What is EXAGEN, and what is it used for?

EXAGEN is a liquid disinfectant concentrate against waterborne germs. On contact with water it forms chlorine dioxide in situ, for combating waterborne germs, including Legionella, E. coli and Pseudomonas, and biofilms.

Areas of use are the disinfection of pipes, containers and tanks, drinking water distribution systems, dispensing systems and dental units. EXAGEN contains no silver and no copper.

After use, the system is rinsed out completely: chlorine dioxide and the second chlorine-oxide component are each permitted individually in the Trinkwasserverordnung (German Drinking Water Ordinance), but their mixture is not.
