Walchem's WDIS Series controller will reliably and economically control your water treatment disinfection process.The controller includes four standard sensor input options (free chlorine/bromine, chlorine dioxide, ozone and peracetic acid) or can be configured to use a variety of other types of disinfection sensors such as hydrogen peroxide or total chlorine. The WDIS Series controller takes the guesswork out of your disinfection process. The chemical concentration is continuously monitored and controlled to the precise range required for proper system control and regulatory compliance.
Designed to be flexible and versatile, the WDIS series controller is the ideal solution for disinfection applications in cooling towers, food and beverage, drinking water, wastewater and swimming pools.
Integrated datalogging is available to validate system performance. A USB memory stick is all that's needed to extract data and event logs that include disinfection sensor measurements and relay status. Download log files from the USB stick to a PC at your convenience. It couldn't be easier!
Summary of Benefits:
Versatility for a Broad Range of Applications
Choose from four industrial grade sensors in one controller - chlorine/bromine, chlorine dioxide, ozone, peracetic acid or configure the controller to use a variety of other sensors. Relays can be configured for Hi Alarm, Low Alarm, Out-of-Range Alarm, In-Range Output or Probe Wash, providing unmatched flexibility.
Economical and Simple to Use
WDIS controllers are economically priced and do not require any costly reagents. The rugged NEMA 4X enclosure and panel mounted flow assembly has only two process connections for quick and easy installation.
Built-in Safety Features
Programmable output limit timers prevent run-away chemical addition. Digital Interlock Input may be used from a flow switch or level input to prevent chemical addition based on a stagnant sample, or control of an empty batch tank. The alarm relay notifies plant personnel of alarm conditions as soon as they occur.
Simple, Integrated Data Collection
Download stored data from the controller to a USB stick. Use the data to simply and easily validate system performance, document compliance and reduce liability. The data and event logs logs show disinfection levels, as well as accumulated chemical feed and relay activation times.
