High speed spiral door also known as aluminum alloy fast door, is a metal industrial door integrating heat preservation, energy saving, sealing, high efficiency, wind resistance and environmental protection. It is an innovative product in the field of industrial technology. This high-speed door is not only resistant to strong winds, but also has a high degree of airtightness, reliability and practicality. The technology of the high speed spiral door is at a high level in the field of industrial doors. It can also ensure good sealing performance under high-pressure working environments, and can withstand strong winds exceeding grade 11.

     Fast operation: equipped with high-speed servo control motor, the speed is up to 2 meters per second, and can be adjusted independently; it supports high-frequency switching, can work more than 1,500 times a day, and runs more than 300,000 times without failure every year.

     High-strength material: high-quality aluminum profiles are selected inside and outside, and the core is high-density polyester foam

     Safety settings: The bottom edge is equipped with soft bottom airbag protection to prevent people from being accidentally hit. There is an infrared protection device on the aluminum alloy column, which can sense the vehicle personnel entering and leaving, so as to ensure that the door body will not drop when passing.

     Simple operation: the button on the right side controls on/off, and there is also an emergency stop protection device, which is easy to learn.

     Automatic or manual opening: The factory standard is manual button control, and manual devices can be selected: pull rope switch, card access control, remote opening; automatic induction: geomagnetic coil induction, radar induction.

Manual device: In the event of an emergency power failure, a reserve power supply is installed inside the electric control, and the door can be lifted and opened with the help of a balance system, which can effectively solve the problem that the door cannot be opened due to a power failure.

High speed spiral door and supporting equipment are widely used in: chemical industry, food, electronics, textiles, refrigeration, printing, supermarkets, precision machinery, logistics warehousing, office buildings, villas and other industrial and civil buildings.
