The powerful frequency converter control enables opening speeds of up to 3 m/s. Here, the sections are securely rolled up in the spiral bracket without any contact. The rolling shutter is particularly stable, as the sections are connected across the entire width. This enables door widths of up to 6.5 m. Low-noise travel and the long shutter service life are due to plastic hinge connections with a service-friendly clip technology. The shutter has a high thermal insulation value thanks to its sections with thermal breaks.
