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.


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

   Self-repairing after collision accidents


Bottom beam of the door curtain is flexible soft design, quite different from hard metal beam of regular rapid doors. When there is a collision accident by forklift or other vehicles, it will 

get out from side frame and not be damaged. Then the curtain will automatically enter the 

side rail through a pull-back device at the top of the rail.And it can recover automatically. 

This design effectively reduces the cost and energy of maintenance and repair work caused by collisions. 


High air-tightness


Special zipper design structure at two sides of door curtain, connecting the fabric and side 

guide rails as a whole body, eliminating gap between them. It obviously improves overall 

seal performance and air tightness.  


Thus, such doors are quite for high-clean areas, like clean room, food or pharmaceutical 

workshop, or laboratory. It will help prevent outside air and dust entering the room. 

Benefiting from its zipper airlock structure, it can keep the air pressure difference inside air controlled clean rooms, air shower or laboratory. 

  

   Longer work life with lower maintenance

     

    Advanced Italy servo technology drive motor and control system. Compared with 

    traditional door system in the market, it has several advantages:

 

  • Double encoders:  They calibrate with each other, to make running limit

    more accurate than tradtional limit sensors. This completely avoid running

    limits error and reduce maintenance. And even if one encoder is damaged, you can

    switch to another encoder and the door will continue to work well, no need repair;


  • Absolute encoder: outside encoder is advanced absolute encoder. It will always keep the set limits even during power failure. So you no need bother to do the frequent job

    of re-seting the limits;


  • Flexile Torque Control System:  The output torque of motor keeps changing  

    according to running speed and load automaticlaly. This avoid over-heating and

    over-load after long time use, and make sure the door work longer life.


User freindly Human-machine interface system


There is a LED display on the controller, showing all parameters and setting steps in 

English language. You can set or change any parameters like using a mobile phone. So you will feel very easy and comfortable to use the doors even you do not have any experience. 


And it is inbuilt with Fault-shooting program. The display will show the error information

when there is some problem. 


There are addtional input and output signals in the controller. You can activate it by the 

screen and the door will work together with your production line, robots, conveyor, or other machines.

 

   Various Colors 


  •   We supply six different colors for your choice. You can make a free selection 

       among them. Our doors can integrate into your whole building design and 

       make the building harmony and beautiful.

       Blue, Yellow, Orange, Grey, White, Full clear


  •   A transparent window can be made at human eye height. This makes it easy to

       see what is happening at another side of the door. It will be more safe for a 

       busy area with moving workers and forklifts or other vehicles. 


Multiple safety protection


Considering the high speed running of the door, safety protection become very 

important to avoid possible accidents.  This can not be neglected when using 

such high performance doors. 

There are three safety protection devices:


  • Safety photo sensor:  The sensor can send a infrared light beam from one side 

     to another. When it is blocked by passing human or vehicles, the door will 

     immediately stop or get up. Thus it aims to avoid accident;


  • Safety airbag sensor: It is a soft rubber airbag at the bottom. If something 

      touches the bottom, the door will stop or get up. So it aims to stop accident

      once it happens;


  • Alarm lamp: It gives out light flash signal or sound signal when the door 

     running. Passing workers or vehicles can easily get aware that the door is

     working and take special care to avoid accidents.


   Interlocking Function


    In some industries like food, pharmaceutical or electronics, it is a very 

    important issue to keep hygiene and clean inside the room.  This is critical 

    to keep final quality level of the finished products, no matter it is food, 

    medicine or electronic applicances.  How to prevent outside air and dust is

    a major difficulty. An interlocking passage system can solve this problem 

    perfect.  


    Door A and Door B are installed at two ends of the passage. When door A 

    opens, Door B will never open. Only after Door A closed, Door B can open.

    Thus, at any time, there is at least one door keep closed. So the outside air 

    and dust will never be able to enter the room.

 

     We have input the interlocking function in every door.  When necessary, any 

     two doors can be interlocked. 




Various Operation Methods


Every door will have wall mounted control buttons at both interior and exterior. This can make sure the door can be operated by workers at any time when they need. 

To improve your work efficiency, we also offer various addtional choices of operation devices.


  • Remote control:  Each door can have two or more remote control units. People can open or close the door from as far as 100m distance; 


  • Radar sensor: It can detect human or vehicles moving towards the door, and the door will open automatically. After passing through, the door will close automatically within several seconds which can set;


  • Vechicle loop detector: It detecting wire loop will be embedded into ground floor near the door. It can detect all the big metal objects passing on its loop like forklifts.  It does not detect humans. Thus such sensor is quite fit for doors which only allow forklifts passing automatically. 


  • Pull-cord switch:  This is very convinient for forklift drivers, and also can avoid unnecessary opening of the doors compared with radar sensors or vehicle detector;
