R448A Refrigerant

R448A Refrigerant

The refrigerant R448A is a zeotropic refrigerant mixture consisting of three components with different boiling temperatures. This results in a temperature glide of 6.2K at the phase change. R448A is suitable as a replacement and drop-in refrigerant for R404A inventory refrigeration systems and has a lower GWP value. R448A is particularly suitable for low and medium temperature applications. For single-stage refrigeration systems in the deep-freeze area, attention must be paid to the final compression temperature. Due to increased cylinder head temperatures, the use of a cylinder head fan may be necessary. Here, the technical specifications of the compressor manufacturers should be observed. 

The refrigerant R448A is non-flammable, non-toxic and colorless. R448A has a global warming potential ( GWP ) of more than 1 (GWP = 1387).  

R448A has an ODP (Ozone Depletion Potential ) of 0. 

R448A is  classified in safety class A1 according to ISO / ASHRAE  .

With its GWP value of more than 150, R448A is governed by the F-gas Regulation 517/2014. Thus, it is affected by the phase-down scenario provided for in the  F-Gas Regulation .
