Chemours announce New Low GWP refrigerants

Chemours has announced the availability of its new range of low GWP HFO-based “mildly flammable” refrigerants.

The new Opteon™ XL  Series currently comprises five refrigerants; Opteon™ XL10 (R-1234yf), which can replace R-134a, Opteon™XL20 (R454C) and Opteon™XL40 (R-454A) both potential alternatives  to replace R-404A and R-507. Whilst Opteon™XL41 (R-454B) and Opteon™XL55 (R-452B) are two new blends to replace R410A. All are classified  by Ashrae as  A2L “mildly flammable” refrigerants.

The Opteon™ XL Series will provide the refrigeration and air conditioning industry with very low GWP refrigerants that help further decrease CO2-equivalents to their lowest level in new equipment designs. Classified as mildly flammable (ASHRAE/ISO Class 2L), these XL products allow much higher charge sizes than other more flammable refrigerants and can be safely used when following the applicable codes and standards.

Based on hydrofluoro-olefin (HFO) technology, they offer similar properties, and in many cases increased performance, compared to the current hydrofluorocarbons (HFCs) they are designed to replace.

This combination of performance, safety and sustainability allows for the XL Series to offer the optimal balance of properties to help ensure that new equipment designs function at their highest levels, specifically designed for their use and not for retrofit applications.

All of the refrigerants in the  Opteon™ XL series are currently being tested by leading equipment manufacturers. Codes and standards such as EN378 are also being modified to include class 2L mildly flammable refrigerants. These codes and standards will enable lower GWP 2L refrigerants to be used safely across a wide range of applications.

The Opteon™ XL Series complements the Opteon™ XP Series of non-flammable low GWP refrigerant already launched which include Opteon™ XP40 (R-449A),  Opteon™ XP44 (R-452A) and Opteon™ XP10(R-513A) See our product pages for further information on all these refrigerants.
