ProMinent - Model AEGIS II -Controller

Treatment of cooling water in evaporation cooling systems - VDI 2047 and 42-compliant Federal Immission Control Ordinance (BImSchV)-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 and 42-compliant. Federal Immission Control Ordinance (BImSchV)-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

• 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

• 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
