| Honeywell Genetron® Performax™ LT (a ternary blend of HFC-32/HFC-125/HFC-134a), serves as a non-ozone depleting replacement for HCFC-22 in various commercial refrigeration applications, particularly in low-temperature applications. Since Genetron Performax LT (R-407F) is a close match to HCFC-22, it also serves as a retrofit fluid in applications where HCFC-22 is used. Applications: Genetron Performax LT is well-suited as a replacement for HCFC-22 in low- and mediumtemperature commercial refrigeration applications such as supermarket freezer cases, display cases, reach-in coolers, transport refrigeration, and ice machines. Genetron Performax LT is not a “drop-in” replacement. Lubricants such as mineral oil and alkylbenzene that have traditionally been used with R-22 are immiscible with Genetron Performax LT. Miscible synthetic lubricants such as polyol esters should be used to ensure adequate oil return. Genetron Performax LT is a blend refrigerant. It is essential that systems be charged with liquid from the cylinder. Vapor charging Genetron Performax LT may result in the wrong refrigerant composition and could damage the system. A throttling valve should be used to control the flow of refrigerant to the suction side to ensure that a liquid slug does not enter the compressor. For more details about proper retrofitting procedures, see “Servicing Considerations” and “Retrofitting Existing Systems” in this brochure.
