As a fast door manufacturer that can be exported in China, SEPPES has been focusing on the production and development of industrial doors for 11 years. The fast door is the seventh-generation upgraded product. It has been continuously innovating in technology in accordance with European industry standards, and has a number of product core technologies. SEPPES export fast doors are widely used in food, medicine, chemical industry, textile, electronics, logistics, precision processing, warehousing and other industries due to their lightness and convenience, quick opening and closing, flexible operation, and long service life.

The biggest feature of the fast exit is its speed and opening method. Its function is closely connected with the control system. The opening methods mainly include: geomagnetic induction, radar induction, wireless switch, remote control, remote communication, pull rope switch, limited access control, dual Door interlock. Our most common are mainly geomagnetic, radar, wireless and so on. The editor mainly takes you to understand the principles of these three door opening methods.

1. Geomagnetic induction: The sensing object of the geomagnetic induction system is mainly metal objects, which need to be realized with the help of the ground induction coil. The principle of use is to use the ground induction coil formed by the ground induction wire to generate a magnetic field. The controller transmits the signal to the frequency converter to prompt the quick door body to open.

2. Wireless switch: After entering the sensing range, the sensor detects the change of the infrared spectrum and automatically turns on the load. When the load leaves, the delay is automatically turned off.

3. Radar sensing: It senses moving objects through microwave emission. When the moving object enters the launch area, the microprocessor will send a signal immediately, and the door will automatically rise to the top until the preset delay time is reached. After that, the door body will automatically lower.
