It is fast running, thermal insulated, and anti-freezing. Compared with traditonal cold room sliding door, it can help clients improve goods transfering efficiency and also reduce a lot electricity energy cost. Thus you can consider adding such doors as a daily traffic working door which will keep opening and closing during daytime.
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:
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

Insulated insulated sandwich curtain. Total Thickness:30mm. Inside is special cold-bridge design structure. There is separate compartment inside the door curtain to
cut the route of heat transfering. This can reduce heat-conduction by additional
Anti-freezing and ice-proof
Near door area of a cold room, the moisture will quickly form into dew and freeze into ice
because of big temperature difference. The door will not be able to move up and down
smoothly. This bring big harms to its drive motor. So it becomes very critical for the doors to avoid icing and freezing. This is essential to guarantee long work life of the doors.
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.
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:
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
screeen and the door will work together with your production line, robots, conveyor, or other machines.
High IP class of electric parts
The humidity level inside cold room is extremely high, especially near the doors. Moisture will continue entering the electric parts through its unsealed gap. This may bring big
harm to electric parts and shorten its work life. To solve this problem, we select and
adopt electric parts with high Ingress Protection (IP) class.
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:
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;
touches the bottom, the door will stop or get up. So it aims to stop accident
once it happens;
running. Passing workers or vehicles can easily get aware that the door is
working and take special care to avoid accidents.
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. A interlocking passage system can solve this problem
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;
