In order to have good protection against frost we recommend using a coolant with the following characteristics :
ready to use:already mixed with the correct concentration of glycol depending on the geographic area of the installation
Effect anti corrosion
glycol with the lowest possible viscosity in negative temperatures
Here are the glycol references already validated with the aluminum exchanger of the SPRING4 panel:
