Solstice® L40X (R-455A)

Solstice® L40X (R-455A) a mildly flammable, zeotropic blend is designed to serve as an alternative for low, medium and high temperature applications in new systems. Its ultra-low GWP of only 146 (below 150) makes it an Fgas-ready solution. It also provides a close capacity match to R-404A, extended operating envelope when compared to propane or air- conditioning refrigerants, and high energy efficiency.

Solstice® L40X is an excellent refrigerant option for commercial refrigeration low temperature applications can be used across many segments of the HVACR industry. Like – small charge, plug-in type cabinets, condensing units and monoblocks for cold rooms and freezer rooms, small chillers, heat pumps, and chillers.
