STT-speed roll-up door is unique in the world of high-speed doors for indoor use, the technology is a world leading level. Curtain composed of a single layer of slats, is almost completely transparent, lath PVC-free material by molding, it is applied to the chemical, pharmaceutical, automotive (paint shop) as well as all areas of food processing. STT-speed roll-up door, whether in high or low pressure can maintain a good seal, and can withstand more than 120KM / H strong winds hit. Door opening speed varies with its size varies, up to 3M / S. Each batten strips are screwed on both sides of the curtain, so to ensure that even under the curtain hanging in the state, the slats are not subject to the force can be generated by vertical lifting movement of the door roll steel structure, when the door When opened, with the rotation of the spindle, the curtain was involved in the plot was a close orbit, (this orbital patented product, see below), non-invasive touch no wear, use many years later, still remain curtain deformation. If you need to you can easily replace the slats, while strong winds in the function of the door will not be affected in any way. STT is a high-speed roll-up door in the industrial sector in the field of innovative technology products. This door is not only resistant to strong winds, and a high degree of sealing, reliability and availability. Transparent door bar by PVC-free polypropylene glass, can also be installed if desired gray transparent slab. Equipped with high-speed microprocessor and inverter drives, you can make quick start after door soft-start, and finally a slow stop. When the door switch gently, without noise, the design requires the use of at least 150,000 times a year. If in case of power failure, you can also open the door manually operated spring mechanism. Germany EFAFLEX high-speed shutter doors transparent acrylic sheets contain PVC, used for special occasions so that the door fitness, spiral receive product structure has patented the use of the door to ensure that the number of years still transparent as new, unique safety system TLG largely avoided the door crashed possible. Product Features:? Light and speed! ? By using the crystal-clear plexiglass, EFA-STT transparency of the door up to 70%, which makes the EFA-STT become the world's only high-speed roll-up door:? Not only durable, but almost completely transparent. ? Clear vision! EFA-STT? Door bar spacing maintained spiral guides. By way of non-contact wound, transparent door strip almost no wear, and perennial maintain transparency. Thus, the entire door even in frequent daily use there is still bright as new. ? You can trust the quality of EFA-STT? Can withstand up to 150,000 times switch tolerance, which means that within a maintenance cycle can withstand up to 15 million times on and off, showing that the performance is excellent. Case due to rugged, EFAFLEX high-speed roll-up door, even in winds of up to 120 km / h, and still completely normal function, which called the first-class quality in the industry, so EFA-STT?
