W400 Cooling Tower Controllers
The W400 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 W400 Controllers have the ability to store sensor and temperature values, water usage, relay 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!
WECT/EDT Controllers include an electrodeless conductivity sensor that's impervious to contamination by oils, scale, biofilm or other coatings, resulting in a low maintenance system that provides reliable effective control.
Ensure 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 validate and verify water treatment results, and include actual water usage, system conductivity, temperature and accumulated chemical feed and bleed times.
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.
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!
