ProMinent Legio Zon® Series

ProMinent® Legio Zon® Series

Zero Tolerance for Legionella!
Chlorine dioxide is rapidly gaining acceptance, particularly in the control of Legionella and other bacteria in potable water used in public buildings such as hospitals, hotels or healthcare facilities. With the new ProMinent® Legio Zon® system, the requirements of smaller and midsized buildings can be reliably handled.

ProMinent® Legio Zon® can generate up to 10 g/h of chlorine dioxide and can dose in proportion to the flow of the water source. The intelligent operation and maintenance concept enables safe, simple and reliable operation, as well as easy and cost-effective maintenance. The total process management system is also suitable for intermittent operation.
