Refrigerant R-507 is a non-ozone-depleting, azeotropic blend of HFC refrigerants R-125 and R-143a. It is engineered to closely replicate the performance characteristics of R-502, making it a trusted solution for demanding refrigeration environments.
Due to its stable composition and excellent low-temperature performance, R-507 is widely used in commercial and industrial refrigeration systems where consistent cooling and efficiency are critical.
