- Model AEGIS II - Controller

From

The controller AEGIS II/Cool Control Pro continuously measures and regulates the conductivity and controls the biocide concentration to keep pipework and heat exchangers clean.

Treatment of cooling water in evaporation cooling systems - VDI 2047-compliant

The AEGIS II records all the necessary measuring parameters for cooling water treatment and controls the functions necessary for smooth operation:

  • Measures the electrolytic conductivity – controls bleeding
  • Biocide metering – time-dependent or as measurement and control, VDI 2047-compliant (e.g chlorine)
  • Corrosion measurement – determines whether enough corrosion inhibitor is being metered
  • pH measurement – measures and controls the pH value

  • Control of biocide metering over 1, 7 or 28 days, real-time clock
  • If desired, the biocide concentration can be measured and controlled online
  • Measurement of conductivity, temperature and flow control with the CTFS type digital sensor
  • Serial web interface for unit configuration and remote maintenance with e-mail alarms (the controller must be connected to the Internet for e-mail alarms). WiFi as an option
  • Forced bleeding: performs bleeding before biocide metering, based on time or measured values
  • Bleed lock: blocks bleeding after biocide metering has taken place

Technical Details

  • 8 digital inputs for contact water meter, flow detector and control signals
  • 10 status LEDs display the operating status
  • 9 flexible relay outputs: for setpoint-dependent flow volume-proportional or time-based control of actuators
  • Measured variables: conductivity, pH, ORP, chlorine, bromine, chlorine dioxide and more

Field of application

  • Control of bleeding in evaporation cooling systems
  • Volume-proportional control or regulation of the metering of corrosion inhibitors, de-foamers and dispersants
  • Measurement and control of the inhibitor concentration through the use of a fluorescence sensor
  • Measurement and optionally control of the pH value and ORP voltage
  • Metering of biocides, based on time or measured values
