R32
R-32
Low GWP (675) A2L safety class alternative to R-410A for use in air conditioning and heat pump applications.
Features and Benefits
- Low GWP –Sustainable and compliant with F-Gas legislation
- Increased performance compared to R-410A – Lower indirect emissions and operating costs.
- Single component refrigerant – can be used in direct expansion and flooded systems. No temperature glide.
- Approved by many equipment manufacturers – Large choice of new equipment available.
Packaging and Supply
- Climalife supply R-32 in 9kg or 46kg returnable cylinders and 702kg returnable drums.
- Conforms to AHRI 700-2016 specifications.
- As R-32 is safety class A2L, it is important to use the right equipment for handling R-32.
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-32 compare to R-410A?
R-32 has a better cooling and energy efficiency performance compared to R-410A. R‑32 does have the safety classification A2L due to its low flammability. R-32 should only be used in systems compatible for use with low flammability refrigerants.
Full theoretical performance comparisons at customer specified conditions are available from Climalife on request.
