Description
Cooling circuits running with distilled water to cool copper structures like magnets or cooling plates are vul-nerable to air leaking in. The leaked-in air contains car-bon dioxide that lowers the pH from 7 to acidic condi-tions in distilled water and enables dissolved oxygen to react with the surface of the copper tubing, forming cop-per oxides that can grow and mechanically be displaced to clog in locations where the flowrate is low. The pro-cess also reduces the wall thickness of the tubing, even-tually followed by water leakage. Regular unclogging causes the circuit to be opened more often and therefore accelerating the destructive process. A good solution to this problem comes with a steep price: degassing by re-verse osmosis in every copper cooling circuit as dis-solved oxygen is the main problem.
