Roll Screen Systems
Roll Screen Systems: HS double duo 100mm
The newly developed Novavert tube “HS double duo” with an outer diameter of 100mm sets new standards for roll screens. Previous roll screens with an outer diameter of 50 and 63mm required that the tubular motor had to be flanged onto the roll-up tube – thus the cord had to be cut off. The fastening on the coupling tube is normally done with a double-sided adhesive tape. But this is the worst possible solution for the installation as well as for the exchange, as it make cause uneven rolling-up and folds in the roll screen. Sensitive materials may be damaged.
Smooth and uniform winding
With HS double duo 100mm the roll-up tube comes close to the guide carriage. The secret is the inner diameter of 63 mm, which now allows to flush mount tubular motors into the tubes. No cord needs to be cut and a possible exchange of the drive is a matter of a few minutes.
Less danger of overheating
Previously the motor was wrapped in the rolling screen material and could overheat quickly. But now there are four large air gaps where the heat can escape or it is carried off via ribes, respectively.
Due to the larger diameter partition walls can be rolled up essentially faster.
The significantly higher flexural strength has an positive influence on outdoor walls because they require less vertical posts as wind protection. For extreme conditions we suggest a wall thickness of 7 mm: With adequate flanges and bearings it can be used for very wide doors and is also suitable for roll screens under high wind load.
Less torsion and higher transmitted torques allow particularly long roll screens with flanged, external electric winches. In this connection, attention must be paid to an appropriate counterweight.
