The Cooling Tower Control System (CTCS) is an integrated system that control a cooling tower's acid feed, blowdown and inhibitor/biocide feed.

Acid feed is controlled via pH, blow down is controlled via Conductivity (TDS) and inhibitor is fed on a user selectable timed basis. Both the period and dose time are easily configured by the user.

Cooling Tower Control System features a timer based overfeed function that locks out the blowdown cycle or acid/base feed function and triggers an alarm if the acid feed or blowdown cycle proceed longer than the predetermined time.

The Lockout Timer Alarm is reset with a simple push button switch that resets all 1mers allowing a second interval to pass. If the control parameter is corrected the relays will return to the normal state. If not then the 1mer will ini1ate another alarm.

The standard outputs include two isolated 4-20mA outputs, one for the pH signal, one for the conductivity signal and four SPDT 230 VAC 5A relays, (1) acid/base feed, (2) blowdown control, (3) biocide feed and (4) system alarm.

FEATURES :

  * Dual input design, pH and conductivity sensors
  * Control logic and failsafe interlocks
  * Biocide feed Timer
  * Configurable control outputs
