Find the right window drive with GEZE

Depending on the installation location, modern construction methods may require automated windows. Often, the window elements needed in these applications are simply too large and heavy to operate manually. In daily operation - integrated into the building automation system - they provide natural ventilation and ensure the indoor climate is fresh and comfortable. In case of fire, the window drives manage air intake and outflow for natural smoke and heat extraction.

Automatic window drives for many different applications

Automatic window drives are essential today in many public buildings such as large office buildings, shopping centres or hospitals. They provide natural ventilation, and timed window controls ensure, for instance, that they cannot be left open overnight accidentally. Remote-controlled operation also offers advantages in terms of hygiene, because window handles do not have to be touched. The supply of fresh air improves indoor air hygiene and reduces the risk of viral infection.

Fire escape routes, thanks to natural smoke and heat extraction

Last but not least, opening drives on windows play an important role in smoke and heat extraction: In the event of a fire, our window drives guarantee that the escape and rescue routes remain as smoke-free and accessible as possible. Smoke and heat extraction opening and locking systems consist of a spindle drive and a mechanical fitting set. When smoke and heat are present, intelligent smoke extraction solutions open the windows. Even a small spindle stroke can open the window wide in just seconds. The heat and smoke generated by a fire accumulate below the ceiling and are then discharged through the air intake or exhaust air system.

Using window drives for natural ventilation

More and more building owners are discovering the benefits of automatic window openers. These are becoming popular for use them in modern office and residential buildings to increase comfort. The window drives provide a daily supply of fresh air, while helping to improve energy efficiency: If they are centrally controlled, they prevent uncontrolled opening of the windows at low temperatures. The advantages of automatic window drives are extensive - just like our range of products.
