R-434A is an almost azeotropic mixture of HFC and HC refrigerant gases, with zero depletion of the ozone layer, used as a direct substitute (drop-in) for R-22 in equipment with an adjustable expansion system (TXV) positive, medium and low evaporation temperatures down to -35ºC.

It is the recommended solution to replace R-22 in large air conditioning equipment and refrigeration systems in general. Easy, direct and effective. Compatible with the original system oil. Same cooling capacity as R-22, even at low temperatures. Ideal for flooded systems thanks to its low temperature glide. May require opening / regulating expansion valve.


· Quick, simple, economical and efficient replacement.

· Does not damage the ozone layer, ODP = 0.

· Compatible with the original system oil.

· Allow to maintain existing equipment.

· Equipment can be refilled in case of leakage.

· Although the standard recommendation is not to mix refrigerants, studies carried out show that it can technically be mixed with R-22 in any proportion.

· Discharge temperatures much lower than R-22, which prolongs the life of the compressor.

· They reach the same cooling capacity and energy efficiency as R-22.
