Chemical Dosing and Control System for Cooling Water Circuit
Cooling Water will recycle during operation of Cooling Tower and due to evaporation the Conductivity (Total Dissolved Solids, TDS) of Condenser Water will increase (Concentration of dissolved ions exceeding mainly due to evaporation).
The main objective is to control the Concentration of dissolved ions in Cooling Water.
So, when dissolved ions exceed the preset Conductivity level, the installed Conductivity Controller activates the Solenoid Bleed Off Valve on automatic mode and highly Concentrated Cooling Water will drain out, until the low limit of Conductivity is achieved.
All of the above is strongly recommended to avoid high concentration of dissolved ions in Condenser Water and control the recommend parameters.
System will include the following:
-
Conductivity Controller
-
pH Control System
-
Automatic Chemical Dosing System
-
Bypass Feeder for Chilled Water
