An  example of how important Fieger Louvre Windows are for industrial buildings can be seen at "Industrial-park Hoechst".

The production plant of "Technion" with its test facilities for chemical products needed superior demands on the ventilation system throughout its plant. Specially the actuators were important as the windows were fitted in an "explosive area" in the building where any electricity could be fatal.

Therefore only pneumatic cylinders have been used. A compressor provides pressure to open and close the windows for natural ventilation and a superior CO2 cartridge enables the louvre windows to open in case of a fire to release smoke and toxic gases. Fieger Louvre windows combine both, the security and the natural ventilation of fresh air, in one system.
