Storage Temperature Of Cold Storage Door

The thickness of the insulation board used below is shown in the table below:
Storage type Storage temperature/℃ Insulation board thickness/mm
Refrigerated room 0 100
Frozen storage room -15 100
Quick freezing room -30 150
There are types of doors such as swing doors, sliding doors, double doors, and lift doors, which can be manual or electric.
Manual sliding door: suitable for environments such as ordinary refrigerated warehouses, frozen warehouses, marine cold storage, constant temperature workshops, etc., where the temperature of the warehouse is not lower than -85 ℃ for civil and assembly warehouses. When the temperature difference between inside and outside the warehouse is greater than 50 ℃ and the relative humidity is greater than 90%, it can provide good insulation and sealing effects. Generally, a door leaf with a thickness of 106 millimeters is used, which solves various problems such as bulky manual cold storage doors, large footprint, and high cost of electric cold storage doors. It has its own unique features in opening, transmission, sealing, and other aspects. The door leaf is filled with polyurethane using a high-pressure infusion machine and foamed as a whole, providing reliable insulation and thermal insulation performance. The opening and closing of the door adopts a manual sliding and sliding type, and the track adopts a variable line type. When the door is in place, it will naturally fall and press down on the door frame and floor. When the door is opened, it will synchronously leave the door frame and rise, reducing the friction between the sealing strip and the door frame and floor, and extending the service life of the sealing strip. The sealing strip adopts a specially processed, low temperature resistant, oil resistant, and aging resistant high-strength, high elasticity hollow double tube rubber sealing strip. The upper, lower, and side of the door are equipped with adjustable compression devices, which have good sealing performance. This door also solves the problem of escape in the warehouse that many users are very concerned about. When the staff accidentally locks it in the warehouse, simply pull the inner escape ring slightly, and the door can be opened smoothly. Therefore, cold storage doors have the advantages of not absorbing moisture, not rotting, not easily deformed, lightweight, good thermal insulation performance, lightweight, not occupying space, and high safety. According to the size of the cold storage door opening, it can be divided into small storage doors, medium storage doors, and large storage doors. Cold storage doors with special circumstances and requirements can be specially processed.
