Structure
Door curtain : A stable sandwich structure formed by double-layer high-density industrial base fabric, double-layer aluminum mold, and insulation cotton, which is then pressed using a specially customized high-temperature cloth pressing machine for this product. The door curtain is neat and beautiful; Durable and long-lasting
The two sides of the door curtain are combined with specially customized zippers, which are machine pressed and have strong wear resistance
Total thickness of door curtain: 2cm
PVC thickness: 0.8mm-1.2mm
Track: The outer track is made of corrosion-resistant stainless steel compression
The inner track adopts specially customized polymer track and aluminum alloy track, combined with the zipper of the door curtain, which can enhance the sealing performance of the door opening.
Automatic repairer: assembled from specially customized molds
Motor: Special cold storage motors can be configured according to temperature, and waterproof, moisture-proof, antifreeze devices, frequency conversion and other systems can be freely configured and selected.
Product Features:
- The door curtain’s automatic repair function saves time and effort, eliminating the costly hassle of repairing the rolling shutter door after it gets hit and derailed by forklifts or other vehicles.
2.To a certain extent, the door curtain blocks the exchange of hot and cold air, eliminating the need to repeatedly close the steel insulated doors during work operations.
- With its fast opening and closing speed, the door allows quick passage during working hours—saving time while minimizing cold air loss.
Safety:
Every cold storage insulated rolling shutter door is equipped with a safety airbag at the bottom of the curtain. This airbag enables the curtain to open quickly if it hits an object or person while descending. Additionally, a dedicated cold storage infrared anti-pinch photoelectric sensor is available as an optional accessory, which can accurately detect people or goods without being affected by fog.
Wind Resistance:
In special cases where the rolling shutter door is relatively large, aluminum alloy wind-resistant bars can be added to enhance its wind resistance performance
Easy Installation:
Each cold storage insulated rolling shutter door of Yingli is made into a module before leaving the factory, including the door body, track, motor and control box, motor compartment, accessories, etc. When you receive the goods, you only need to assemble them together according to the installation video and fix them to the installed door opening. The debugging of the motor provides videos and files for you to view at any time.
In addition, if you encounter any problems that cannot be solved by video and file instructions, please feel free to contact us at any time. We have specialized technology to provide guidance for your door body to ensure that you can install and use it
Application field:
Full-Chain Scenarios of Food Cold Chain
- Food Processing Workshops (e.g., meat slaughtering and cutting workshops, aquatic product processing workshops, quick-frozen food production lines, etc.)
