Honeywell Solstice® R-454B is a next-generation, low-GWP refrigerant engineered as an optimized replacement for R-410A. It delivers comparable cooling capacity and improved energy efficiency while reducing global warming potential (GWP) by approximately 78%.
Designed for a smooth transition from R-410A, R-454B minimizes redesign costs and limits the need for major equipment modifications. This makes it an ideal solution for manufacturers and HVAC professionals seeking compliance with evolving environmental regulations without sacrificing performance.
With a high critical temperature and a wide operating envelope, Solstice® R-454B performs exceptionally well across a broad range of conditions, including normal and high ambient environments. Its strong performance at low evaporating temperatures ensures reliable operation in demanding HVAC applications.
