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.
