The DeCalon Device

DeCalonTM (DCI) is a revolutionary approach to eliminating scale in cooling water systems. Through applied electro-chemistry and a patented intelligent controller DCI removes water hardness from cooling systems without the need for hazardous chemicals. The innovation provides a green technology solution to scaling and corrosion in large building HVAC systems and industrial chiller circuits.

The DCI system removes existing scale deposits and prevents further scale formation by driving a non-spontaneous redox reaction which precipitates CaCO3 and Mg(OH)2  at the cathode. The main causes of scaling, Ca2+ and Mg2+, can then be dumped out of the recirculating cooling water. SiO2 is also removed. The system operates continuously so design heat transfer efficiency is maintained at all times and the non-regulatory requirement for routine shut downs for cleaning is removed. Water blow-down quantities are also reduced.
