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.

- 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.
