Cold storage rolling door – cold storage fast rolling door

　　Cold storage rolling door is a door product specially designed for cold storage environment. Its main function is to maintain the low temperature environment inside the cold storage, reduce the exchange of cold and heat, and ensure the freshness and quality of the goods. Cold storage rolling door usually has excellent insulation performance, fast opening and closing ability and high automation characteristics, which is an ideal choice for cold storage return room.

　　Features of cold storage rolling door

　　Excellent insulation performance: The use of multi-layer composite thickened door curtain and high-efficiency thermal insulation materials enables the cold storage rolling door to effectively reduce the exchange of cold and heat and maintain a constant temperature environment.

　　Fast opening and closing: Equipped with efficient drive system and servo system, it can complete the opening and closing action in a very short time, improve work efficiency and reduce the loss of cold air.

　　Anti-collision recovery: The door curtain adopts a special structural design, which has the ability to automatically derail and reset during the rising process, and can quickly resume working state even under accidental collision.

‌　　Multiple safety protection‌: Equipped with infrared photoelectric protection, airbag bottom edge and other devices, it can automatically stop or reverse when an obstacle is detected to ensure the safety of personnel and goods‌.

　　Structure and working principle of cold storage rolling shutter door

　　The cold storage rolling shutter door is mainly composed of door curtain, reel, motor, control system, track, sealing device and other parts. The door curtain is usually made of high-strength, heat-insulating and low-temperature-resistant flexible materials, such as PVC base cloth. When the opening signal is received, the control system will start the motor and drive the reel to rotate through the transmission device, so that the door curtain rises or falls rapidly along the track. When closed, the motor reverses, and the door curtain falls rapidly under the action of gravity and the tension of the reel to ensure the sealing effect‌.

　　Application scenarios and maintenance recommendations

　　Cold storage rolling shutter doors are widely used in key areas in cold chain logistics, such as cold storage return cages. These areas serve as buffer zones connecting cold storage with the external environment, and the thermal insulation performance of the door body is directly related to the temperature stability and energy consumption level inside the cold storage. In order to ensure the long-term stable operation of the cold storage rolling shutter door, it is recommended to conduct regular inspection and maintenance:

　　‌ Regularly check the door curtain and track: Make sure the door curtain is not damaged and the track is free of dust and debris.

　　‌ Keep the motor and transmission device clean: Prevent dust and moisture from affecting its normal operation.

　　‌ Check the sealing device: Make sure the sealing strip is not aged or damaged and maintain a good sealing effect.
