Electrolysis System CHLORINSITU IIa XL

Output 5 – 45 kg/h of chlorine

CHLORINSITU IIa XL is the tubular cell electrolysis system for on-site production of large quantities of hypochlorite. Users cannot fail to be impressed by its ease of operation and outstanding efficiency combined with optimum process stability for the reliable disinfection of large volumetric flows.

High-Performance Open Cell Electrolysis

The new CHLORINSITU IIa XL is specially developed to meet the requirements of large-capacity in-situ potable water disinfection. Based on the robust tubular cells, the system is a modular system for the safe production of hypochlorite solution from a diluted salt solution. Thanks to its precise production and optimised cell design, it achieves a high turnover of salt at a concentration of 8 g/l in the final product. The certified safety concept ensures the safe extraction of hydrogen and maximum operating safety. The CIIa XL is combined with the necessary modules, depending on the needs of the project, and is adapted as best as possible to the conditions on-site.
