CDG – Chlorine Dioxide Generators


Chlorine dioxide is an extremely effective water disinfectant against all types of pathogens, and also destroys biofilms, thus eliminating the source of nourishment for microorganisms and therefore preventing their growing. Moreover, its disinfectant capacity does not depend on the water pH level.

It is used in water purification processes, in the disinfection of sanitary water systems and water for food industry and other processes.

The main disadvantage of chlorine dioxide is its instability; in fact, it is a very reactive gas, which must be produced on site.

The CDG generator has been designed to produce chlorine dioxide in aqueous solution and store it in a storage tanks, for subsequent controlled dosing.

A PLC equipped with touch-screen allows a simple and intuitive interaction with the entire system, all configuration operations, start-up and stop of the unit, choice of the operating mode and error management.

In addition, the system includes various safety controls, such as level sensors, flow controls and chlorine dioxide gas sensor in air.
