WARNING
Due to the presence of glycol, the system can corrode. Uninhibited glycol becomes
acidic under the influence of oxygen. High temperatures and the presence of copper
accelerate this process. The acidic uninhibited glycol attacks metal surfaces and
forms galvanic corrosion cells that cause severe damage to the system. It is therefore
important to respect the following:
▪
A qualified water specialist has treated the water.
▪
Select glycol with corrosion inhibitors to prevent glycol oxidation and subsequent
acid formation.
▪
Do NOT use automotive glycol because these contain corrosion inhibitors with
only a limited lifetime. On top of that, they also contain silicates that can foul or
plug the system.
▪
Do NOT use galvanised pipes in glycol systems because they provoke certain
components in the glycol's corrosion inhibitor to precipitate.
