What type of coolant should I use with the Coolmate 3.5 water cooler?
Miller Low-Conductivity TIG Coolant (Stock No. 043810) is recommended, which contains a base of ethylene glycol and deionized water. It protects against freezing to -38°C and boiling to 108°C, and must be ordered in quantities of four one-gallon recyclable plastic bottles. (Page 6)
