Chemours works with Carrier on long-term refrigerant options

USA: Chemours says it is working with Carrier Transicold in Europe to adopt one of its long-term low GWP alternatives for transport refrigeration.

Carrier Transicold Europe, located in Rueil-Malmaison, France, is planning to replace R452A in transport refrigeration in 2021. Although R452A has only been offered by Carrier as a lower GWP alternative to R404A since 2015, its GWP of 2140 means it was never going to be a viable long-term solution.

Chemours Opteon XL range of refrigerants currently includes R454C (Opteon XL20) and R454A (Opteon XL40) as potential replacements for R404A. Both are “mildly flammable A2L refrigerants.

With a GWP of 146, R454C is the lowest GWP Opteon replacement for R404A and R22 in new equipment designs. It is a blend of 78.5% of the HFO R1234yf and 21.5% R32.

R454A is also made up of the same components, but with a higher proportion of R32. This is said to give it a greater overall performance and higher cooling capacity, but with a higher GWP of 238.

Chemours says it is actively engaged with Carrier Transicold Europe in working closely with regulatory and research groups to support the use of its Opteon XL refrigerants through proper equipment design and training based on applicable codes and standards. 

Stressing the importance of transport refrigeration to the viability of the global cold chain, Chemours Fluorochemicalsvice president Diego Boeri said: “As the European F-gas regulation continues to move the HVACR industry toward more environmentally sustainable solutions, it is critical to provide lower GWP options to equipment manufacturers around the world.” 

“Carrier is committed to providing efficient, sustainable solutions for its customers,” said Bertrand Gueguen, President, International Truck Trailer, Carrier Transicold. “The selection of a low-GWP refrigerant is the next logical step in the evolution of our industry,” said Bertrand Gueguen, president, international truck trailer, Carrier Transicold.

Carrier Transicold has previously stated its commitment to CO2 as the optimum refrigerant alternative for R134a in its container refrigeration units.
