Dosatron International offers the DIA 4 RE, water powered dosing technology. Installed directly in the water supply line, Dosatron is activated by water flow, which mixes with the concentrate inside the unit and uses water pressure to force the solution downstream. The DIA 4 RE features a volumetric hydraulic diaphragm motor, continuous injection of liquid or soluble concentrate, proportionality servo-controlled by water flow and integrated mixing.
