Description
Cooling circuits that use distilled water to cool copper components such as magnets or cooling plates are susceptible to air leaks at fittings (for example, at the junction between plastic and metal tubing). The air that enters contains carbon dioxide, which lowers the pH from neutral 7 to acidic distilled water, allowing the accompanying oxygen molecules to react with the copper tubing surface, producing copper oxides. These copper oxides can accumulate and clog areas where the flow rate decreases (such as in flow reducers or collectors). This process thins the tubing walls and can eventually cause leaks. Frequent unclogging requires opening the circuit more often, which speeds up the damaging process. A very effective but costly solution is degassing each cooling circuit through reverse osmosis in a bypass setup.
