A refrigerated container (also known as a reefer container) is not just a means of transport, but it is also like a temporary 'home' for perishable products such as fruits, vegetables, seafood, and processed foods. With special manufacturing techniques, these containers not only ensure the quality of goods throughout the transport route but also protect consumer health. So what is the structure of a reefer container, what does a reefer container have? Let's find out!
What is the structure of a reefer container, what does a reefer container have?
Reefer container frame and shell
The shell and frame of a reefer container are the first two important factors that determine the durability and performance of this device. They act as a solid protective layer for the goods inside. The container shell is usually composed of multiple layers, each with its own function, creating an excellent protection system.

The outer shell of a reefer container is made from two main types of materials: stainless steel or aluminum. The outermost layer is not only a protective wall against external influences such as weather or collisions but also provides aesthetics for the container. Next is the middle layer, made of polyurethane (PU) insulation material with a thickness of about 60mm. This PU layer is like a warm coat for the goods inside, helping to maintain a stable temperature. Finally, the innermost layer is made of stainless steel to enhance the stiffness and durability of the container.
The technical specifications of the container shell include material components and thicknesses as follows:
- Outer layer Stainless steel/Aluminum 2-3 mm
- Middle layer Polyurethane (PU) 60 mm
- Inner layer Stainless steel 1-2 mm
Container frame
The entire container frame is made of stainless steel, providing sturdiness and high load-bearing capacity. Not only does it bear heavy loads, but it also resists corrosion, ensuring safety for goods in all climatic conditions. The frame is like the skeleton of a body, helping the container maintain its shape and protecting the internal components from deformation during transport.
Refrigeration system
This is the 'heart' of the reefer container; the refrigeration system is the factor that determines the ability to maintain the internal temperature, ensuring goods are not damaged. This system is not as simple as many people think.
Main components of the refrigeration system
Main components of the refrigeration system
The refrigeration system includes many different devices, of which the compressor, evaporator, and fan are the main components. The compressor operates like a pump, helping to circulate the refrigerant in the system. The evaporator has the task of cooling the air inside the container, and the fan distributes the cold air evenly.
Refrigeration system technical specifications:
- Compressor: Pumps refrigerant
- Evaporator: Cools the air
- Fan: Distributes cold air evenly
This system allows temperature adjustment from -30°C to 30°C, depending on the type of goods that need to be preserved. This is a very flexible temperature range that helps the container transport a variety of products.
Reefer container structure – Ventilation system
The ventilation system in a reefer container is not just an additional feature but also an indispensable part for some types of goods that need to be stored in a cool, airy environment.
Ventilation system features
This system helps circulate the air inside the container, creating conditions for fruits and vegetables to be served in the best environment. If compared to a regular refrigerator, the ventilation system in a reefer container is like a respiratory system, allowing air to circulate, helping everything inside to 'breathe'.
Benefits in transportation
Having an effective ventilation system not only keeps goods fresh but also minimizes the risk of mold and bacteria growth. This is especially important for perishable fruits and vegetables such as coconuts, dragon fruit, and durian – products that are mainly exported through transport units to the Chinese and Laotian markets.
Other supporting components
Other supporting components
In addition to the main components already mentioned, reefer containers are also equipped with many other supporting devices to ensure the quality of goods during transport. Specifically, they are:
Temperature sensor
A temperature sensor is one of the technologies used to monitor and maintain the temperature inside the container. This device is similar to the eyes of the container, helping users easily monitor the condition of the goods. Data from the sensor can be sent to the control system to adjust the temperature in a timely manner.
Control panel
The control panel allows users to customize the temperature and monitor the activity of devices within the container. This is user-friendly software that helps optimize the transportation process. With this system, manufacturers and shippers can easily track and adjust the temperature, ensuring goods are always in the best condition.
