WCT410 SERIES The WCT410 series takes the features of the WCT400 and adds more. These controllers also have a dual programmable biocide addition capability. The biocides can be added several times per day, or on a weekly, two week, or a four-week cycle. If you feed inhibitor based on a water meter contact input, the WCT410 will totalize the makeup flow, so you don't have to climb the rafters to read the register on the water meter. |

The WDT400/410 Cooling Tower Controllers represent the latest in technological and innovative advancements from Walchem. 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 WDT400/410 controllers have the ability to store conductivity, pH/ORP, 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. |
