The springless free door cold storage door is a special door type suitable for cold storage. The following is its introduction:

Structural characteristics

-Door body:Usually made of metal materials such as stainless steel or high-quality galvanized steel plates, it has the characteristics of being sturdy, durable, and corrosion-resistant. The interior is filled with thermal insulation materials, such as polyurethane foam, to reduce the heat exchange inside and outside the cold storage. The surface of the door is flat and smooth, easy to clean and disinfect, and meets the hygiene requirements of the cold storage.

-Hinge:The use of specially designed eccentric axis hinges or self weight reset hinges replaces traditional floor springs or ordinary hinges, relying on the self weight of the door to achieve automatic closing and resetting, avoiding problems such as spring aging and damage, extending the service life of the door, and opening and closing more smoothly and quietly.

-Sealing components:High quality rubber sealing strips or sealing strips are installed around the door, which have good elasticity and cold resistance. When the door is closed, the sealing strips can tightly adhere to the door frame, effectively preventing cold air leakage and the entry of external hot air, ensuring the insulation effect and temperature stability of the cold storage.

working principle

By utilizing the principle of eccentric axis and self weight reset, when a person or vehicle applies a certain external force to the door, the door can open freely in both directions. After the external force disappears, the door automatically returns to its original position and closes completely by its own gravity, without the need for additional springs or electric devices to assist in closing.

Performance advantages

-Good insulation performance:High quality door materials and sealing design effectively reduce heat transfer, lower energy consumption of cold storage, and help maintain a low-temperature environment inside the cold storage.

-Convenient opening and closing:The two-way free opening method facilitates the entry and exit of personnel and vehicles, especially in cold storage environments where forklifts frequently operate, without the need for manual door closing, improving work efficiency.

-Safe and reliable:The door body has a certain degree of impact resistance, and will not be easily damaged after being slightly impacted by forklifts or other objects, and can be reset normally. At the same time, its automatic closing feature also avoids safety hazards such as cold air leakage caused by the door not closing in time.

-Health and Environmental Protection:The surface of the door is smooth, not prone to dust accumulation and bacterial growth, easy to clean and disinfect, and meets the strict requirements for hygiene environment in cold storage such as food and medicine. And it does not require electric drive, making it more energy-efficient and environmentally friendly.

-Easy installation and maintenance:The structure is relatively simple, the installation process is relatively easy, and there is no need for complex electrical equipment or pipeline laying, which can save installation time and cost. The later maintenance is also relatively convenient, mainly through regular inspection and cleaning of the door body, hinges, and seals, reducing maintenance costs and difficulties.

Applicable scenarios

Widely used in various types of cold storage, such as food cold storage, freezer, pharmaceutical cold storage, cold chain logistics warehouse, as well as buffer rooms, processing workshops, loading and unloading areas related to cold storage that require frequent access and high temperature control and hygiene requirements.
