Honeywell Solstice® R454B demonstrates improved efficiency and matching capacity to R-410A, with a GWP that’s 78% lower, minimizing redesign costs and capital expenditures. Solstice 454B (R-454B) is the most optimized R-410A replacement, providing easy conversion with minimal changes from a R-410A design. Thanks to its high critical temperature and broader operating envelope in low evaporating temperatures, Solstice® 454B outperforms other refrigerant alternatives in normal and high ambient conditions in a variety of applications such as:

Direct expansion (DX) chillers
High-pressure heat pumps
Residential/light commercial A/C
Commercial packaged systems
