A Fully Integrated Controller 

The CHEMTROL® CT6000 controller is a fully integrated controller designed for complete chemical automation (Conductivity, pH and ORP), control of chemical additives (inhibitors, biocides, dispersants, etc.), water level, and automatic filter backwash control in cooling towers, boilers, and waste water, all with full remote duplex capability.

The user-friendly eight-line Main Screen display enables the operator to supervise all the process functions at a glance and to quickly respond to any changing condition with choice of operating language (English, French and Spanish) and units (US or metric). Entries are made on the 16-key keypad on the front panel.  Each unit is supplied with a comprehensive instruction manual with schematics of installation and menu flow charts.

CT6000 Installation

Installation of the CHEMTROL® CT6000 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® CT6000 with a Bypass line assembly manifold.

CT6000 Operation

The CHEMTROL® CT6000 controller operates like a computer with full-screen displays 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 set-points, alarm levels and the different feed programs.

Remote Monitoring & Control

Our range of programmable controllers all have remote access capability, so you can control and monitor your facility 24/7.

With the remote operation function any number of facilities can be controlled and monitored from your computer, or via our mobile App. From a computer simply login directly via your browser using our web-server where the controller display is mirrored on your computer.

True duplex operation that allows real-time control and troubleshooting of all operating functions, including status reports, trend graphs and automatic alerts by email or text messages. You can also access and control your controller via our dedicated app, available for Android and Apple devices.

In terms of connecting your controller, this can be achieved via a wired Ethernet cable, WIFI signal, or by using a wireless connection with a compatible 4G or 5G router.
