Cooling Towers and Boiler Conductivity Controllers
WCT Series, Cooling Tower Conductivity Controllers
Walchem WCT Series cooling tower conductivity controllers are the ultimate cooling tower conductivity controllers. WCT Series controllers automate bleeding  water at high solids and add make-up water, helping maintain a proper conductivity level. Additionally, WCT controllers can limit corrosion, solids precipitation, and scale build-up by simultaneous control of chemical feeds. The WCT310 model offers an additional feature; automatic addition of biocide to prevent growth of algae and bacteria.Features:
WBL Series Boiler Conductivity Controllers and WCM Series Condensate Monitors
Walchem WBL Series controllers automatically discharge high solids water and adds make-up water keeping boiler water at the right conductivity level. The WCM Series condensate monitor watches the conductivity of the boiler's condensate. When the conductivity of the condensate exceeds an operator set level a diverter valve is opened or an alarm sounds, or both. 
WCM300 Condensate Monitor Features
WBL Series Boiler Conductivity Controller Features
WDT Series Cooling Tower Dual Input Conductivity Controllers
Walchem WDT Series dual input controllers are used for water treatment of cooling towers. Dual inputs improve accuracy and reliability. Model WDT300 enables monitoring of two cooling towers. Output relays activate system bleed and chemical feed for each input channel. Model WDT310 controls one cooling tower's conductivity with inhibitor feed, two biocide feeds, plus either pH or ORP control. Features include:
WDB / WDC Series Boiler Dual Input Conductivity Controllers and Dual Input Condensate Monitors
Walchem WDB / WDC Series dual input boiler controllers and dual input condensate monitors ensure optimal performance in boiler applications. A WDB controller can manage the conductivity of two boilers under 250 psig with its dual controllers. Additionally the condensate monitors watch the boilers condensate and can automatically divert contaminated condensate. Features include:
Specialty Controllers
WCU Series Copper Controllers
 Walchem WCU Series copper controllers are optoelectronic on-line analyzers that measure copper concentration in a fluid. The fiberoptic detection method provides stable and accurate measurement of metal concentration. Two common applications are electroless copper plating and microtech baths. Benefits of copper controllers include:
WNI Series Nickel Controllers
Walchem WNI Series electroless nickel controllers offer excellent nickel process control. WNI Series nickel controllers are optoelectronic on-line analyzers that measure nickel concentration in a fluid. The fiberoptic detection method provides stable and accurate measurement of metal concentration. WNI controllers have a flow through out-of-tank sensor mounting style that conserves tank space and does not require degassing. Benefits of nickel controllers in an electroless plating bath include:
WEC Series Non-Contacting (Toroidal) Conductivity Controllers
Walchem WEC Series non-contacting conductivity controllers are versatile and cost-effective. WEC Series controllers measure a fluids conductivity through an encapsulated non-contacting sensor. The sensor measures accurately over a wide dynamic range and is appropriate for applications 50µS/cm to 1000 mS/cm. WCM controllers are available in single and dual input versions. Chemical control applications include:Metering Pumps
