High-speed spiral door EFA-SST® Classic.

The EFA-SST® Classic high-speed spiral door is an extremely fast, safe and reliable exterior door. The door panel consists of double wall aluminium laths, thermally separated profiles provide (on request) for the best in heat insulation. Any required light entry will be constructed as necessary from multi-clearview laths of acrylglas (SAN). An additional locking device guarantees a very high degree of security against burglary. The widest range of equipment and extensive accessories distinguish the high-speed spiral door as the model for the today’s door technology.

Spiral doors meet all standards: moving parts are carefully clad to ensure the best possible protection against infiltration and efficient finger trap protection. All doors are equipped with a stabilising device for weight compensation as standard: A tension spring mechanism, which automatically pulls the door leaf up if, for example, the emergency hand lever is activated in a power cut, is installed in the side frames. The door is protected at closing level via a contact bar or an optoelectronic system, which is fully integrated into the side frames, and thus protected. The EFA-TLG® produces an infrared light grid measuring a maximum of 2.5 m high installed directly in the door closing line.

EFAFLEX provides high-speed spiral doors of various different designs. The circular spiral is the standard solution, and also boasts the fastest opening/closing times. If you only have limited space above the door, then you have two space-saving variants to choose from for many door types in the S Series. Oval spiral and low header.

High-speed spiral doors are always an intelligent solution. Diverse models are available, whether it’s an entrance and exit door for underground garages, a low-lintel version or if fully ventilated instead of standard laths are to be used in the design. And if colour is an issue, almost all RAL colours are available, e.g. your company colour.

Power is transmitted through strap hinges with protected rollers on both sides. A connection shaft ensures synchronization. All laths are individually screwed to the strap hinge for free movement preventing transmission tension within the door panel Rubber sections link the laths together with a „clip“ technique, making them weatherresistant. This is why individual laths can be quickly and easily.
