Chemtrol - Model CT110 -Cooling Tower Controller
CHEMTROL® CT110 controller is an easy-to-use but sophisticated programmable controller designed for control of conductivity (Total Dissolved Solids) and programmable addition of chemical additives – such as inhibitors, biocides, dispersants, etc. pH control with display of the Langelier Saturation Index (LSI) is recommended as an option. Applications include cooling towers, boilers, and other industrial water applications. It is easy to install and operate. All menus are displayed on the LCD graphic display screen. Entries are easily made with the 5 keys conveniently located on the front panel. Each unit is supplied with a comprehensive instruction manual with schematics of installation and menu flow charts.

Installation of the CHEMTROL® CT110 controller is quite simple, as shown on the schematics below. To further facilitate installation, every controller comes with a detailed instruction and operation manual.
To assure proper water sampling and sensor performance, it is highly recommended to install the CHEMTROL® CT110 with a Bypass line assembly manifold.
The CHEMTROL® CT110 controller operates like a computer with an LCD screen display and direct access to all menus and submenus. The front panel keypad is used to move up and down each menu and enter or exit the submenus. All operating functions can be easily modified from the keypad, including sensor calibration, control setpoints, alarm levels and the different feed programs.
