Overview
The R422B Refrigerant Cylinder is a dependable retrofit refrigerant developed to replace R22 in existing air conditioning and refrigeration systems. Designed to help HVAC professionals transition away from ozone-depleting HCFC refrigerants, R422B provides reliable cooling performance while allowing continued operation of legacy equipment.
R422B offers an efficient and practical solution for extending the life of R22 systems without the high cost of complete equipment replacement.
What Is R422B?
R422B is an HFC refrigerant blend formulated as a retrofit alternative to R22 (HCFC-22). It consists primarily of R-125, R-134a, and R-600a, engineered to deliver operating pressures and performance characteristics similar to R22 in retrofitted systems.
Key classifications include:
-
ASHRAE Safety Class: A1 (non-flammable, low toxicity)
-
Refrigerant Type: HFC retrofit blend
-
Ozone Depletion Potential: 0 (ozone-friendly alternative)
R422B enables HVAC technicians to service older systems while complying with environmental regulations phasing out R22.
Designed for R22 System Retrofits
R-422B is commonly selected for retrofit projects because it:
-
Provides similar operating characteristics to R22
-
Requires minimal equipment modification in many systems
-
Supports continued operation of legacy HVAC equipment
-
Eliminates ozone-depleting refrigerant usage
In many applications, existing mineral oil or alkylbenzene lubricants remain compatible, simplifying the retrofit process.
Applications
R-422B is suitable for retrofitted systems such as:
-
Residential air conditioning systems
-
Commercial HVAC units
-
Split systems and rooftop units
-
Medium-temperature refrigeration systems
-
Refrigerated storage and display equipment
-
Process cooling applications
Environmental Benefits
As global regulations phase out HCFC refrigerants, R422B provides a compliant alternative:
-
Zero Ozone Depletion Potential (ODP = 0)
-
Supports transition away from R22 refrigerant
-
Helps maintain older equipment responsibly
While R422B still carries Global Warming Potential (GWP), it serves as an effective transitional refrigerant for existing installations.
