Opteon™ XL55 (R-452B) Refrigerant

A High-Performance Refrigerant Ideal to Replace R-410A for AC and Chillers

Many air conditioning and chiller systems use refrigerants that need to be replaced due to phase down/phase out schedules set by regulatory mandates. Opteon™ XL55 (R-452B) refrigerant replaces R-410A—and offers all the same functionality.

Opteon™ XL55 (R-452B) is a non-ozone depleting (ODP), low global warming potential (GWP), hydrofluoroolefin (HFO) based refrigerant. It easily adapts to R-410A designs while offering the same optimal balance of performance, thermal characteristics, and ultra-low flammability.

A wide range of residential, light commercial, and commercial-positive displacement, direct-expansion (DX) AC, heat pumps, and chillers can use this refrigerant, including:

  • Window units
  • Portables
  • Ducted, mini-, and multi-splits
  • DX chillers
  • Packaged Terminal Air Conditioners (PTACs)

Features and Benefits

Opteon™ XL55 offers a combination of design compatibility and reduced compressor discharge temperature when compared to other R-410A alternatives like R-32. This enables an easy transition of R-410A to Opteon™ XL55 with minimal re-design and capital expenditures.

Classified as mildly flammable (A2L), Opteon™ XL55 allows much higher charge sizes than other flammable refrigerants and can be safely used by following the applicable codes and standards. Additional benefits of Opteon™ XL55 include:

  • Improved energy performance compared to R-410A (up to 5% energy efficiency improvement)
  • A very low temperature glide, with easy top-off after leak repair
  • A low GWP of 676 (a reduction of >66% vs. R-410A¹)
