Chemical Dosing Units

Safely treat on board water with chemicals.

Fresh water and service water on board of ships is necessarily taken from various sources. To compensate the varying water quality, the water has to be treated with chemicals.

With RWO dosing units you can easily and reliably condition the water to serve the intended use and to meet the technical requirements. 
RWO dosing units feature solenoid driven diaphragm metering pumps. The combination of solenoid drive and diaphragm guarantees durability and dosing accuracy. All parts in contact with media are chosen for their resistance against the standard chemicals used for water treatment. 
The control of the pump allows a continuous adjustment of injection volume and frequency. This guarantees an adaptation to the dosing characteristics of the dosing agents.
