RRD-ZIP Zipper type High Speed Doors with high air tightness and self repairing function. It is quite fit for high standard food and drug factory, clean room, laboratory and dust-free workshop, where there is extreme high demand of hygienic and clean indoor environment. And also it can minimize long-term maintenance and repair cost for areas with heavy forklift traffic . Rapid Roller Door is a type of automatic roll up door that is designed to open and close very quickly, widely used in modern factories and warehouses. It can run in high speed and frequency, very fit for areas with heavy traffic. It improves efficiency of material handling. On the other hand, air flow and heat conduction through the door is reduced obviously, to keep clean, hygiene and temperature inside room. Automatic running is realized with programmed control system and sensors. High speed running The opening speed can reaches up to 2.0m/s. And the closing speed can reaches up to 1.0m/s. This means that the door can finish a cycle of opening and closing within in several seconds. It bring several major benefits: Improve work efficiency: Workers or forklifts will no need wait in front of the door and can directly go across it. The material handling speed is higher by at least 5 times than tradional roll up doors; Keep clean and hygiene: The fast running reduces the open time to only seconds in a cycle of passing the door. Thus much less outside air and dust will enter the room; Keep temperature: Heat loss is reduced by large by reducing open time.
