DeCalon DCI 

DeCalonTM (DCI) uses electro-chemistry and a patented intelligent controller to remove water hardness from cooling systems without the need for hazardous chemicals. The result is a green technology solution to scaling and corrosion in large building HVAC systems and industrial chiller circuits. Below are a few of the benefits of using the DeCalon.

  • Zero Chemicals

  • Up to 10% - 25% Less Energy Usage

  • Up to 50% in Water Savings

  • Removes existing scale from the system

  • Easy Installation with no outage required
