PC5000 Installation 

In our commitment to simplify the installation process of CHEMTROL® controllers, we have streamlined everything onto a customized assembly manifold, prepared for easy connection.
This approach ensures proper water sampling around the sensors, facilitating a hassle-free installation that minimizes the integration work required to get your water treatment system operational.


PC5000 – Bypass line assembly

Chlorine sensor (ppm) with integrated pH, ORP, and TDS control

Seamless controller setup: Choose between hardwired dosing pumps or General Purpose Outlets (GPOs) for easy dosing equipment connection.

Our Flow Cell Assembly (FCA) features a clear acrylic flow cell for Chlorine sensor (ppm), 2 flow control valves, a water sample valve, safety flow switch, and probes holder fitting.

The Controller assembly includes a grey PVC backboard (600×400 mm), while the By-pass line assembly features a grey PVC backboard (600×500 mm).


PC5000 Operation

The CHEMTROL® Programmable Controller range provides comprehensive control and monitoring capabilities through its user-friendly interface. Here’s a breakdown of its key features:

Main Display Screen: The main screen offers direct access to all menus and submenus, allowing easy navigation using the four directional arrow keys and a ten-key keypad for numerical settings.

SANITIZER MENU: Used for controlling chlorine or bromine levels with an amperometric sensor. This menu allows the selection of control mode, sensor calibration setpoint level, and high and low alarms. Additionally, it displays runtime information and enables manual or scheduled super chlorination treatments.

pH MENU: Similar to the SANITIZER MENU, this menu selects pH control parameters using acid or base feed. It also includes an Acid Wash program for periodic sensor maintenance.

ORP MENU: This menu allows for the selection of control mode, sensor calibration, setpoint level, high and low alarms, shocking, and chemical saver programs related to Oxidation-Reduction Potential (ORP). It also displays run time information and enables manual or scheduled super chlorination treatments treatments.

SATURATION and WATER BALANCE: Ensures proper control of saturation and water balance to maintain water quality and prevent scaling or corrosive conditions.

TDS MENU: Sets automatic dumping of water when dissolved solid concentrations are high. It includes options for Conductivity or TDS control setpoints to activate the dump valve.

Langelier Index: Calculates the saturation condition based on pH, Temperature, Alkalinity, and Calcium Hardness. Constantly displayed on the Main Screen, it alerts to potential scaling or corrosive conditions.

TEMPERATURE / HEATER CONTROL: Displays temperature sensor readings and controls the heater. The TEMPERATURE MENU allows setting the heater control to Manual or Automatic with a programmable seven-day schedule.

PUMP AND FILTER CONTROL: Provides manual or programmable operation of the main recirculation pump and backwashing cycle, ensuring efficient filtration and protection of the heater.

SETUP MENU: Allows modification of configuration parameters for initialization, operations, and communications, providing flexibility to adapt to changing needs.

The CHEMTROL® Programmable Controller range stands as a powerful and versatile solution for effectively managing water quality in commercial facilities. With advanced control and customization options, it provides a comprehensive and adaptable system for precise water quality management.
