Voigtländer · Technology
Disinfectant produced on site with the Voigtländer g4000 generator
Voigtländer generates the active substance where it is used: from water, salt and electricity, dosed under control and measured continuously. This page explains the technology; the application pages show what it does for each sector.
- DIN EN 901 · § 11 TrinkwV (German Drinking Water Ordinance)
- DVGW W551
- TrinkwV approval (Umweltbundesamt, the German Environment Agency)
- WHO-compliant
- CE conformity

The generator
A three-chamber generator turns water, salt and electricity into anolyte
The Voigtländer g4000 generator produces anolyte, hypochlorous acid (HOCl), on site from water, salt and electricity. There is no chlorine gas to store or transport, and no chlorine dioxide precursor store. The active substance is made at the point of use, as needed, and dosed under control into the intended water path.
The process is not described in absolute terms about chlorine or about chemicals in general. Salt is an input to the generator, not something the process avoids.
The process
From generator to dosing point, measured throughout
Inlet and water meter, brine tank, the three-chamber generator, anolyte tank, demand-led dosing, measurement and control: seven stages in 34 seconds. Press "Show me the process" to start the animated 3D diagram.
Modelled from the Voigtländer plant schematic of an anolyte system, in the drawing language of the home page. The cards show documented facts only, no invented figures.
In the plant
Seen in operation
Short clips from a Voigtländer installation at an airport: the plant room with the g4000 generator, a chlorine controller reading in operation, and the aircraft drinking water bay.
What makes it different
Generated on site, dosed to measurement, kept traceable
Generated on site
The active substance is produced at the point of use instead of storing and transporting chlorine gas or chlorine dioxide precursors.
Dosed under measurement
Dosing follows measured values, not a fixed schedule, and is integrated into the existing water path or cleaning sequence.
Measured and traceable
Water quality is measured continuously, so operation stays traceable for HACCP, audits and regulatory evidence.
Where it is used
One generator technology, four application areas
The g4000 generator is the same across sectors; the application pages describe how it is integrated into each specific water path and what the sector-specific requirements are.
Buildings: Legionella remediation
Anolyte dosed into the drinking water installation, without a chlorine dioxide store, with continuous measurement and documentation.
View the buildings application page ›Aviation: aircraft drinking water
Continuous, monitored drinking water hygiene from storage tank to aircraft, without chlorine gas logistics.
View the aviation application page ›Food and beverage: CIP and process hygiene
Anolyte integrated into the existing CIP cleaning sequence for shorter, validated cycles.
View the CIP application page ›Cooling systems: cooling tower Legionella
On-site generation and measurement-led dosing for evaporative cooling systems and cooling towers under the 42. BImSchV.

Application
Where the g4000 generator is in operation
Frankfurt Airport has run a Voigtländer system since 2003. The case study describes the integration of a g4000 generator, controlled on-site generation, monitoring and documentation.

Airports and care homes in operation
Macau Airport
Anolyte produced on site, the complete system in a 20-foot container.
View the Macau Airport reference ›Saarbrücken Airport
Anolyte dosed into the mains water, about 10 m³ of drinking water a day.
View the Saarbrücken Airport reference ›Ten care homes, one drinking water programme
Ten care homes kept failing the drinking water regulations despite thermal disinfection. After a month of testing, the systems went into every home.
