the time, it is not necessary to change the type of lubricant during the conversion. In some systems, with complex piping configurations, it may be necessary to add Poe oil.

How R-448A compare to R-404A?

R-448A has a similar cooling capacity with improved energy efficiency compared to R‑404A. In many cases the compressor discharge temperature will not be a concern but for some low temperature applications, under the same operating conditions,R‑448A will exhibit a significantly higher compressor discharge temperature than R‑404A which, in a retrofit situation, may need to be managed.Full theoretical performance comparisons at customer specified conditions are available from Lunxabrefrigeration on request.

Packaging and Supply
