WECT400/410 | Cooling Tower Controllers An Iwaki America Company OVERVIEW The WECT400/410 Cooling Tower Controllers with electrodeless (toroidal) conductivity sensors represent the latest in technological and innovative advancements from Walchem. The electrodeless sensor is impervious to contamination by oils, scale, biofilm, or other coatings, resulting in a low maintenance system that provides reliable, effective control. All of the standard features you’d expect in 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 WECT400/410 controllers have the ability to store conductivity 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 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. $ Spend More Time Selling Electrodeless conductivity sensor is impervious to contamination and coatings, which means you’ll spend less time cleaning and calibrating sensors and spend more time selling! 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!
