EFA-SST® at a glance
The new generation
Worldwide increasing energy prices have prompted EFAFLEX to design completely new high-speed spiral doors as hall closure. The technically new design constitutes an improvement of the physical characteristics of the door leaf as well as an optimisation of the functionality.
Trend-setting: EFA-THERM® laths
As the first manufacturer worldwide, we will from now offer thermally separated EFA-THERM® insulation laths for the EFA-SST® as a standard. Thus, depending on the size of the door, an excellent heat insulation of between 0.66 and 1.52 W/m2K can be achieved. The new door leaf is exceptionally robust, long-lived, tight and sound insulating. Depending on the desired light entry, we include as many EFA-CLEAR® transparent laths of acrylic glass into the door as you wish.
Highest profitability – due to best quality
Today, energy as one of the most important factors with regard to profitability is more important than ever before. We at EFAFLEX react to increasing prices and an uncertain raw materials supply: due to the fast opening and closing speed of our doors, only few energy gets lost towards outside or between two rooms. By using EFAFLEX high-speed doors, you can efficiently reduce your energy costs.
With EFA-SST® you save massively on energy costs
We are the world’s first manufacturer to provide a series of thermally insulated EFA-THERM® insulation laths for EFA-SST®. The thermally insulated EFA-THERM® laths of the EFA-SST® considerably improve the thermal insulation, thus lowering your energy costs.
Individual design possible
In addition to the aluminium-coloured standard coating, we also paint the laths as well as the steel parts of the door in almost every colour of the RAL system, if requested by our customers. Thus, our high speed doors can architecturally be perfectly adjusted to every facade or get the colour of your house which gives your premises a representative look.
Fast and safe: EFA-ACS®
As the only manufacturer of high-speed doors worldwide, EFAFLEX offers a combination of fixed door leaf and an active crash system. EFA-ACS® does not only protect the door against being damaged and therefore against operating failure and repairs – it carries out the “self-repair” fully automatically within just a few seconds! In the case of a crash, your door will henceforth nevertheless be immediately ready for use again.
This is how the Active Crash System works
In the case of a collision, the detachably connected laths are pressed out of the guidance 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.
Oval spiral and low header
EFAFLEX offers you high-speed spiral doors in different versions. The circular round spiral is the standard and at the same time the solution of highest opening and closing speed. If there is only few space above the door, you can also chose between two space-saving variants of the many door types of the S series: oval spiral and low header.
With absolute safety
EFAFLEX high-speed doors also guarantee you the highest standard with regard to safety. As leading manufacturer of high-speed doors, EFAFLEX is aware of its responsibility! Therefore, we also want to be pioneers in the field of safety. Our systems bring you much more safety – for persons as well as for the material loaded and for the door itself.
Unique systems – for more safety
Not only the doors itself satisfy the highest demands at EFAFLEX. The appertaining safety systems also offer unique advantages. EFA-SCAN®, the latest EFAFLEX patent, is the first laser scanner worldwide which can be used in a door on the one hand, and which is an activator as well as safety system in one and the same product on the other hand.
