The EFA-STR High-Speed Roll-Up Turbo Door opens a new dimension in door construction: with opening speeds of over 3.6 m/sec the EFA-STR is the worldwide fastest door system of its type.
NEW: The Active Crash System EFA-ACS with its electronically monitored, fully automatic return system represents an accessory for EFA-STR doors which is highly recommended:
For the first time flexible and differing coloured door panels have been combined with the spiral formed door panel accommodation. The individual curtain components accommodated in the patented spiral are held away from each other, so that a contactless and practically wear free travel is guaranteed. Even sight sections remain fully transparent for many years. Further the door panel is made of individual, rapid and simply replaced segment-modules. Excellent wind stability, secure sealing and smooth travel also provide for exceptional availability.
NEW: STR Active Crash System ACS with direct-synchronous-drive
The innovative direct-synchronous-drive (DS)gives a virtually wear-free drive with smoothest running. The drive is now attached directly "to the top of the door blade" by a drive shaft and synchronously arranged telescopic extension arms connecting on the top lath of the door blade. This reduces the wear on power transmission parts considerably. At the same time we could substantially improve the safety level for uncontrolled descent of doors. Furthermore we achieved a considerably longer operating life of important components, because amongst others the blue belt has been replaced by a flyer chain and in particular the stress of the springs could be reduced, too.
