The EFA-SST® TK-100 high-speed spiral door is the first true single-door solution for freezer areas. In addition to the highest opening and closing speeds, it achieves the best insulation values for spiral doors and thus represents a high-quality solution for every deep-freeze room.
In order to withstand frost, the EFA-SST® TK-100 is equipped with contact surface heaters that are integrated in the surrounding sealing profiles and in the contact strip profile. These heat the contact surfaces of the seals against the door leaf and the floor. As a result, an EFAFLEX deep-freeze high-speed door saves its users up to 50 percent in the heating costs compared to other door solutions. The result of this unique design are U-values as low as 0.62 W/m²K and operating temperatures between plus 30 °C and minus 30 °C.
The EFA-SST® TK-100 impresses with its innovative door design: the door has a circumferential profile seal and a dynamic door leaf guide, which is mounted on the cases and the spiral support so that it can be moved. As a result, the active guide rail mechanism (EFA-AFM®) moves the door leaf towards the door case when the door is closed and, in combination with the profile seal, closes the door almost hermetically. Compared to other door designs, the installation level for doors of the EFA-SST® TK-100 series is always on the outer, i.e. the warm side, in order to be protected from cold-related wear and tear. The 100 millimetre thick, thermally separated EFA-THERM® insulation laths used as standard in the EFA-SST® TK-100 guarantee even better thermal insulation than ever before.
As the world’s leading manufacturer of high-speed doors, it is our aspiration to also be pioneers in the field of safety: All EFAFLEX products meet the highest standards and protect both people and the goods as well as the door itself.
It is not only our industrial doors that impress with their state-of-the-art safety technology, but also the associated systems: EFA-SCAN®, for example, is the world’s first laser scanner for use on doors, which is a reliable pulse generator and safety system in one.
