WCT/WDT400 Cooling Tower Controllers
The WCT/WDT400 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 WDT400 Controllers have the ability to store conductivity, pH/ORP 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!
Key benefits
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 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.
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!
