Controller AEGIS S

AEGIS S is an easy-to-use water treatment controller for evaporative cooling systems. It is designed to keep the cooling process running reliably. AEGIS S measures conductivity and controls dosing of biocides and corrosion inhibitor, thus preventing biological growth and keeping pipelines and heat exchangers clean.

Smart and Powerful for Your Cooling System: Controller AEGIS S

AEGIS S is an easy-to-use water treatment controller for evaporative cooling systems. With AEGIS S, users can easily monitor and control their process parameters with accuracy and reliability, helping to ensure an optimal cooling process.

Thanks to time- or measurement-based biocide metering and monitoring of electrolytic conductivity, AEGIS S prevents biological growth, keeping pipelines and heat exchangers clean.

The controller’s features include an intuitive user interface with touch display and live view of the animated cooling circuit with measured values and display of the process status.

AEGIS S enables economical operation through timers for winter/summer and weekdays, automatic reporting as well as other user-supporting functions, such as an integrated maintenance calendar. Its flexible communication options facilitate efficient and reliable data exchange.
