Opteon™ XL41(R-454B) is a mildly flammable, low global warming potential (GWP) based hydrofluoroolefin (HFO) refrigerant designed to replace R-410A in new systems.

Provides an optimal balance of properties for R-410A replacement in direct expansion volumetric air conditioning systems, heat pumps and chillers.

It is the replacement refrigerant of the Opteon™ family for R-410A, which has the lowest GWP (78% less) and ensures better performance.

It offers similar properties to R-410A, making it easy and cost-effective to apply to new plants without requiring significant modifications.

Opteon™ XL41 is classified as a mildly flammable refrigerant (ISO/ASHRAE class 2L ).

It is recommended to consult national regulations and standards such as PED, EN 378 or ISO 5149 in order to verify the permissible load, the characteristics of the systems and the requirements for safe handling in relation to the application for which it is intended.


  • Direct expansion volumetric air conditioning systems, heat pumps and chillers
  • Residential, light commercial, commercial sector
  • Direct replacement in all types of plants based on R-410A:
    • portable devices
    • mini-split
