Our fastest door
Thanks to its spiral technology, the EFA-STR opens with an incredible speed of more than 4 m/s. With the EFA-STR, your logistic processes become faster and more efficient. Our fastest door – a combination of the spiral-shaped door guidance and the flexible door blade guarantees you an optimal traffic flow!
High load capacity and extreme stability
The EFA-STR does not only move with an incredible speed but also requires extremely low maintenance, is heavy-duty and extremely stable. The flexible door leaf is led laterally and is moved upwards and downwards in a force-closed manner: Linear expansions are ruled out. It consists of individually replaceable, 4-field module segments. Aluminium profiles reinforce the curtain with a distance of 225 mm.
Self-repairing door leaf: Active Crash System EFA-ACS
Especially with regard to extremely high speed, safety is a big issue. Best protection is offered by the Active Crash System, by means of which the door leaf repairs itself. EFA-ACS®, the completely new crash protection provides a fully-automatic, electronically monitored retraction of the door leaf after a crash.
This is how the Active Crash System works
In case of a collision, the demountably connected laths can be pressed out of the guide without being damaged. This is recognised by an inductive sensor system which joins the inner and the outer hinges of the door leaf again in a safe and correct manner during a slower upwards movement.
Door leaf guidance in perfection
Copied a thousand times - but still unequalled. The door leaf is not wound-up on a shaft but kept space-saving in a certain distance in the patented EFAFLEX spiral. This functional principle guarantees quite a number of unique advantages: only this unique design combines highest opening speed, long service life and efficiency in such a perfect manner. Thanks to the spiral, the doors move quietly and wear-free - and look as good as new for many years.
