An Iwaki America Company WCT400/410 | Cooling Tower Controllers OVERVIEW The WCT400/410 Cooling Tower Controllers represent the latest in technological and innovative advancements from Walchem. All of the standard features you’d expect from a conventional cooling tower controller are included, plus optional simple-to-use information management tools that enable water treatment professionals to deliver more effective service to their customers. The WCT400/410 controllers have the ability to store conductivity 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 $ 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. 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. NT WATER TREATME RESULTS Validation and Verification Made Easy Use stored data from the controller to simply and easily validate water treatment results. The data and event logs show water usage, system conductivity, and temperature, as well as 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!
