WCT/WDT Controller

Cooling Tower Controller

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.

The W400 Cooling Tower Controllers have the ability to store sensor and temperature values, water usage, relay status, and user settings. A USB memory stick is all that’s needed to extract the information.

WECT/EDT Controllers include an electrodeless conductivity sensor that’s impervious to contamination by oils, scale, biofilm or other coatings, resulting in a low maintenance system that provides reliable effective control.

  • Four chemical feed options
    • Feed & bleed, with or without feed lockout timer
    • Feed after bleed has finished, as % of time
    • Feed as a percentage of time elapsed
    • Feed as a percentage of make-up water
  • Conductivity Electrodes
    • Graphite or stainless steel
    • Low pressure or high pressure
    • In-line or submersion
  • Self-Diagnostics
    • Software, electronics, and sensor are constantly monitored without having to take controller offline.
  • Optional isolated 4-20mA output proportional to the conductivity reading
  • Optional integrated flow switch manifold
  • Wide range of contacting and Hall Effect water meters
  • USB Flashstick Support standard for data logs, event/relay and reset logs, and user configuration file import/export
