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.
TO OUR WINDOW DRIVESFinding the right window drive with three questions
When considering the right window drive for your needs, you should start by considering important criteria. We have assembled the following three questions to help you do just that.
What purpose should your window drive fulfil?
It is important to distinguish whether your drive is only intended for use to provide natural ventilation, or if it is also intended as smoke and heat extraction or as a SHEV device.
All GEZE window drives are suited for natural or automated ventilation. In addition, some models with chain or electric spindle drives can also be used as smoke and heat extraction systems. Our product range also includes narrow slimchain drives (Slimchain) and solutions for especially large and heavy windows (Powerchain). Are you planning to install the window opener in a private home? Then you can use the ECchain chain drive, which has been designed especially for this purpose.
The F 1200+ makes ventilation of even large and heavy bottom-hung and turn-and-tilt windows easy.
There are also window opening and locking systems for providing ventilation only: You can choose from one of our OL varieties.
If you need smoke and heat extraction in addition to the ventilation function, you can choose one of our various smoke and heat extraction variants.
Façade or roof? Depending on the location, you can choose from a variety of window drives.
Each type of opening drive, such as our chain and electric spindle drives, offer various models for different installation situations. Only our electric linear and scissor drives are used exclusively in façade applications. Safety scissor stays prevent leaves from falling, which is why they are mandatory for bottom-hung windows.
In which direction do the window leaves open?
Does your window open outwardly or inwardly?
Smoke and heat extraction and OL variants differ in the opening direction of the window and in the mounting position: RWA 100 and RWA 105 as well as OL 350 and OL 370 are inward opening and RWA 110 and OL 360 are outward opening systems.
Chain drives can be used with both opening directions. With the exception of the E 1500 S and E 3000, spindle drives can also be used with both opening directions as well.
It goes without saying that you want your window drive to fit into the installation situation as inconspicuously as possible. That is why all of our automatic window openers are designed to be very compact. However, as the models are used in different functions, their dimensions naturally differ. Please see the product sheets for further details.
