Opteon™ XP40 (R-449A)
Refrigerant

The Market Leading Solution for Retail Refrigeration
Opteon™ XP40 (R-449A) was commercially launched inOctober 2014 by Chemours (formerly DuPont) and quickly
became the market leading low GWP R-404A replacement. Since the product launched many supermarket
chains in the United States, Canada, Germany, Spain, Italy,Belgium, Austria, UK, France, Greece and the Netherlands
have installed Opteon™ XP40 in both low temperature andmedium temperature applications. The results from trials
were consistently positive with energy savings ranging
from 2-3% in low temperature applications and 8-11% in
the medium temperature applications when compared toR-404A.
You may be asking, how does Opteon™ XP40 compare withR-448A?

The composition differences between Opteon™ XP40 andR-448A is minor with R-448A containing an additional
component, R-1234ZE.
As can be seen in Tables 2 and 3, the cooling capacity andenergy efficiency of both products are very similar, but
Table 3 shows Opteon™ XP40 has a more favorable
compressor discharge temperature, smaller temperature
glide, slightly lower condensing pressure, and a slightly
improved pressure ratio compared to R-448A.
Taking into account the excellent performance, large
amount of practical experience, the widespread availability,
and the improved properties, it’s no wonder Opteon™ XP40
has become the leading nonflammable low GWP
alternative for retailers across the globe.
