Refrigerant R-455A

R-455A is an ultra-low GWP HFC/HFO refrigerant blend with a global warming potential below 150. It is not affected by the restrictions established under the current F-Gas Regulation (EU 2024/573) and is exempt from the Spanish fluorinated greenhouse gas tax. It is an advanced solution for commercial and industrial refrigeration applications.
It provides cooling capacity comparable to R-404A while delivering higher energy efficiency. Its A2L safety classification and high practical charge limit make it one of the most attractive refrigerants for next-generation commercial refrigeration systems.
