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. With a USB memory stick data and event logs that include disinfection sensor measurements and relay status can be extracted. Then
