Solstice® 454B (R-454B) Refrigerant – A lower GWP replacement for R-410A
Honeywell continues to innovate and bring new solutions to the market to meet industry needs and our customer preferences. Solstice® 454B (R-454B) refrigerant is a low Global Warming Potential (GWP) HFO blend designed to replace R-410A in stationary air conditioning/heating applications and scroll chillers.
R-410A replacement - What you need to know?
R-410A is one of the most widely used refrigerants around the world for residential and light commercial cooling and heating applications. Furthermore, the final rule on the Technology Transition Program under the AIM act, signed on Oct 5, 2023, restricts the use of higher-GWP HFCs (like R-410A) in various sub-sectors, including new refrigeration, air conditioning, and heat pump (RACHP) products and equipment. To comply with regulatory phasedowns of high-GWP products, R-410A must be replaced with a safe, energy-efficient, lower-GWP solution with similar or better performance in the new equipment.
