HFC-R422D Refrigerant (High-Capacity R22 Replacement Solution)
HFC-R422D is a non-ozone depleting HFC blend specifically formulated as a high-capacity retrofit solution for R22 in commercial refrigeration systems. With zero ODP (Ozone Depletion Potential) and a GWP of 2,729, it provides an environmentally responsible alternative while delivering 5-10% higher cooling capacity compared to R22 in most medium-temperature applications.
Key Technical Advantages:
Enhanced cooling capacity reduces compressor runtime and energy consumption
Near-azeotropic behavior (<3°C glide) ensures stable system operation
Direct drop-in compatibility with most R22 systems using POE oil
Non-flammable formulation (ASHRAE A1 safety classification)
Wide operating range (-30°C to +10°C evaporating temperature)
