Closed circuit Wind Tunnels (WT) are a fundamental tool for specialized research and development in aerodynamics and fluid mechanics. Thanks to their closed loop design, they allow for high control of airflow conditions, minimizing pressure and kinetic energy losses. This enables high precision achievement and reproducibility of test results.

The higher investment is balanced by more precise results and lower operating costs, as they do not require as much power as open circuit tunnels. Additionally, they allow the Test section to be configured as both closed and open.

Closed WTs are the ideal choice for companies and research institutions requiring a high level of experiment control and result accuracy. They are suitable wherever it is necessary to minimize external influences and ensure consistent test conditions.

WTtech.CZ will design, manufacture, and deliver WTs tailored to your requirements: from the size of the test section to the quality and speed of airflow, to the integration of sensors and data output interfaces. And this is implemented considering the laboratory dimensions and power input possibilities. Thus, you will get an exact tool customized to your conditions.
