SST High-Speed Spiral Door - 2nd Generation

Insulated and Acoustically Rated

EFAFLEX has completely redefined the approved concept with its new high-speed spiral doors series SST. The three designs PREMIUM, ECO and BASIC provide three user-friendly types according to service requirements. The innovation: The new SST is the first high-speed industrial door in the world with an insulated door panel and laths up to a size of 100 mm. Thus, the SST is a purpose-made, quick, safe, and heat-insulating hall door.

The SST can also be used for the application of logistic systems with the highest demands, for example, in production companies, parking garages, underground car parks, car washing plants, shopping centres, etc.

The new technical concept displays an improvement in the physical characteristics of the door leaves as well as an optimisation of functionality.

Revolutionary and advanced: the new EFA-THERM® laths

We are the world’s first manufacturer to provide a series of thermally insulated EFA-THERM® insulation laths for EFA-SST®. These achieve outstanding heat insulation between 0.66 and 1.52 W/m²K depending on door size. The latest door blade is extraordinarily robust, long-lasting, tight and sound-insulating. Depending on how much light you wish to allow in, we can incorporate as many EFA-CLEAR transparent acrylic glass laths as you like into the blade of your EFA-SST®. These are also available in double-wall design.

World innovation: EFA-SST® with self-repairing door blade

As the leading specialist manufacturer of high speed doors worldwide, EFAFLEX offers a combination between a rigid door blade and active crash system. Customers can specify this unique mechanical and electronic safety system for the Premium model of the EFA-SST®. EFA-ACS not only protects the door against damage and therefore downtimes and repairs – the EFA-ACS fully automatically repairs the door in just a few seconds! Should there ever be a collision, your door will still be serviceable again immediately.

How the world innovation works

In the event of a collision, the detachably connected laths are pushed out of their guide rails, undamaged. An inductive sensor system records this and, while slowly retracting the door upwards, safely and properly restores the door blade and frame to their proper condition.

Powerful core

We always deliver the EFA-ACS in conjunction with direct synchronous drive (DC), where the load is applied directly to the topmost door blade lath. That eliminates wearing power transmission elements such as motor drive belts and pulleys. This compact, low-maintenance construction guarantees an even longer service life, quiet and precise running, and dependable EFA-ACS triggering every time.

Top in all respects

The new EFA-SST® generation fulfils highest expectations even under heaviest continuous operation. The EFA-SST® is extremely stable and weatherproof. It boasts outstanding heat and noise insulation, and surpassing wind resistance. The new high-speed spiral doors “undyingly” withstand up to 250,000 load cycles per year with minimal maintenance requirements. You can expect a long service life from the EFA-SST®!

Special models

EFAFLEX offers the EFA-SST® in a model that fulfils all standards for explosion-protected rooms. All electrical components are certified according to the applicable EU directives. The mechanical protection consists of brushes for electrostatically discharging the door blade, full grounding of the door installation and non-isolated installation of all metallic parts. In cooperation with the automotive industry, we have also developed a special model that complies with all regulations regarding laser beam strike.

EFA-SST®: unbeatable in materials handling

In automated logistics, doors are often under very heavy goods traffic. This is where the advantages of EFA-SST® come in most clearly. Our High-Speed Spiral Doors ensure extreme speed for rapid material flow, and can withstand extraordinary numbers of load cycles. The EFA-SST® can be connected over interfaces to a controlling computer.

In materials handling, a high-quality High-Speed Spiral Doors such as the EFA-SST® offers yet further advantages: in particular, unrivalled heat insulation pays off when storing fresh goods, for example. The EFA-SST® also seals tightly against dust. High- Speed Spiral Doors also make an important contribution to the safety of the conveyed goods.
