1.CONDUCTIVITY. A conductivity reading is taken - when this reading is higher than the level set, the auxiliary output opens a solenoid valve drawing off polluted water from the cooling tower. This solenoid valve will close when the conductivity value is equal to the set point.

2.INHIBITOR. An Inhibitor dosing pump for the re-integration of make up water is connected to a water meter with pulse emitter.

3. BIOCIDE. The Biocide dosing pump is time controlled and is activated by a daily/weekly electronic timer.
