Chlorine dioxide system Legio Zon®

With Legio Zon®, 0-5 g/h of chlorine dioxide are generated by the chlorite/acid process and dosed in proportion to volume.

Advantages

Outstanding Legionella protection with the proven chlorite/acid process for small and mid-sized buildings too.
High safety standard in accordance with DVGW (German Gas and Water Association) specification W 224 and no hazardous operating conditions, thanks to optimal
chlorine dioxide concentration (2 g/l)
High operational safety through automatic monitoring functions and service messages
Low investment costs, simple and low-cost maintenance
Simple operation

Features

0-5 g/h chlorine dioxide generation in batch process mode
Equally suitable for continuous and intermittent operation
High stability of the generated chlorine dioxide solution lasting over several days
Safe automatic restart after mains failure
Controller with menu-guided operation, rinse and service functions
Integrated dosing pump for chlorine dioxide
Direct control by means of contact water meter or inductive flowmeter
