A long-term non-ozone depleting replacement for R-502 and R-22 in low- and medium-temperature commerical refrigeration systems.
R404A is made up of the components HFC-125,HFC-143a and HFC-134a.The stability of R404A can be characterized based on the stability of its refrigerant components,in this case,by the known stability of R134a.
Retrofit:
R-404A can be used to retrofit many existing R-502 systems. The physical and thermodynamic properties of the blend cause it to behave much like R-502 when used as a retrofit but it is not intended to be a direct “drop-in” for R-502 systems. Due to higher operating pressures associated with the use of R-404A as opposed to R-502, OEM product specific retrofit recommendations should be consulted for any and all pressure relief modifications and/or requirements.
