“F-Gas Solutions”, developed by Climalife, is a simple and educational application intended for professionals to deal with European regulation (EU) 2024/573 known as “F-Gas III” which entered into force on March 11, 2024 and relating to fluorinated greenhouse gases. This application offers different tools: - A load calculator to know the GWP of the process fluids (refrigerants, hydrocarbons, gas) that you use in your equipment and obtain the load in t Eq. CO2. Two essential criteria in the F-Gas regulations, in particular for the mandatory labeling of the charge on equipment containing fluorinated greenhouse gases. - A leak detection module to inform you about the frequency of leak detection checks necessary to carry out depending on the type of process fluid used. Leak checks are in fact mandatory for all refrigeration, air conditioning, heat pump and electrical switching equipment containing fluorinated greenhouse gases. - A “Climalife Certified F-Gas Solutions” module to inform you about all the process fluids available on the market and the solutions we recommend for new and existing equipment, in accordance with F-Gas regulations.
