The Next Generation of Powerful Control!

Connect with the Walchem W900 Series controllers and enjoy unparalleled versatility in maintaining your water treatment options.

Now with expanded new capabilities:

  • Powerful Control
  • Flexible Programming
  • Online Access
  • Easy Setup
  • Great Value

Summary of Key Benefits:

  • Large touchscreen display with icon based programming makes setup easy
  • Universal sensor input provides extraordinary flexibility; the same controller can be used with almost
    any type of sensor needed
  • Four I/O slots allow complete flexibility in adding additional sensors, analog inputs and analog outputs
  • Multiple language support allows simple setup
  • Eight relay control outputs allow the controller to be used in more applications
  • Economical wall-mount package for easy installation
  • On-screen and web page graphing of sensor values and control output status
  • Complete flexibility in the function of each relay:
    • On/Off Setpoint
    • Time Proportional Control
    • Pulse Proportional Control (when purchased with 4-20 mA or pulse solid state opto outputs)
    • Flow Proportional Control (when purchased with 4-20 mA or pulse solid state opto outputs)
    • PID control (when purchased with 4-20 mA or pulse solid state opto outputs)
    • In-Range or Out-of-Range activation
    • Probe wash
    • Timer-based activation
    • Activation based upon the state of a contact closure
    • Timed activation triggered by Water Contactor / Paddlewheel flow meter’s accumulated total flow
    • Activate with another output
    • Activate as a percent of another output’s on-time
    • Alarm
    • Spike Set Point
    • PPM Volume
    • Target PPM
    • For Cooling Tower and Boiler applications:
    • Biocide Timer
    • Boiler blowdown on conductivity using intermittent sampling
  • Datalogging
  • Email Alarm messages, Datalog reports or System Summary reports
  • Ethernet for remote access via the Internet, LAN or optional Modbus/TCP
