Commercial Refrigeration

The F-Gas Regulation has accelerated the search for long-term refrigerant options to address the replacement of the high global warming potential (GWP) refrigerant R-404A and to reduce the environmental impact of refrigeration equipment. Always with an eye on technology, Tournus Equipment discovered the low GWP refrigerant Solstice® L40X (R-455A), which is in line with the F-Gas Regulation’s ban of refrigerants with a GWP above 150 in large centralised commercial refrigeration equipment as of 2022, while only having a low flammability.

• Over 2500 installations sold since January 2018
• R-455A has the same thermodynamic performance as R-404A in terms of discharge temperature, lower power consumption (-10%) and a coefficient of performance (COP) equivalent to R-290.
• The flammability limit of R-455A is 11 times higher than that of propane: The lower flammability limit (LFL) of R-455A is relatively high, at 11.8% (431 g/m3). It is the minimum concentration of the product that needs to be achieved in the air in order to have a potentially flammable gas mixture (and only if the other relevant conditions are also met at the same time). The upper flammability limit (UFL) is 12.9% (462 g/m3). This means that the potentially flammable concentration range (the difference between LFL and UFL) is only 1.1%.
