WARNING

Possible consequence:
Electrical
shock or fire.
In case of freeze protection by glycol:
WARNING
Due to the presence of glycol, corrosion of the system is possible. Uninhibited glycol
will turn acidic under the influence of oxygen. This process is accelerated by the
presence of copper and high temperatures. The acidic uninhibited glycol attacks
metal surfaces and forms galvanic corrosion cells that cause severe damage to the
system. Therefore it is important that:
▪
the water treatment is correctly executed by a qualified water specialist,
▪
a glycol with corrosion inhibitors is selected to counteract acids formed by the
oxidation of glycols,
▪
no automotive glycol is used because their corrosion inhibitors have a limited
lifetime and contain silicates which can foul or plug the system,
▪
galvanized pipes are NOT used in glycol systems since the presence may lead to
the precipitation of certain components in the glycol's corrosion inhibitor.
