El R-422D is a mixture of non-azeotropic HFC and HC refrigerant gases, with zero ozone layer depletion, used as a direct drop-in replacement for R-22 in equipment fitted with an adjustable expansion system (TXV) at above-zero temperatures and mid-range ones up to -15ºC.  

It was originally designed to replace R-22 in direct expansion water coolers. It can also be used in domestic and residential air conditioning systems, as well as mid-range temperature cooling systems. Compatible with the system’s original oil. Cooling capacity slightly lower than that of R-22. Opening/adjusting of the expansion valve may be required.


· Water coolers.

· Rooftop.

· Multi-splits / Cassette.

· Cooling chambers.


  • High temperatures
  • Medium temperatures
  • Drop-in replacement


· Quick, easy and inexpensive replacement.

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

· Compatible with the system’s original oil.

· No need for existing equipment to be changed.

· Equipment can be refilled in the case of leakage.

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

· Slightly lower cooling capacity and energy efficiency than R-22.

· Temperature slip or glide (ºC): 4.5

· Saturated vapour density at 25ºC (kg/m3): 53.1

· UN nº: 1078

· Safety classification: A1. Low toxicity and nonflammable.

· Always load in its liquid phase.
