Honeywell announce New Low GWP refrigerant

Honeywell has announced the availability of Solstice® L40X (R455A), a refrigerant suitable for medium- and low-temperature standalone applications such as hermetically sealed systems in refrigerated plug-in type-cabinets. Solstice® L40X provides up to 3 percent higher capacity and up to 6 percent better efficiency at low temperature than the current, widely used refrigerant R-404A.

By 2022, the European Union’s F-Gas regulations will ban the use of refrigerants with global-warming-potential (GWP) greater than 150 in new hermetic commercial applications such as plug-in and refrigeration condensing units. Solstice® L40X has a GWP of 148, which is more than 96 percent lower than R-404A. Solstice® L40X also has a lower risk of flammability compared to other refrigerant options such as propane, whose usage in such applications is limited to small amounts and can incur extra costs.

Solstice® L40X (R-455A) is a blend of R-1234yf, R-32 and R-744 and is rated A2L by ASHRAE. Leading hermetic compressor manufacturers have validated the performance of Solstice® L40X in tests over the last 18 months and have found similar capacity and discharge temperatures, but with improved efficiency, when compared to R404A. Solstice® L40X can be used across many segments of the HVACR industry, including small charge, plug-in type cabinets, condensing units and monoblocks for cold rooms and freezer rooms, small chillers, heat pumps, and chillers. The product complements other Low GWP products in the Solstice® range such as  Solstice®N13, Solstice®N40.
