Application: Medium and low temp refrigeration applications, appliances. Retrofitting R-12 or blends used to previously retrofit R-12 systems.Performance: Similar capacity and efficiency to R-12. Higher pressures, similar to R-401A and R-409A

Lubricant: R-450A requires polyolester (POE) lubricant. Follow manufacturer’s recommendations for changing mineral oil to POE.


• Suitable low GWP retrofit replacement for R134a in DX supermarket refrigeration applications, R450A delivers a comparable carbon footprint in medium temperature applications
• Polyolester oil is recommended with R450A to ensure adequate oil return
• The same POE oil as R134a can be used with minimal adjustment to TX valves
• The small glide of R450A is of no effect in most DX systems
• Slightly reduced capacity compared to R134a
• Highly efficient when used in systems designed for R450A
