R-434A (RS45)Dropin

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

It is the recommended solution for replacing R-22 in large climatization equipment and cooling systems in general.  Easy, direct and efficient. Compatible with the system’s original oil. The same cooling capacity as R-22, even at low temperatures. Ideal for flooded systems thanks to its low temperature slip. Opening/adjusting of the expansion valve may be required.

  • High temperatures
  • Medium temperatures
  • Low Temperatures
  • Drop-in replacement


· Quick, simple, inexpensive and effective 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.

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

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

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

· Global warming potential (GWP) = 3238

· Boiling point at 1.013 bar (ºC): -44.9

· Temperature slip or glide (ºC): 1.5

· 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.

Less temperature slip (glide) than the other direct drop-in replacements for R-22 (R-417A, R-417B, R-424A, R-422D, R438A) which means that the fractionation of the mixture in the case of leakage is much lower, thereby maintaining optimum operating conditions.

· A single replacement of R-22 for high, mid-range and low temperatures without loss of cooling capacity once the expansion valve or TXV has been adjusted.

· The only direct replacement for R-22 valid for flooded evaporators thanks to its low temperature slip (glide).
