Cold storage and refrigeration rooms operate at very low temperatures, making it difficult for standard industrial doors to function properly. This has led to the development of specialized cold storage doors, including cold storage sliding doors, cold storage swing doors, and cold storage high-speed doors.
Here's an introduction to these cold storage doors, their differences, and which type is best suited for specific cold storage environments.
Cold storage high speed doors are designed for environments that require frequent access and strict temperature control. These doors feature panels made of PVC and insulated material, ensuring excellent thermal performance to maintain stable internal temperatures. Equipped with advanced sensing systems, these doors automatically open and close when detecting movement, minimizing air exchange and reducing energy consumption. This is especially convenient for forklift operators or when handling goods, as there is no need for manual operation, saving time and effort. The lightweight yet durable structure of these doors ensures ease of maintenance and long-term reliability, making them suitable for a wide range of cold storage facilities. For added functionality, heating wires can be installed in the tracks to prevent freezing and ensure smooth operation. Cold storage high-speed doors can also be custom-made to fit specific dimensions, ensuring optimal sealing and operational efficiency.
Cold storage sliding doors are engineered for stability and durability in low-temperature environments. The door panels are typically constructed from high-strength galvanized steel or stainless steel, treated to resist corrosion in the humid conditions of cold storage. These panels are thick and filled with polyurethane foam for superior insulation, providing better thermal performance compared to high-speed doors. Sliding doors operate via tracks, which saves space and minimizes air exchange, helping to maintain consistent internal temperatures. These doors can be operated manually or with an electric motor; however, they are less suitable for facilities requiring frequent access due to their slower operation. Sliding doors can be customized to fit the structure and size of the cold storage facility, ensuring maximum efficiency and safety.
Cold storage swing doors are designed with convenience and safety in mind, making them ideal for small to medium-sized cold storage facilities. The door panels are made from high-quality steel, with surfaces treated to prevent rust and deformation in high-humidity, low-temperature environments. The swing design, connected via hinges, allows for simple and intuitive operation, making the doors easy to open and close manually. For improved thermal performance, swing doors are equipped with high-quality sealing strips to effectively block air exchange and maintain internal temperatures. Additionally, they are fitted with secure locks to enhance safety during non-operational hours. Swing doors can be tailored to the specific dimensions and structure of the cold storage facility for a perfect fit, ensuring optimal functionality and user experience. Maintenance is straightforward, requiring periodic checks of the hinges and seals to ensure long-term stability. However, swing doors are typically manual and cannot be motorized, making them most suitable for smaller cold storage applications.
The air curtain machine, as a supporting device for cold storage sliding doors, primarily functions to create an invisible air barrier that effectively prevents the exchange of air between the inside and outside of the cold storage, further enhancing insulation. Typically installed above the cold storage door, the air curtain generates high-speed airflow upon activation, forming a uniform air shield. This minimizes the exchange of hot and cold air during brief periods when the cold storage door is open, thereby reducing energy consumption. Additionally, the air curtain prevents dust and insects from entering the cold storage, maintaining a clean internal environment. With its compact design, easy installation, and low maintenance costs, the air curtain machine is widely used in various types of cold storage facilities. Its usage not only improves the operational efficiency of the cold storage but also extends the lifespan of the equipment. It serves as the optimal supporting equipment for cold storage sliding door systems.
