- The profiles of the enclosure are established within the frame and are produced in two parts to limit the transmission of temperatures. They consist of a U-shaped PVC profile needed to guide the leaf, in which it slides while maintaining its hermetic and watertight seal.
- The transmission pulley (159 mm diameter) moves within two universal support bearings to allow a perfect balanced movement without tension on the plate.
- The fire door is operated by a powerful motor (three phase / 380 volts). In case of fire, an additional 24 V motor driven by a low voltage emergency device ensures that the door closes properly.
