KA series: the flexible device that does it all
The versatile all-round talent
A multitude of designs make it possible to use the KA Series chain drive for all common window types. As a true all-rounder, it provides a custom fit to meet your requirements and features a variable length dimension as well as the option to adjust force and stroke individually. The BSY+ synchronised electronics can be used to control multiple drives at the same time upon request. So much variety in only one drive—nothing can match this speed! A force of pressure and tensile force up to 600 N and a stroke length up to 1300 mm allows this window drive to control the movement of almost any façade window, roof window or skylight with ease.

The Arena Lublin stadium in Poland holds more than 15,000 sports fans. The numerous bottom-hung windows in the luxury boxes and in the facilities inside the stadium are driven by the versatile chain drives of the KA Series.

Some 32 installed chain drives provide a smart SHEV solution in coordination with controllers and lock drives. In case of fire, the windows are opened automatically, and the toxic gases can escape.
