The announcement by DuPont says the refrigerants are included for use in Bitzer’s range of semi-hermetic piston and screw compressors,
R449A is DuPont’s flagship low GWP, non-flammable replacement for R404A and R507A in new and existing stationary commercial refrigeration systems. Its GWP of 1397 is significantly lower than the two refrigerants it is designed to replace but offers comparable properties and performance.
R513A is an optimised new low GWP, azeotropic, non-flammable replacement for R134a. A binary mixture of R134a (44%) and R1234yf (56%), it has a GWP of around 630. It replaces R134a in new equipment and, backed by extensive tests, has shown similar capacity and efficiency. DuPont sees XP10 having great potential as a replacement for medium temperature refrigeration applications in hybrid CO2 cascade systems. It was also recently announced as an option on Trane’s new Sintesis air-cooled chiller.
“We at DuPont are extremely pleased that Bitzer has included Opteon XP40 and XP10 in its updated compressor selection software programme,” said Kathryn K McCord, global business director, DuPont Fluorochemicals.
“This inclusion marks the final step in Bitzer’s approval of XP40 and XP10 for its compressors and sets the stage for these new low GWP refrigerants to become the products of choice in refrigeration and other applications.”
