Hadex Dosing units
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 micro-organisms. As with any disinfectant, the correct dosage is essential for proper functioning.
Hadex® automatic dosing units are available for 10 and 25 litre Hadex® cans. The units are proportionally controlled by pulse generating flow meters. All dosing units can be customised 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.
|Part number||Flowmeter||Capacity nominal||Capacity Maximal|
|(inch / mm)||(Qn m3/hr @ ΔP 0,25 bar)||(Qmax m3/hr @ ΔP)|
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 on base of free chlorine concentration. For this, an in-line chlorine measurement unit is integrated. Contact our Sales Engineers for information on a possible configuration for your situation.
Hadex® dosing units are commonly used at three freshwater system points:
- In the watermaker product line
- In the freshwater bunker line
- After the hydrophore pumps (for re-chlorination of the distribution system)

In which conditions do I need to store my Hadex supply in order to ensure its maximum shelf life?
Hadex® should be kept indoors, in a cool and dry (dark) area. If stored at temperatures below 25°C, it can be stored for up to 1.5 years without losing its effectiveness. If stored in really cool termperatures (t = < 6 °C) it will even keep for up to 3 years.
