CE Certification Insulation Cold Storage Doors Manufacturer, Exporter

Cold storage doors are essential components in the refrigeration industry, designed to maintain optimal temperatures for perishable goods. These specialized doors are commonly used in warehouses, supermarkets, and food processing facilities, where temperature control is crucial for preserving the quality and safety of products.
Typically constructed from insulated sandwich panels, cold storage doors help minimize heat transfer, ensuring that the internal environment remains stable. They come in various types, including sliding, hinged, and roll-up doors, etc. Each suited for different operational needs.

Product Description

Products Description
The difference between the cold storage insulated door and ordinary doors is that it needs to be insulated, because the cold storage insulated door is actually equivalent to an insulating structure that can be movable opened and closed, and is the only way for goods to enter and exit the warehouse.
The design and management of the cold storage insulation door is directly related to the service life of the entire cold storage. Due to the entry and exit of goods, the cold storage insulation door is opened frequently. When the storage door is opened, the hot and cold air inside and outside the storage is cooled and heated near the door opening. In exchange, the walls, floors, ceilings, etc. around the door opening are prone to condensation, dripping, frost, freezing and other phenomena. Therefore, in addition to trying to improve the heat and steam insulation performance of the cold storage door and strengthening the sealing performance of the door, some other effective measures must be taken, such as installing air curtains, setting up door buckets, electric heating, and other measures.

Anti-Collision Free Door
The door panel is made of 304 stainless steel panel and molded with polyurethane foam. Built in ABS observation window, ensuring the safety of personnel, transportation vehicles, and logistics in both directions. The flexible anti-collision board material effectively absorbs the impact force, prolongs the service life of the entire door body, and reduces the injury caused by accidental scratching of personnel passing through when the door body is opened and closed. After personnel or vehicles pass through, it automatically closes and the door leaf closes tightly. It can prevent the loss of cooling capacity and facilitate entry and exit.
