冷凍・冷蔵業界の断熱オーバーヘッドドア改修事例

Project Background and Challenges

In the cold chain logistics industry, warehouse energy consumption and temperature control are critical factors affecting operational costs and product quality. A major third-party logistics company operates several large cold storage facilities. Its old insulated doors had significant issues, including high energy consumption, poor sealing, and slow opening/closing speeds, severely impacting warehouse efficiency. To reduce operating costs and improve product storage quality, the company decided to comprehensively upgrade the cold storage doors.

The company's cold storage facilities primarily store temperature-sensitive food and pharmaceutical products, requiring high performance from the door's insulation and sealing. The original door body caused the cold storage temperature to rise in winter, increasing the load on the refrigeration system and significantly raising electricity bills. At the same time, poor sealing allowed cold air to leak from the cold storage, affecting product preservation and potentially causing product spoilage.

Additionally, the original manual or semi-automatic doors had slow opening and closing speeds. In frequent in and out operations, the wait time for door opening and closing was long, reducing warehouse throughput. To solve these pain points, the company needed a modern cold storage door solution that could meet the demands of high-efficiency energy saving, excellent sealing, and rapid opening and closing.

Solution: Anbixin Insulation Upward-Opening Door System

After market research and technical evaluation, the company chose the Anbixin Insulation Upward-Opening Door system. As a professional industrial door manufacturer, Anbixin has extensive application experience and mature product solutions in the cold chain industry. Its insulation upward-opening door system is designed specifically for cold storage environments and can effectively solve all the aforementioned problems.

• High Insulation Performance: The door body uses a multi-layer composite insulation structure with high-efficiency insulating materials, significantly reducing the cold loss of the cold storage. Compared to the original door body, the new door body's insulation performance is improved by about 30%, effectively reducing the energy consumption of the refrigeration system and achieving significant energy-saving effects.
• Excellent Sealing Performance: The door body is equipped with high-precision sealing strips and an intelligent sealing system, which can tightly fit the door frame and effectively prevent air exchange between the inside and outside of the cold storage. In the closed state of the door body, the sealing performance is far superior to the original door body, reducing cold loss from the cold storage and ensuring a stable temperature environment for product storage.
• Rapid Opening and Closing with Automation: The system uses advanced drive devices and control systems, with an opening and closing speed about 50% faster than the original door body, greatly shortening the wait time for in and out operations. At the same time, the door opening and closing process is smooth and low-noise, without disturbing the working environment inside the warehouse. In addition, the system supports integration with the warehouse management system (WMS), enabling automated control of the door body based on in and out needs, thereby improving operational efficiency.

Besides these core functions, Anbixin also provides customized door body dimensions and color schemes to match the original cold storage building style. The door body surface uses anti-corrosion treatment to adapt to the humid environment inside the cold storage. The system is also equipped with safety light curtains and emergency stop buttons to ensure the safety of operators.

Implementation Results and Customer Feedback

After the renovation project was completed, the Anbixin Insulation Upward-Opening Door system was put into operation immediately and achieved significant results. Through energy consumption comparisons before and after installation, the company's monthly electricity bill for the cold storage was reduced by about 15%, with considerable annual cost savings. At the same time, due to the improved sealing performance of the door body, the temperature fluctuations inside the cold storage decreased, effectively ensuring product storage quality.

Warehouse managers stated that the new door body's opening and closing speed was significantly faster, with in and out operation efficiency improved by about 20%. The door body's excellent sealing performance ensured more stable temperatures inside the cold storage, greatly reducing the risk of product spoilage. Additionally, the system operates stably with simple maintenance, reducing operational costs.

The cold chain logistics company was very satisfied with the overall performance of the Anbixin Insulation Upward-Opening Door system. They not only solved the original energy consumption and efficiency issues but also improved the overall operational level of the cold storage through the upgrade and renovation. Anbixin's professional service and technical support also received the company's recognition, establishing a good cooperative relationship between both parties.
