Aluminum Spiral High Speed Doors with high strength and thermal insulation

Both fast running and high strength. It can be used as exteral security doors with heavy traffic and also need to prevent outside people.  It can also be used as thermal insulated rapid doors fit for temperature-controlled rooms.


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.


High frequency working

 

The motor is frequency motor, and control panel is frequency inverter system. It can change work power output gently. So the door can start and stop in a soft process. Its running speed will accelerate or decelerate gradually. This can avoid overriding and over-heating caused by constant up and down. So the door can keep running and no need worry its motor burnt or 

structure damaged. 


Our door can run up to 2000 times per day. This is why it is a best choice for busy area with 

heavy traffic like forklifts or passing workers. Our door can run up to 2000 times per day. This is why it is a best choice for busy area with heavy traffic like forklifts or passing workers.
