An Iwaki America Company WBL/WCM400 | Boiler Controllers/Condensate Montiors OVERVIEW The WBL400 Boiler Controllers and WCM400 Condensate Monitors represent the latest in technological and innovative advancements from Walchem. All of the standard features you’d expect in conventional boiler controllers/condensate monitors are included, plus optional simple-to-use information management tools that enable water treatment professionals to deliver more effective service to their customers. The WBL/WCM400 controllers have the ability to store conductivity 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! SUMMARY OF KEY BENEFITS Ensures Optimal Performance and Maximum Efficiency Precise control of conductivity and chemical feed inhibits corrosion, solids precipitation and scale build-up. Unique time proportional blowdown feature saves energy by reducing water consumption. $ 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 the boiler was offline. T WATER TREATMEN RESULTS 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 blowdown 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!

WBL/WCM Series | Boiler Conductivity Controller / Boiler Condensate Monitor Choice of measurement units • To customize your control or complement your calibration procedures, conductivity may be displayed as μS or PPM; temperature as °F or °C. Choices of blowdown modes for timed samples • In intermittent sampling, the blowdown valve is open until the set point conductivity is reached. • In intermittent with timed blowdown, the blowdown valve opens for a set programmable time. Four chemical feed options • Feed & blowdown simultaneously, with or without feed lockout timer • Feed after blowdown...
