Mechanical door sealed cold storage doors are mainly used for passages in low-temperature environments such as cold storage, playing a key role in sealing and insulation.

Structural characteristics

-Door body part:Generally, rigid polyurethane sandwich panels are used, with polyurethane foam in the middle and metal sheets on both sides. Polyurethane foam has extremely low thermal conductivity, which can effectively block heat transfer; The outer metal plate can enhance the strength of the door body, making it more sturdy and durable.

-Door seal section:This is its core component. It is made of elastic rubber material, and its shape is usually designed according to the fitting shape of the door and door frame, such as tubular, strip, and other forms. When the door is closed, the door seal is squeezed and deformed, tightly adhering to the door frame to fill the gap.

-Hardware accessories:Including door locks, hinges, handles, etc. The door lock can ensure the safety of the door after it is closed; The quality of hinges affects the smoothness of door opening and closing. Generally, sturdy and durable stainless steel materials are used to ensure that the door will not malfunction during long-term frequent opening and closing processes; The handle is convenient for personnel to open and close the door.

working principle

-When the cold storage door is closed, the door body squeezes the door seal, and the door seal material fills the gap between the door and the door frame due to elastic deformation, preventing external heat from entering the cold storage and also preventing cold air leakage.

Performance advantages

-Excellent thermal insulation performance:Effectively reducing heat exchange inside and outside the cold storage helps maintain a low temperature environment, reduce energy consumption of refrigeration equipment, and save energy costs.

-Good sealing effect:It can prevent external air, dust, and moisture from entering the cold storage, ensuring the hygiene and quality of goods inside the cold storage.

-Strong durability:The door body and door sealing material can withstand the test of low temperature environment and frequent opening and closing, and the quality of hardware accessories is superior, which extends the service life of the entire cold storage door.

Applicable scenarios

-Widely used in places that require low-temperature storage, such as food cold storage, freezer, and cold chain logistics warehouses.
