The refrigerant R407A gas is commonly used in low- and medium-temperature refrigeration applications. It was previously used as a replacement for R22, for example.
R407A is an excellent, energy-efficient low-GWP gas suitable for many R404A systems. Energy savings of up to 10% have been reported in many systems. R407A also boasts a lower discharge temperature than other R404A replacements.
Both R407A and R407F are well-known replacements for R404A.
R407A gas applications and use
Refrigeration systems used in commercial, industrial and transport applications. R407A is a replacement for R404A and, after an oil change, can also serve as a replacement gas in some R22 systems.
Alternative refrigerants to R407A gas
R407A gas can be replaced with R449A, for example. It is suitable for low- and medium-temperature direct-expansion applications, new installations and, as a replacement gas, existing systems. R407A has long been known in industry, where it has been used to replace many existing R404A systems. It is compatible with the same oils, elastomers and plastics as R404A. Nevertheless, R407A cannot serve as a direct replacement for R404A, as the differences in compressor discharge temperature and the temperature increase caused by R407A must be taken into account.
