Controller AEGIS II

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.

Your benefits

  • Timer-controlled biocide dosing.
  • Optional online measurement and control of the biocide concentration.
  • Built in web interface for device configuration and remote maintenance. Optional WLAN/WiFi access point.
  • Bleed lockout: blocks bleeding after biocide metering has taken place.
  • Pre-bleed: performs bleeding before biocide metering.
  • Operating status displayed by 10 status LEDs.

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
  • pH measurement and optional pH control.
  • Metering of up to 2 biocides based on time or measured values.

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.
