NOTICE
Corrosion as a result of unsuitable materials used to connect the cooler
Corrosion damage can occur if you use unsuitable materials to connect to the cooler.
• We recommend that you use brass or stainless steel fittings when connecting the cooler.
Calculating the thermal power that can be dissipated by the cooler
Average density of the coolant:
