Aluminum Alloy High Speed Fast Rapid Roll up Shutter Door

ΦPRODUCT INTRODUCTION The biggest feature of this series of doors is good thermal insulation and fast running speed, and all of them are equipped with safety gratings as standard. In the process of opening and closing the door, there is no contact and friction between the door panels. It is a quick door with heat preservation, energy saving, sealing, high efficiency, wind resistance and environmental protection. The maximum opening speed can reach 3.7 meters per second, which is suitable for high-speed and frequent logistics channels. The door panel is made of 0.7mm thick double-layer stretched aluminum plate, and the middle insulation material is filled with polyurethane foam. The cross section is designed as a broken bridge thermal insulation structure, which has the characteristics of good thermal insulation, light weight, high strength and impact resistance, and the wind resistance level is ≤12. This door type is suitable for the fast passage of indoor and outdoor logistics and production The adoption of this door type can save energy loss caused by air circulation for enterprises, which is about 80% less than that of ordinary industrial sliding doors and rolling shutter doors. The rapid opening and closing of this door greatly improves the production efficiency of enterprises. This door is the only passage for enterprise logistics and production, and its use and selection are directly related to the efficiency of enterprise production and logistics. Pefo hard quick-opening door has the characteristics of high reliability, practicability, easy operation and quick repair. The drive control adopts a stable, energy-saving and accurate servo system to ensure the reliable operation of the door body, in order to ensure trouble-free operation for more than one million times a year. When the gate is opened, the door panel is safely guided into the top spiral track, and there is no contact and friction between the door panel and the door panel. Standard three-phase frequency conversion control system and The chain drive system with spring compensation makes the maximum opening speed of the gate reach 3.7m/s. The guide load-bearing track of the door ensures low noise when the door runs at high speed, and there is no friction between the door and the track. According to the on-site civil engineering structure, it can be divided into: turbine suction type, elliptical suction type, heavy straight lifting type, 90-degree standard turning lifting type or more track modes. The standard is turbine suction type and elliptical suction type, and other lifting methods need to be designed by appointment with our sales staff. Security system: Infrared safety protection electric eye: there are opposite electric eyes on both sides of the door frame, and there are objects under the quick door to keep the door open; When something passes under the door when it descends, the door will open to the maximum open position, and then it will descend with a delay when there is no obstacle below. Bottom safety protection edge: when the door body is descending, because the object is in the blind zone of infrared safety protection, when the door body presses against the obstacle below, the door body quickly rebounds to the maximum opening, effectively protecting the object below or pedestrians from accidents. Infrared light curtain: This configuration is the most effective safety protection method unique to the industrial door of Pefo. A group of grating walls are installed in the vertical direction, which is usually composed of 18 groups of optical heads. Using 485 communication protocol, the position of the door curtain is calculated according to the real-time height of the door curtain body, and it is a measure to protect pedestrians and objects passing by. Wind resistance: 40 M/S (DIN EN 12424 wind resistance grade 11) Thermal insulation performance: thermal insulation coefficient: K-VALUE 0.4W/M2K. Transparent window: optional Sealing performance: guide rail sealing, door body connection sealing. Quick repair: In case the door body is damaged, the whole door body does not need to be repaired, and the aluminum alloy door panels fixed by suspension can be disassembled one by one, which is simple and time-saving.
