Veolia Control Units


  • RO6 is a simple programmable electronic controller with alphanumeric digital display for conductivity in μS/cm, temperature, display of the current state of operation, clear text display in the case of a fault. It is very simple to use.
  • RO30 is a flexible controller which provides the control and switching on and off of the pump, valves etc. It continuously monitors the input limit values, giving a fault signal in the case of an out of specification value, stopping the plant with a time delay if appropriate.
