Test Facility Description

 Wind Tunnel Centre

Accredited calibrations

Our position as a recognised expert in all matters relating to wind energy is reinforced with our own research and measuring equipment. Four calibration wind tunnels and two special tunnels (ice and pressure) form the Wind Tunnel Centre at our headquarters in Varel. The calibrations are recognised by the independent institutions Deutsche Akkreditierungsstelle GmbH (DAkkS) and MEASNET. Since 2009 one of the calibration wind tunnels has been used by the Physikalisch-Technische Bundesanstalt (PTB) to define the unit “metres per second” in the area of flow measurements and is therefore the national standard for this physical unit in Germany.


Large wind tunnel in Bremerhaven

In addition, our acoustically-optimised large wind tunnel in Bremerhaven has been operational since 2008. The tunnel offers high wind speeds at low levels of turbulence, together with the most advanced drive and control techniques for ideal conditions for research and development. The aerodynamic and acoustic optimisation of rotor blades benefits from the data obtained in our wind tunnel, as do the marine and automotive industries.
