R-453A (RS-70)

R-453A (RS-70) is a non-azeotropic HFC and HC refrigerant gas mixture, with zero ozone depletion and low global warming potential, used as a direct substitute (drop-in) for R-22 in equipment with a fixed (capillary) or adjustable (TXV) expansion system and working with positive, medium or low evaporation temperatures.

It is the direct HFC substitute for R-22 with the lowest GWP on the market, and therefore the refrigerant that least affects the greenhouse effect of the refrigerants in its class. It is the recommended solution to replace R-22 in all types of installations except flooded evaporators, where the only solution is RS-45 (R-434A). Easy, direct and effective. Compatible with the original system oil. Studies conducted by the Polytechnic University of Catalonia have shown that RS-70 is the refrigerant that provides more cooling capacity and coefficient of performance compared to R-422D, R-417A, R-438A, R-424A and R-434A.

NOTES:

– Fast, simple, economical and efficient replacement.

– No harm to the ozone layer, ODP = 0.

– Compatible with the original system oil.

– They allow the maintenance of existing equipment.

– Equipment can be refilled in case of leakage.

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

– Lower discharge temperatures than R-22, which extends the life of the compressor.

– It achieves practically the same cooling capacity and energy efficiency as R-22.

– Global Warming Potential (GWP): 1765.

– Boiling point at 1,013 bar (ºC): -42,2

– Temperature glide or glide (ºC): 4.2

– Saturated vapor density at 25ºC (kg/m3): 41.7

– UN NO.: 1078

– Safety classification: A1. Low toxicity and non-flammable.

– Always load in liquid phase.
