Hadex Chlorinating dosing unit

Secure your drinking water system with a fully automatic flow-controlled Hadex® Dosing Unit. Our Hadex® disinfection treatment reduces and prevents the growth of bacteria, algae, and other microorganisms. As with any disinfectant, the correct dosage is essential for proper functioning.

Hadex® automatic dosing units are available for 10 and 25-liter Hadex® cans. The units are proportionally controlled by pulse-generating flow meters. All dosing units can be customized according to your own specifications. A major advantage of our HDU is its standard packing, which is designed to be used as a dosing container, making it safer and easy to use.


For larger flows, especially in bunker systems, electromagnetic flow meters are available too. These meters have no moving parts.

The dosing units can also be controlled based on free chlorine concentration. For this, an inline chlorine measurement unit is integrated. Contact our Sales Engineers for information on a possible configuration for your situation.

Hadex® dosing units are commonly used for three points in the fresh water system:

  • In the water maker product line
  • In the fresh water bunker line
  • After the hydrophore pumps (for re-chlorination of the distribution system)
