Multi-Wing's Wind Tunnel

One of the key assets that helped establish Multi-Wing as the world leader in axial flow impeller design and production is our wind tunnel, which is based at our research facility in Denmark. Initially installed as a new product development tool, this test facility has played an important role in producing vital empirical data. All the performance data contained in the Multi-Wing impeller selection software (the Multi-Wing Performance Optimiser) originates from this wind tunnel.

The wind tunnel is designed to the AMCA A/ISO 5801 Standard, 12 computer controlled and recorded measurements produce extremely accurate and reliable performance data for an impeller’s entire pressure range. The wind tunnel has enabled Multi-Wing to stay at the forefront of impeller design and to develop a comprehensive range of impellers with blade profiles to meet the demands of the industrial and HVAC markets.

Our customers have also enjoyed the direct benefit of the Multi-Wing wind tunnel by using its data to make improvements to their own applications. This helps qualify the precise airflow and helps test the impact on performance of construction changes to the impeller housing.
