Refrigerant R-507A

R-507A is a high-safety (A1), azeotropic HFC refrigerant blend. Because it is azeotropic, it exhibits no temperature glide and behaves like a pure refrigerant throughout the refrigeration cycle. It was originally developed as a retrofit replacement for R-502 and its subsequent alternatives, as well as for flooded R-22 systems. It is also used in new equipment and is suitable for applications ranging from food preservation and freezing to industrial refrigeration processes.
Due to its GWP above 2,500, its use is currently restricted in Europe.

R-507A provides stable and consistent performance thanks to its azeotropic nature, which eliminates temperature glide and ensures a constant refrigerant composition throughout operation. These characteristics have made it a preferred choice in commercial refrigeration, industrial refrigeration and low-temperature applications where operational reliability and consistent cooling performance are essential. It is particularly valued in flooded systems and freezing applications requiring high refrigeration capacity. Although it remains a technically effective solution, current environmental regulations are driving the transition toward refrigerants with lower global warming potential.
