R438A, also marketed under trade names like MO99, is a non-ozone-depleting HFC refrigerant blend formulated to serve as a direct retrofit for R22 in existing air conditioning and refrigeration systems. It contains a blend of R-32, R-125, R-134a, R-600, and R-601a, offering similar cooling capacity and operating pressures to R22 while eliminating the need for major component changes during conversion.
Designed to simplify the transition away from R22, R438A is compatible with existing mineral oil, alkylbenzene, and POE lubricants, often allowing retrofits without a complete oil flush. This refrigerant supports both medium- and low-temperature applications and is suitable for use in residential, commercial, and light industrial systems.
With zero ozone depletion potential (ODP) and a lower Global Warming Potential (GWP) than many traditional HCFC refrigerants, R438A offers an environmentally responsible option for extending the service life of legacy R22 equipment. It is supplied in DOT-approved steel cylinders, ensuring compliance with safety and handling standards.
Applications:
✅Residential and Commercial HVAC: Ideal for air conditioning systems originally charged with R22.
✅Medium and Low-Temperature Refrigeration: Suitable for cold rooms, refrigerated display cases, and food storage systems.
✅Light Industrial Cooling: Used in process cooling and specialty systems requiring R22 replacement without full redesign.
