R-422D is a refrigerant blend consisting of R125, R134a, and R600a. It is commonly regarded as a suitable ‘drop-in’ substitute for R22 in various refrigeration and air conditioning systems. R-422D is versatile and can be employed in a wide range of temperature applications, including low, medium, and high temperatures.

R-422D preserves the longevity of systems by utilizing the existing equipment designed for R-22, eliminating the need for a full system replacement or upgrade in cases of R-22 leaks. It delivers comparable capacity and efficiency to that of R-22. Moreover, it maintains a lower discharge temperature compared to R-22, potentially extending the lifespan of the compressor.
