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
