R438A is a HFC refrigerant that can be used in R22 replacement over a wide range of applications. It has been designed to closely match the pressure, temperature, enthalpy, and mass flow properties of R22, for a seamless R-22 replacement.
Key Features:
R438A matches R22 in terms of capacity and efficiency in most systems
Significantly lower discharge temperature then R22 which may prolong life of the compressor
Compatible with traditional and new lubricants although POE is recommended, providing quick, cost-effective R22 replacements*
Another alternative to R22 is R422D, a non-ozone depleting HFC refrigerant (Ashrae A1), suitable for low and medium temperature refrigerations systems.
Key Features:
R422D is a HFC blend refrigerant which has a lower discharge temperature than R22, so may extend the life of the compressor
Matches R22 in terms of capacity and efficiency in most systems
Compatible with traditional and new lubricants although POE is recommended, providing quick, cost-effective R22 replacements*
* Refer to compressor manufacturer's guidelines for lubricant recommendations
