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. The WECT/WEDT controllers have the ability to store conductivity, pH/ORP and temperature , values, water usage, relay and flow switch status, and user settings. A USB 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 from another controller to speed start-up. It couldn’t be easier! 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. Spend More Time Selling Electrodeless conductivity sensor is almost immune to contamination and coatings, which means you’ll spend less time cleaning and calibrating sensors and spend more time selling! 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 Efficient Customer Service Quickly identify system upsets by knowing exactly what happened and when. An event log can be downloaded to tell you precisely when pumps turned on, valves opened, and when there was flow or no-flow. More Informative Monthly Reports Download stored data from the controller to a USB flash stick. Use the data to easily develop reports that validate and verify water treatment results, and include actual water usage, system conductivity, temperature, and accumulated chemical feed and bleed times. Save Time Copy the user settings from your controller to a USB flash stick and upload to a new controller. Programming your new controller this way can be accomplished in seconds. It’s that simple! Note: For EN61000-4-6 & EN61000-4-3 the controller met performance criteria B. *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. 180460.I May 2014 All of the standard features you’d expect in a conventional cooling tower controller are included, plus simple-to-use information management tools that enable water treatment professionals to deliver more effective service to their customers.
