Deutsche WindGuard Engineering GmbH

In today’s complex energy market, Deutsche WindGuard is committed to providing extensive scientific, technical, and operational services, which are unbiased and manufacturer-independent. Our core areas of expertise are Measurements, Technical Inspections & Management, Offshore, Site Assessment, Consulting, Certification and our Wind Tunnel Centre.

Our acoustically optimized large-scale wind tunnel is operated by Deutsche WindGuard Engineering and located in Bremerhaven. Since the start of operation in 2008, the test section was continuously improved and offers one of the most advanced wind tunnel testing facilities in Europe. With its specific design and redundant measurement system, the wind tunnel is particularly optimized for aero-acoustic research & development projects. It also allows for testing on comparatively large components and realistic models. Calibration and function tests of wind measurement sensors at high flow velocities are also possible, just as the use for R&D projects for the industry as well as for scientific institutions.
