Freezer door

　　● The freezer door is a door that is installed in the frozen environment equipment such as the freezer warehouse, refrigerated warehouse, etc. to be insulated and sealed.

　　● The freezer door adopts high-strength aluminum alloy door frame, which has high strength, no deformation, beautiful appearance and durable; the door is welded seamlessly with 2.0mm stainless steel edging around the door leaf.

　　● The door of the freezer door is usually foamed with a polyurethane pressure injection machine. The polyurethane structure is dense and uniformly fills all parts of the door. There is no shrinkage. The door is flat and beautiful, and it has a reliable thermal insulation performance.

　　● The guide rail of the freezer door is made of high-strength hard rust-proof aluminum alloy. The inside of the guide rail uses a floating and closed door opening system. When the cold storage door is opened, the sealing strips reduce the friction of the aluminum alloy door frame. When closed, the cold storage door is based on the door body. The aluminum alloy door frame is compressed by its own weight to achieve the sealing effect. The hardware and accessories are all made of stainless steel precision casting. The door has high precision, beautiful appearance and durability, which ensures that the cold storage door is light and flexible to open, safe and labor-saving, and easy to install. TPE environmental protection sealing strips make the freezer door have better sealing performance and performance.

　　● The door frame, sill and door leaf of the freezer door are equipped with two sets of electric heating antifreeze devices, which effectively prevent the freezing of the junction of the door and door frame of the cold storage room and the floor surface. There is a safety escape device in the storehouse: when someone is accidentally locked by mistake In the cold store, as long as the inner escape ring is pulled slightly, the door can be opened smoothly and escaped safely.

　　● The freezer door is generally matched with the air curtain machine, which can effectively reduce the loss of cold storage in the cold storage.

　　● There are generally two production methods for the freezer door: one is to spray the polyurethane tire foam into the pre-made frame, and the other is to use the heat insulation board.

　　● When making freezer doors, generally use poly-low-fat heat insulation board, because it not only has great strength, but also has a good heat insulation effect.

　　● Using patented concave-convex combination connection: It adopts factory prefabricated combined thermal insulation panel, and concave-convex combination connection, which is convenient for construction, disassembly, displacement and increase or decrease of storage capacity on site, so as to increase or decrease its storage capacity.

　　● The joint has superior strength and heat insulation performance: the new mechanism's concave and convex joint adopts a unique secondary locking technology, and the joint strength and heat insulation performance have been further improved.

　　● The freezer door is a high-density polyurethane cold storage door, which is welded with a 2.0mm stainless steel cladding integrated frame around it, which can ensure that the cold storage door will not be deformed for a long time. A heating wire is installed around the door leaf, which cooperates with the heating wire around the door frame to heat it to absolutely prevent moisture and frost.

　　● A safety device is installed on the door of the freezer: due to the use of a safety device on the door, you can easily escape if you accidentally close the person in the cold store.

　　● The combined cold storage is equipped with air pressure equalization valve: in the low temperature cold storage, it is equipped with an air pressure equalization valve to balance the air pressure difference between the inside and outside of the cold storage when opening the door or defrosting.
