W100W Controllers - Plug into more options in water treatment control!
For Cooling Tower/Boiler,Conductivity, pH/ORP and Disinfection

Three powerful control outputs make the Walchem W100W a more versatile, high value choice among entry level water treatment controllers. The W100W series provide an economical and reliable way to keep your water treatment program under control. Universal sensor input provides extraordinary flexibility; the same controller can be used with almost any type of sensor needed.


Cooling Tower

WCT/WDT
Low cost, reliable control of 1 or 2 cooling towers. Up to 2 direct sensor inputs (conductivity and either pH or ORP) and 6 relays available. Multiple feed modes and dual biocide additions.
WebMaster (WMT)
Online cooling tower controller with 8 relays, up to 4 direct sensor inputs, 8 analog inputs, 12 digital inputs, local/remote communications, data logging and email/text message alarms. Handles multiple towers, boilers, closed loops or any combination.
   

Disinfection

WDIS
Reliably and economically control your water treatment disinfection process. Select from free chlorine, chlorine dioxide, ozone or peracetic acid sensors or configure to use a variety of other disinfection sensors.
