WCT/WDT Cooling Tower Controllers

Walchem offers a variety of on-line controllers for your cooling tower applications.  With a choice of two different NEMA 4X models, WDT300/310 (Dual Input Cooling Tower) or WCT300/310 (Single Input Cooling Tower), finding the perfect fit for your cooling tower is simple.

The WDT300 Series can control conductivity (bleed and feed) for two independent towers. The WDT310 Series is equipped to control conductivity, pH (or ORP) and programmable dual biocide outputs for a single tower. The WCT300 is a single tower, feed/bleed, conductivity controller and the WCT310 adds a programmable dual biocide output option. All Walchem cooling tower controllers are microprocessor-based with an easy-to-use menu format for programming.  UL/CSA/CE certified.
