Low GWP Alternatives



R452B (otherwise known as Opteon™ XL55 by Chemours, or Solstice® L41y from Honeywell) is a mildly flammable refrigerant with a GWP of less than 700. It is used as replacement of R410A in new equipment designs in positive displacement comfort air cooling and reversible heating applications.

R452B offers similar efficiency and capacity to R410A and has a much lower discharge temperature than R32. Classified as mildly flammable, R452B may be a great alternative due to its reduced discharge temperature, design capability and improved performance.
