R452A Opteon™ XP44
R-452A (Opteon™ XP44)
Lower GWP (2140) A1 safety class alternative to R-404A, R-507A for transport and low temperature hermetic compressor refrigeration applications.
Features and Benefits
- A1 (non-flammable) safety class – Ideal retrofit candidate for higher GWP refrigerants in transport and low temperature hermetic compressor refrigeration applications.
- 45% lower GWP than R-404A –More sustainable and compliant with F-Gas legislation.
- Similar compressor discharge temperatures to R-404A – Ideal for applications where compressor discharge temperatures are critical.
- Approved by many equipment manufacturers – Large choice of equipment available.
Packaging and Supply
- Climalife supply R-452A in 10kg or 53kg returnable cylinders.
- Conforms to AHRI 700-2016 specifications.
Why Choose Climalife?
Climalife are a key player in the distribution of refrigerants and other climate control products, with a nationwide distribution network and product knowledge that is second to none.
How does R-452A compare to R-404A?
R-452A has a similar performance to R‑404A and is especially suited to cases where the compressor discharge temperature is a critical operating parameter e.g. transport refrigeration and some low temperature applications using hermetic compressors.
Full theoretical performance comparisons at customer specified conditions are available from Climalife on request.
