Bespoke solutions for wind tunnels projects

Wind TunnelsWind Tunnels


Backed by over 50 years’ experience in designing and manufacturing high efficiency axial fans, Zitrón offers bespoke aerodynamic solutions for all types of wind tunnels worldwide.

Fans are the primary component of wind tunnels, providing a concentrated stream of air in either a vertical or horizontal flow. Their design is therefore of critical importance in guaranteeing the success of any wind tunnel, be it used for recreational or industrial purposes.

This is an area where Zitrón excels, through the use of 3D CFD simulations to optimise air-flow circulation, the application of know-how gained over many years and the ability to conduct comprehensive fan testing in our in-house test bench facility.

Zitrón’s experienced and highly qualified engineers can provide a complete package for your wind tunnel requirements, covering all elements from design to manufacture, and installation to maintenance.
