Cool-Control Cooling Tower Controller

Cool-Control Cooling Tower Controller

The cooling tower controller DULCOMETER® Cool-Control is a measuring and control device based on microprocessor technology offering the highest degree of processing reliability in a broad spectrum of applications. The controller is configurable and so can be individually adapted to your requirements. You choose and pay for what only you need.

Advantages

  • Optimum adaptation to processing requirements through different levels of configuration
  • Seamless integration into your processing technology: Variable installation options for sensors and different control options for dosing equipment together with blowdown shutter valves and valves.
  • Safety: Threshold value monitoring and adjustable maximum duration of blowdown
  • Simple and easy-to-view user guide in full text via a large graphic display in many languages
  • Large, easy-to-read graphics display for measured values, correcting values and information.

Areas of application

  • Cooling tower
  • Air washers
  • Air humidifiers in climatic engineering

Features

  • Blowdown control
  • Dosing of a corrosion inhibiting agent
  • Dosing of 1 or 2 biocides
  • Daily and 2-weekly timer
  • Forced blowdown and blowdown shutoff
  • Calibration function for the dosing pumps
  • Water meter input with adjustable pulse spacing
  • Pause input for blowdown shutoff
  • Signal output for temperature-compensated conductivity, 0/4 – 20 mA, galvanically separated
  • Alarm relay for alarm output
  • Adjustable alarm threshold for the measured value of conductivity
  • Wall and panel mount housing
  • Adjustable access code

ProMinent besides offering DULCOMETER measurement devices and controllers also offers DULCOTEST fluid conduction sensors and dosing pumps to build a complete closed loop. Measurement, control, dosage and recording, all from one source and optimised to work together.
