Solstice® 454B (R-454B)

Solstice® 454B (R-454B) is a non-ozone depleting, zeotropic blend designed as a low GWP alternative to R-410A in comfort air cooling and reversible heating applications.

Solstice® 454B (R-454B) is a non-ozone depleting, zeotropic blend designed as a low GWP alternative to R-410A in comfort air cooling and reversible heating applications.Solstice 454B demonstrates improved efficiency and is a capacity match to R-410A, minimizing the redesign costs and capital expenditures. It 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
