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
