DESCRIPTION

R452A was developed by Honeywell and Chemours as a lower GWP R404A replacement in transport refrigeration with some use in DX low to medium temperature refrigeration, you may also see it referred to by their respective manufacturer trade names - Solstice® 452 and OpteonTM XP44.

Truck R404ADue to the high Global Warming Potential of R404A (GWP 3,922) we can no longer continue to use R404A.

R452A is a 3-part blend consisting of R32, R125 & R1234yf and has been classified by Ashrae as A1 non-flammable.

R452A has a GWP of 1,945 it is less than half the GWP of R404A so is a much more environmentally friendly option.

When looking at GWP values long term sustainable low GWP replacements need to have a GWP no higher than around 300 and ideally below 150.

Although the GWP of R452A is only half of R404A it is still regarded as low to medium and so is not considered a long-term replacement.

Trailer refrigeration and condensing units have been successfully launched with R-452A and has been endorsed by several compressor manufacturers, whose tests have demonstrated similar capacity, efficiency and discharge temperature to R-404A.

As R452A has been classified as A1 non-flammable by Ashrae it can also been used to retrofit existing systems.
