High speed Spiral Door is a door that enhances wind resistance and security by applying aluminum panels, which is a disadvantage of existing PVC high-speed automatic doors. With up to 2.0m/s fast operating speed, the 43mm thick panel is responsible for security and insulation. Also, for safe use, photo beam safety sensor and soft edge safety sensor can be applied to ensure safe use. It’s an innovative door that combines most of the technology from existing doors.
Based on these characteristics, it can be installed at all sites, including fire station, garage doors, industrial sites, underground parking lot entrances, luxury hotels, and freezer warehouses. However, there are disadvantages to these doors, which require more floor space on the top and side of the doors than on conventional doors, and are slightly more expensive than those of the same size.
High speed Spiral Door Common Features
Fast Opening And Closing
Like typical hangar doors, they provide a level of security that meets industry standards.
High Frequency Operation
The pull spring balance and chain drive system counteracts most of the resistance during the opening process.
Good
insulation
The total thickness of the door slat is 43mm and Has an excellent insulation performance with PU insulation.
Security
A 43mm thick aluminum slat provides safe and clean protection for the workshop.

OZ’s Spiral Door Special Features
Spiral door Slats with PU
The aluminum slats and PU foam are designed to provide light and sufficient insulation. Through this, any site can function as a door faithfully and quickly.
Spiral door Safety equipment
Manual release brake available to open the door in emergency case of power failure
When an object under the door is detected, the door stops.
encounter obstacles during the descent, stop immediately and run upwards.
Servo System with PMSM Motor and Helical gear
Helical gear allows the motor to be installed inside the spiral and is designed to utilize space efficiently. In addition, all wiring can be used safely at any time with correct connections through plugs and caps.
PMSM AC(permanent magnet synchronous motor). The motor uses rare-earth permanent magnet material, which is more efficient than traditional asynchronous induction motors. It has the advantages of energy saving, light weight, low temperature rise, large torque, and double overload. Door shaft direct – driven approach, less installation space.

OPTIONS for High speed Spiral Door
Switch
3 Point
Default 3-point switch (open/close/stop)
Proximity switch
contactless proximity sensor switch, suitable for places where hygiene is important or where there is a risk of infection.
Pull Switch
The PULL switch opens the door through the rope switch of the installed structure and is suitable for opening the door when on board the forklift.
Sensor
Motion sensor
The motion sensor has two sensors installed in one set at the upper exit and one set at the entrance, open the door when object is coming.
Vehicle sensor
The vehicle sensor opens the door by sensing metal (forklift, truck, hand-ift, etc.) through a magnetic field buried in the floor. It is highly stable and unaffected by the weather.
Windows
You can replace panels from specific heights to heights with full vision windows or add windows
Remote
It can be operated from a distance of up to 100M with a remote control, and can be installed to meet the customer’s request, such as multiple door operations with one remote control and one door operation with multiple remote controls.
Color
The default color is light aluminum. Additional cost and production period are required for custom color selection.
Logo & Lettering
Various phrases and logos can be printed on the door surface. We print accurately and neatly using CNC machine.
