High-speed spiral door with low lintel EFA-SST® N Premium.

With the EFA-SST® N Premium, we present a technological innovation that has never been seen before. Thanks to the specially developed and patented guidance technology, the so-called polygon effect can be reliably prevented. This means: no vibrations, no jerking – even at top speeds. We provide not just one, but two guide lines in the transition section of our guides. Our low lintel door therefore sets completely new standards in terms of speed, smooth running and space saving. It combines state-of-the-art engineering with practical suitability for everyday use – for applications where previous solutions have reached their limits.

With the new patented door leaf guide, we have set a milestone that will forever push the boundaries of what an industrial door can achieve. It’s not just a door; it’s a strategic tool that speeds up your processes, reduces your costs and improves your working environment. It’s the future of access – with you today.

In addition to impressive opening speeds of up to 2.0 m/s, the low-lintel door impresses with exceptionally quiet and low-vibration running behavior – even with large doors. The precise mechanics ensure minimal friction and low wear – making the door not only quiet, but also particularly low-maintenance and reliable in continuous operation.

Thanks to its compact design and minimal lintel requirement, the EFA-SST® N Premium is also ideal for use in confined spaces. The space-saving design opens up new possibilities in areas where conventional sectional doors reach their structural limits. Whether as a high-speed industrial door, to separate production areas or in other demanding installation situations – our solution is versatile.Thanks to its compact design and minimal lintel requirement, the EFA-SST® N Premium is also ideal for use in confined spaces.

EFAFLEX is the world’s first manufacturer of industrial doors to offer thermally separated EFA-THERM® insulating slats as standard. As a result, the door achieves a very good U-value of up to 1.6 W/m²K and thus minimizes heat and cold losses – particularly important for temperature-controlled zones, logistics centers or production areas with a high level of environmental awareness.

The EFA-SST® N Premium also sets new standards in terms of security. It meets the requirements of Resistance Class 2 (resistance class) in accordance with DIN/TS 18194:2020 and is equipped with intelligent spring breakage detection. Other security features ensure that people, machines and goods are optimally protected at all times – reliably, tested and state-of-the-art.

Less jolting, fewer vibrations means drastically reduced wear. The loads on the door blade and structural parts are minimized, resulting in a considerably longer lifetime for your entire door system. Less maintenance, fewer repairs – more operational reliability and lower operating costs for years to come.
