Axial Fans

The airflow is created by highly efficient axial fans, each 3.5 metres in diameter, manufactured by EVG ( – one of the leading manufacturers of industrial ventilation systems. The heart of the axial fan is the 400-450 kilowatt electric motor made by Siemens.

Each axial fan is supplied with:

  • an individual frequency convertor
  • carbon-fibre blades (lighter and more reliable than aluminium blades)
  • vibration dampers
  • a set of sensors and diagnostics controllers: vibration, temperature, oil, dynamic and static pressure (pitot tubes)

The axial fans are installed during construction work by EVG engineers. Installation usually takes approximately two weeks.
