Scaling is caused by a mineral film that coats the heat exchanger surface. The typical form of scale is from calcium-based salts. These are reverse soluble salts which means that when the temperature increases their solubility decreases – contrary to most salts. When the water containing these salts is heated in the heat exchanger the salts begin to plate out on the heat transfer surface forming a mineral deposit. When this happens the heat transfer efficiency quickly decreases because the mineral deposit is a highly insulating thermal barrier.



Our coating creates a very smooth and dense barrier that prevents the mineral growth formation on the heat transfer surface. The coating is very thin and will not inflict on the heat transfer coefficient. It consists only of silicon and oxygen and is non-toxic. The result is a heat exchanger that can operate at elevated temperatures, for much longer times, that requires a minimum of maintenance.
