In our nt-BlueBox the complete electrolysis and adjusted dosage is pre-installed in a very compact form. The concentration of the disinfectants in the tap water is monitored by a measuring bypass. The nt-BlueBox product range has different production capacities of sodium hypochlorite, starting from 3g/h, 5g/h, 12g/h, 30g/h, 60g/h, 90g/h, 150g/h, 200g/h und 300g/h.

Special features of the nt-BlueBox


  • Proven to be effective against Legionella in water and biofilms in pipes, even at low concentrations of 0.3mg/L during long-term disinfection

  • No loss of effectiveness by avoiding transportation and storage of disinfection chemicals

  • minimized formation of disinfection by-products


  • nt-BlueBox generates low concentrated sodium hypochlorite solution (up to 0.6%),

  • which is on-site produced when needed from common salt and water and dosed.

  • this avoids the usage of hazardous substances that must be labelled and replaced by the less hazardous 0,6% NaClO according to the EU-regulation

Compact and mobile

  • plug & play after pre-installation in the factory

  • including dosing, measuring bypass and online monitoring

  • also suitable for mobile applications


  • for shock disinfection

  • for long-term disinfection

  • for both hot and cold water disinfection

Environmental friendly

  • No transport, no storage, no handling and no disposal of hazardous chemicals

  • Very low energy consumption

  • NaClO solution up to 0.8% is biodegradable
