R452B (Opteon™️ XL55, Solstice® L41y) is a replacement designed to serve as a low GWP alternative to R410A in positive displacement, comfort air cooling and reversible heating applications.

With similar efficiency and matching capacity to R410A, it can help to further minimize the redesign costs and capital expenditures. The design compatibility of R452B enables OEMs to transition their R410A equipment to a lower GWP alternative faster.

R452B discharge temperature is much lower than R32 and very close to the R410A, indicating that discharge temperature mitigation may not be required. R452B is A2L mildly flammable so is only for use in new equipment.
