In the industrial, preservation, and processing sectors, maintaining stable temperatures in cold storages and cool rooms is a key factor determining product quality. Traditional doors often fail to meet speed requirements, leading to significant cold air loss, causing energy waste and affecting goods quality. Cold storage high-speed doors emerged as a breakthrough solution, helping businesses thoroughly solve this problem.
What are cold storage high-speed doors?

Cold storage high-speed doors are a specialized type of industrial door, specially designed for use in low-temperature environments such as cold storage, cool rooms, or clean rooms. The most prominent feature of this door type is its extremely fast opening and closing speed, usually from 0.6 m/s to over 2.5 m/s, much faster than conventional doors.
The door has a special structure with a multi-layer thermal insulation curtain and a tight rubber gasket system, helping to minimize heat exchange between the cold storage area and the outside environment. As a result, cold storage high-speed doors not only help save energy but also effectively maintain storage temperatures, ensuring goods quality is always at its best.
Structure of cold storage high-speed doors
To operate effectively in harsh environments, cold storage high-speed doors are composed of many advanced and specially designed parts:
Multi-layer thermal insulation curtain
The curtain is the most important part, usually made of thick PVC fabric, with multiple layers of thermal insulation padding inside. This structure helps prevent heat loss, maintaining stable temperatures. The curtain also has high durability, withstanding impacts and wind pressure well.
Door frame and guide rail system
The door frame is usually made of stainless steel (inox) or powder-coated steel, capable of resisting rust and corrosion well in humid cold environments. The guide rail system is specially designed to ensure the curtain moves smoothly without causing significant friction.
Sealing gasket system
Around the edges of the curtain and door frame, a system of rubber gaskets or specialized brush seals is equipped. These gaskets help the door seal tightly when closed, preventing cold air from escaping and hot air from entering.
Motor and transmission system
The motor of cold storage high-speed doors is a servo motor or high-capacity three-phase motor, integrated with an intelligent controller to adjust opening and closing speeds precisely. The motor is protected by a waterproof, moisture-proof casing, ensuring stable operation in cold environments.
Control devices and safety sensors
To optimize the workflow, cold storage high-speed doors are equipped with many modern control devices such as:
- Radar sensor: Automatically opens the door when detecting people or vehicles moving nearby.
- Photoelectric sensor: Detects obstacles while the door is closing, automatically stopping or reversing to avoid collision.
- Remote control: Helps users easily control the door remotely.
Applications of cold storage high-speed doors

Thanks to outstanding advantages, cold storage high-speed doors are widely applied in many industries:
- Food industry: Used in meat, seafood, fruit, and vegetable processing plants, helping to preserve raw materials and products at standard temperatures, preventing bacteria, and maintaining food safety and hygiene.
- Pharmaceutical industry: In vaccine, medicine, and medical product manufacturing plants requiring cold storage, high-speed doors help maintain clean room temperatures, ensuring product quality.
- Logistics and cold supply chain: Installed at distribution centers and frozen goods warehouses. The doors help optimize goods flow, reducing heat loss every time hydraulic pallet trucks or trucks enter or exit, thereby saving operating costs.
- Chemical industry: Some types of chemicals need to be stored in low-temperature environments. Cold storage high-speed doors help strictly control temperature and humidity, ensuring safety for the storage process.
