Guide to protective devices for enhanced security using high-speed rolling PVC doors
High-speed rolling PVC doors are known for their outstanding features, including thermal insulation, collision resistance, insect-proofing, wind resistance, dust protection, and sound insulation. These doors offer rapid operation, making them ideal for production spaces with stringent environmental requirements, such as food processing, electronic workshops, printing and packaging facilities, chemical plants, pharmaceutical companies, dust-free workshops, and logistics and warehousing areas.

Emergency Stop Button
An emergency stop button plays a crucial role in high-speed rolling PVC doors. When pressed, it instantly cuts off the power supply to the curtain’s operation and interrupts the power circuit controlled by the Programmable Logic Controller (PLC).
Bottom Airbag Device
The bottom airbag device comprises a receiving end and a transmitting end. The transmitting end controls the air pressure switch and the sending circuit. Positioned beneath the door curtain, the bottom seal of the airbag triggers the air pressure switch when encountering obstacles or individuals during descent. In such cases, the door immediately halts its descent, reverses direction, and ascends to the top. Once the obstruction is removed, the door resumes its downward movement. This safety feature operates seamlessly in both manual and automatic modes, ensuring the well-being of people and vehicles.
Photoelectric Protection Device
High-speed rolling shutter doors often incorporate a reflective photoelectric switch with a sensing range of 0-5 meters. These switches are typically mounted on the door pillars at both sides. During automatic descent, if an individual or object obstructs the sensor’s path, the door promptly ceases its descent and retracts to the top position. Once the obstacle is cleared, the door automatically lowers. This functionality remains effective in both automatic and manual modes.
Safety Light Curtain Device
For enterprises with high-frequency door usage, the safety light curtain device is an excellent choice due to its larger contact area compared to safety photoelectric sensors. The light curtains, installed on both sides of the door frame, emit strips of sensing light. Triggering either of these curtains immediately stops the door’s operation and causes it to ascend rapidly, providing enhanced safety.
In summary, the above information highlights the four essential safety protection devices for high-speed rolling PVC doors. When selecting high-speed doors, manufacturers should carefully choose the appropriate safety protection devices based on their specific operational requirements. Prioritizing safety ensures a secure working environment in industrial facilities. AGCO Agricultural Machinery Co., Ltd., a Fortune 500 company, chose SEPPES as their industrial door supplier.
