Product Overview
R422D is a non-ozone-depleting HFC refrigerant blend, developed as a drop-in replacement for R22 and R502 in low and medium-temperature refrigeration systems. It is a colorless gas with a faint ethereal odor. R422D is specifically formulated to simplify retrofit applications by offering compatibility with both mineral and synthetic oils.
R422D is valued for its ease of use and reliable performance in existing equipment, particularly in supermarket refrigeration, cold storage, and transport refrigeration where R22 or R502 were previously used.
⚠️ Important Note: R422D has a GWP (Global Warming Potential) of 2230 (IPCC AR4) and is subject to phasedown regulations under the Kigali Amendment to the Montreal Protocol. Please check local regulations before purchase, especially in regions with active F-gas reduction policies. R422D is not recommended for new equipment design, but remains a practical retrofit solution for existing R22 systems.
