In industries such as pharmaceuticals, food, and cold chain logistics, cool storage facilities (5–10°C) are indispensable temperature-controlled storage spaces. Compared to cold storage facilities, cool storage facilities have moderate temperature requirements but also strict requirements for sealing, temperature control stability, and personnel and equipment access efficiency. In such facilities, selecting the appropriate industrial door is critical. Zipper-insulated rapid doors are the ideal choice for this temperature range, effectively balancing insulation and high-frequency opening and closing.
Special Requirements for Door Systems in Cool Storage Facilities
Cool storage facilities are primarily used for storing temperature-sensitive items that do not require freezing, such as vaccines, raw pharmaceuticals, dairy products, and fresh fruits. Their operational characteristics include:
Constant temperature control, requiring minimal heat loss during door opening and closing;
High-frequency access, requiring rapid opening and closing to minimize energy loss;
Clean environment, requiring door systems with antibacterial and dust-resistant properties.
Traditional PVC doors are ineffective at thermal insulation, and rigid doors have slow opening/closing speeds and low operational efficiency. In contrast, insulated rapid doors with a zipper structure excel in these areas.
Technical Advantages of Zipper Insulated Rapid Doors
Superior Insulation Performance: The door curtain is made of multi-layer composite insulation material with high-density foam filling in the center, featuring a thermal conductivity coefficient below 0.4 W/m²·K, effectively preventing heat exchange.
Automatic Reset Function: Thanks to its zipper structure design, the door curtain can automatically return to the track after minor collisions, extending service life and reducing maintenance frequency.
Rapid Opening/Closing System: Achieves opening/closing speeds of 1.2–2.0 m/s, significantly improving efficiency for forklift or personnel access and ensuring uninterrupted cold chain logistics.
Modular Structure: Easy to install, compact footprint, suitable for narrow entrance/exits of cool storage facilities; the control system supports multiple trigger methods including radar, ground magnetic sensors, and access control systems.
Actual Application Scenario: Performance of SEPPES Zipper Insulated Doors in Cool Storage Facilities
Take a pharmaceutical factory as an example. The temperature in its raw material storage cool zone is controlled between 5°C and 10°C, requiring frequent entry and exit operations. The project team ultimately selected SEPPES’ zipper-insulated rapid doors, installed at three access points, featuring a dual-sided radar system, high-seal door frames, and insulated composite curtain fabric. After three months of operation, the internal temperature fluctuation was less than ±1°C, with a 35% improvement in access efficiency, significantly enhancing temperature control stability and operational convenience.
Conclusion: Why are zipper-insulated rapid doors recommended for cool storage facilities?
Energy-efficient: Reduce cold air loss and lower energy consumption;
High-efficiency: Enable high-frequency rapid access and minimize waiting times;
Safety: Obstacle detection with automatic rebound and track self-reset to ensure equipment and personnel safety;
Aesthetics: Compact design suitable for clean and aesthetically pleasing environments.
Whether for new cool storage projects or retrofitting existing warehouse doors. Zipper-insulated rapid doors offer exceptional practicality and cost-effectiveness, making them a top priority for procurement managers to consider.
