WIND WebMaster® Industrial Water Controllers Walchem’s WebMaster Industrial (WIND) Controller sets a new standard for Industrial Water Treatment Controllers. 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. WCT/WDT400 Series The WCT/WDT Cooling Tower Controllers represent the latest in technological and innovative advancements from Walchem. All of the standard features you’d expect in a conventional cooling tower controller are included, plus simple-touse information management tools that enable water treatment professionals to deliver more effective service to their customers. The WCT/WDT controllers have the ability to store conductivity, pH/ORP , and temperature values, water usage, relay and flow switch status, and user settings. A USB memory stick is all that’s needed to extract the information. Download logs from the USB stick to a PC at your convenience, or copy your preferred treatment program settings to another controller to speed start-up. It couldn’t be easier! Summary of Key Benefits WebAlert® Remote Monitor 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. Ensures Optimal Performance and Maximum Efficiency Precise control of conductivity and chemical feed reduces water consumption and inhibits corrosion, solids precipitation, scale build-up, and growth of algae or dangerous bacteria. More Informative Monthly Reports Download stored data from the controller to a USB flash stick. Use the data to easily develop reports that show actual water usage, system conductivity, temperature, and more. AGENCY CERTIFICATIONS Safety: Note: For EN61000-4-6, EN61000-4-3 the controller met performance criteria B. This equipment is 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. 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 180457.H May 2014 Walchem, Iwaki America Inc.
