The new Opteon XL Refrigerant Charge Calculator free online app from Chemours is designed to work out charge sizes, according to EN378 guidance, to help with the calculations process.
It works by allowing you to select the location, access categories and preferred Opteon XL refrigerant followed by entering the room dimensions and estimated refrigerant charge.
You will then be displayed with the charge calculation which can be viewed and exported to a pdf.
It can be found and used on the Opteon website here.
