The Slimchain and Powerchain chain drives can be flexibly used. The Slimchain is the slim all-rounder. For instance, it can be used very easily for automating parallel-opening vent windows, supporting an efficient exchange of air with a facade view which is always consistent. The Powerchain is the power package for large and heavy facade windows, roof windows and light domes. The drives differentiate between alarm (RWA) and ventilation mode, i.e. a fast and maximum or a slow, limited and virtually noiseless opening. The adjustable drive stroke and the opening speed which can be individually adapted enable use on RWA and ventilation windows of various closing forces and with different opening requirements. If an 'RWA event' occurs, the drives can attain very large opening widths in under 60 seconds.
The integrated, intelligent control allows drives to be combined easily. The control unit ensures the sequential and safe opening and closing of the windows, as well as the synchronisation of up to three drives.
