As a first trial, Lowe Rental Ltd. used Opteon XL20 in a chilled drinks cabinet designed for R-404A to see if was a suitable replacement. The charge size was approximately 350 g. Picture: Lowe Rental Ltd.
​Chemicals manufacturer, Chemours, is adding to its range of low global warming potential refrigerants in its Opteon XL portfolio.
​The range is specific to the air conditioning and refrigeration industry. The A2L (mildly flammable) refrigerants allow for higher charge sizes than other refrigerants with a higher flammability. The refrigerants are based on hydrofluoro-olefin (HFO) technology, and have similar properties, and higher performance, in most cases, than the hydrofluorocarbons (HFCs)  they replace.

There are five refrigerants in the Opteon XL range, namely Opteon XL10 (a R134a replacement), Opteon XL20 and XL40 (which replace R22 and R404A/507), and Opteon XL41 & XL55 (replacing R410A).
Opteon XL10 (R-1234yf) replaces R134a and has a GWP of less than 1. Chemours states it is a replacement for 'new equipment designs'. Engineers should use them in positive displacement, direct expansion medium temperature commercial and industrial applications.
Opteon XL20 (R-454C) replaces R404A and R407C refrigerants in new equipment designs. It has a GWP of 146. Chemours designed it for positive displacement, direct expansion low- and medium temperature commercial and industrial applications. Because it comes under the 150 threshold value in F-Gas legislation 517/2014 and Eco-design, the refrigerant is ideal for hermetically-sealed systems.

Opteon XL40 (R-454A) in an R404A replacement and has a GWP of 238. Engineers should use the refrigerant in positive displacement, direct expansion low- and medium temperature commercial and industrial applications.

Opteon XL41 (R-454B) has a GWP of 467 and replaces R410A in new systems. Its applications include positive displacement, direct expansion air conditioning, heat pump and chiller applications.

Finally, Opteon XL55 (R-452B) has a GWP of 676, and it replaces R410A, but has 'design compatibility with R410A equipment and lower 2L flammability properties'. The refrigerant can be used in positive displacement, direct expansion air conditioning, heat pump and chiller applications.
