R-426A (RS24)Dropin

R-426A is a an almost azeotropic mixture of HFC and HC refrigerant gases, with zero ozone layer depletion, used as a direct drop-in replacement for R-12 and its HCFC substitutes such as, for example, R-409A, R-406A and DI-36 without the need to change the system’s original oil. 

R-426A has the same cooling capacity as R-12. Above-zero and average working temperatures.


· Car air conditioning.

· Domestic refrigerators.

· Cooling chambers.

· Refrigerated transport.

· Commercial refrigeration.

· Not recommended for centrifugal compressors.


  • High temperatures
  • Medium temperatures
  • Drop-in replacement


· Quick, simple and inexpensive substitution.

· 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.

· Studies undertaken show that, technically, it can be mixed in any proportion with R-12 or R134a.

· It achieves the same cooling capacity and energy efficiency as R-12.                    

· Global warming potential (GWP) = 1508

· Boiling point at 1.013 bar (ºC): -28.6

· Temperature slip or glide (ºC): 0.5

· Saturated vapour density at 25ºC (kg/m3): 30.9

· UN nº 1078                             

· Safety classification: A1. Low toxicity and nonflammable.

Refrigerant Solutions Ltd

- Less temperature slip (glide) than R437A so that the fractionation of the mixture is much lower in the event of leakage thus maintaining optimum operating conditions.

- Lower discharge pressure than R-437A which is easier on the compressor, especially in geographically warmer regions.
