Hadex Dosing units

Hadex® Dosing units help you to keep your drinking water clean and safe by automating the dosing of our Hadex® disinfection. Especially suitable when you need larger quantities of water.

The units are controlled by pulse generating flow meters. Electromagnetic flow meters are also available for larger flows, especially in bunker systems. These meters have no moving parts. The dosing units can also be controlled based on free Hadex concentration. An in-line Hadex measuring unit is integrated for this. All dosing units can be adapted to your own specifications. Hadex® automatic dosing units use the 10- and 25-liter Hadex® drinking water disinfection cans. Our Hadex disinfection treatment reduces and prevents the growth of bacteria, algae and other microorganisms.
