With the wide application of cold storage in food, chemical, pharmaceutical and other industries, cold storage doors, as an important part of cold storage, are becoming more and more diverse. Here are a few common types of cold storage doors:
1. Translational cold storage door.
Translational cold storage doors usually consist of a door body, a drive system and a control system. The door body is made of double-layer color steel plate or stainless steel plate, and the inside is filled with polyurethane or other insulation materials to achieve good thermal insulation effect. The drive system usually uses a chain or wire rope, which is driven by a motor to move the door body left and right in the horizontal direction. The control system can be controlled manually, semi-automatically and automatically, and can be adjusted as needed. The translational cold storage door has good sealing performance, which can effectively reduce the loss of cooling capacity, and is suitable for large cold storage and high temperature and high humidity environments.
2. Lifting cold storage door.
Lifting cold storage doors usually consist of a door body, guide rails, a drive system and a control system. The door body is made of aluminum alloy or stainless steel, and the surface is sprayed with anti-rust paint, which has good corrosion resistance. The guide rail is made of stainless steel, parallel to the ground, which can bear large weight and ensure the stable operation of the door. The drive system is usually hydraulically or electric, so that the door body is raised and lowered in a vertical direction. The control system can be controlled manually, semi-automatically and automatically, and can be adjusted as needed. The lifting cold storage door has a simple structure and easy installation, which is suitable for small and medium-sized cold storage and low temperature and low humidity environments.
3. Folding cold storage door.
Folding cold storage doors usually consist of door panels, hinges, and a control system. The door panel is made of double-layer color steel plate or stainless steel plate, and the interior is filled with polyurethane or other insulation materials to achieve good thermal insulation effect. Hinges are used to attach the door panels so that they can be folded up. The control system can be controlled manually, semi-automatically and automatically, and can be adjusted as needed. The folding cold storage door has good sealing performance, which can effectively reduce the loss of cold capacity, and is suitable for large cold storage and environments that need to be opened and closed frequently. At the same time, the folding cold storage door takes up less space, which is easy to install and maintain.
Fourth, the fast opening cold storage door.
Quick-opening cold storage doors are usually made of aluminum alloy or stainless steel, which has good corrosion resistance. The upper part of the door is equipped with a slide rail, and the lower part is equipped with a guide groove, which allows the door to slide quickly in the vertical direction when opening or closing. At the same time, quick-opening cold storage doors are usually equipped with strong springs and counterweights to ensure the automatic closing effect and safety performance of the door. The quick-opening cold storage door is suitable for large cold storage that needs to enter and exit items quickly or open and close frequently, and its sealing performance is also good, which can effectively reduce the loss of cold capacity.
5. Airtight cold storage door.
An airtight cold storage door is a type of cold storage door with high sealing performance. It usually uses special sealing materials and structures between the door frame and the door panel to achieve a tight sealing effect. The airtight cold storage door is suitable for low temperature environments with high requirements for air tightness, such as cold storage, medicine storage, etc. Due to the good sealing performance of the airtight cold storage door, it can effectively reduce the loss of cooling capacity and maintenance costs, and also ensure the quality and safety of the goods.
To sum up, the common types of cold storage doors include translational, lifting, folding, quick-opening and airtight. Different types of cold storage doors are suitable for different environments and needs, so the choice should be based on the actual situation when choosing. At the same time, in order to ensure the normal operation of the cold storage and prolong the service life of the cold storage door, regular maintenance and maintenance should be carried out.
