WIND has a flexible multi-I/O platform, a wide range of analytical sensor measurement capabilities, and an extensive assortment of integrated communications and data handling features. AGENCY CERTIFICATIONS Safety EMC Walchem’s WebAlert is the first stand alone remote monitoring device that can web enable your installed equipment without having to replace or upgrade it. Designed to be flexible and versatile, the WDIS Series controller is the ideal solution for disinfection applications in cooling towers, food & 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. Summary of Key Benefits Versatility for a Broad Range of Applications Choose from four standard industrial grade sensors in one controller (chlorine/bromine, chlorine dioxide, ozone, peracetic acid) or configure the controller to use a variety of other disinfection sensors. Relays can be configured for Hi Alarm, Low Alarm, Out-of-Range Alarm, In-Range Output or Probe Wash, providing unmatched flexibility. ABOUT US Walchem integrates its advanced sensing, instrumentation, fluid pumping and communications technologies to deliver reliable and innovative solutions to the global water treatment market. Our in-house engineering is driven by quality, technology and innovation. For more information on the entire Walchem product line, visit: www.walchem.com Note: For EN61000-4-6 & EN61000-4-3 the controller met performance criteria B. 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 show disinfection levels, as well as accumulated chemical feed and relay activation times. *Class A equipment: Equipment suitable for use in establishments other than domestic, and those directly connected to a low voltage (100-240 VAC) power supply network which supplies buildings used for domestic purposes. 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. WebAlert® Remote Monitor USB FEATURES U = Integrated datalogging, event/reset logging, and configuration file import/export Note: Refer to the Disinfection Sensor brochure for additional sensor options. Order the WDIS controller with sensor option “N” then order the appropriate sensor separately. 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, peracetic acid) or can be configured to use a variety of other types or ranges of Walchem disinfection sensors, such as hydrogen peroxide or total chlorine.
