Solstice® HFO Blends

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.

Overview

Solstice® 454B 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
