Reefer Container Transport: Current Landscape and Future Trends

4/27/2025

 
As consumer demand for fresh food quality and safety continues to rise, the cold chain logistics industry is entering a period of rapid development. At the heart of this evolution lies the reefer container—the essential carrier for temperature-sensitive goods. As a specialist in reefer container solutions, TLS is committed to delivering efficient, safe, and intelligent cold chain transportation systems.

Why Is Refrigerated Transport So Essential?
Fresh produce and perishable goods spoil rapidly at ambient temperatures due to microbial growth and enzymatic activity. A controlled low-temperature environment significantly slows down these processes. At temperatures below -18°C, over 90% of the water content in food turns into ice, suppressing microbial activity and extending shelf life.

How Do Reefer Containers Work?
Reefer containers are equipped with independent mechanical refrigeration systems, capable of maintaining a wide temperature range—from +25°C to -25°C. TLS reefer containers, for example, are compatible with various international power standards and support pre-cooling, intermodal transport, and precision temperature control strategies. These features ensure that cargo remains within optimal temperature thresholds throughout the journey.

The State of Reefer Transport in China
Although China is now a global leader in reefer container manufacturing, the cold chain logistics infrastructure is still developing. Currently, only 10% to 30% of transported goods use refrigerated logistics—far behind the 80% to 90% in developed markets like Europe and the U.S. According to industry data, inadequate cold chain coverage results in over ¥70 billion (~$10 billion USD) in food loss annually in China.
However, this is changing. Driven by evolving consumer expectations and growing awareness of food safety, China's cold chain market has been expanding at a compound annual growth rate of 10%–15%. As a critical tool for long-distance, cross-regional delivery, demand for reefer containers is rapidly increasing.

How Are Reefer Containers Evolving?

1. Upgraded Materials for Greater Durability
New-generation containers use high-strength weathering steel like COR-TEN, offering enhanced corrosion resistance and structural stability across sea and land transport conditions.

2. Improved Thermal Insulation
Advanced insulation materials such as polyurethane (PU) foam are replacing older options. With thermal conductivity up to three times lower than traditional layers, combined with high-reflective coatings and optimized construction methods, energy efficiency is significantly improved.

3. Eco-Friendly Refrigerants
Legacy refrigerants like R12 and R22 are being phased out due to their ozone-depleting effects. Transitional refrigerants such as R134a and R404A are currently used, while research into natural, eco-friendly refrigerants continues to accelerate.

4. Energy-Saving Technologies
Variable-frequency compressors and fan systems allow the refrigeration unit to automatically adjust based on real-time demand, reducing energy consumption and improving operational efficiency.

5. Smart Refrigeration Systems
Digital controls are replacing manual operations. Modern scroll compressors offer better energy efficiency, compact design, lower noise, and even controlled atmosphere (CA) capabilities for gas environment regulation within the container.

6. Remote Monitoring & Smart Management
With the rise of IoT, wireless communications, and sensor technologies, reefer containers are becoming increasingly intelligent. TLS is exploring solutions involving temperature sensors, wireless modules, and remote monitoring systems to enable real-time tracking of internal conditions, system performance, and container safety.
This push toward greater visibility and automation improves response times in case of anomalies, boosts transport efficiency, and enhances safety across the cold chain network.

Looking Ahead
As cold chain logistics continue to thrive, reefer containers are entering a new era--smarter, greener, and more efficient than ever before. Whether in food, pharmaceuticals, or seafood exports, reefer containers are playing an increasingly vital role.
At TLS, we remain committed to innovation and sustainability. Our goal is to deliver next-generation reefer solutions that are not only reliable and efficient but also aligned with the future of intelligent logistics.

Refrigerated Containers: Exploring the Marvel of Cold Storage in Maritime Shipping

7/11/2023

 
Refrigerated containers, also known as refrigerated shipping containers, freezer containers, 20-foot refrigerated containers, or specialized refrigerated containers, are special containers designed for the transportation and storage of frozen and perishable goods during maritime shipping. They play a crucial role in transporting and preserving vegetables, fruits, meats, and other perishable items, ensuring that the goods remain fresh at specific low temperatures.

The greatest advantage of refrigerated containers used in maritime shipping lies in their excellent insulation and high mechanical strength. Polyurethane foam is commonly used in the industry to ensure effective insulation. When the density of polyurethane foam is 40 kg/m3, it provides the lowest thermal conductivity. In practical production, the density is slightly higher than 40 kg/m3 to ensure strength, minimize voids, and account for factors such as leakage during foaming. The wall thickness of maritime refrigerated containers generally ranges from 50 to 120 mm, while for specialized applications, it can be reduced to 30 mm.

Choosing the right refrigerated container is of paramount importance, especially for transporting perishable goods and temperature-sensitive medications. To ensure successful delivery of frozen products, the following factors are crucial: uninterrupted cold chain transportation, appropriate cooling technology, and selecting the correct insulation materials, dimensions, and container designs.

Different products have varying temperature requirements, making it essential to understand the temperature requirements for each product along the transportation route when selecting a maritime refrigerated container. For example, blood needs to be stored between 2-6°C, vaccines must be maintained between -70°C and -5°C, and frozen foods need to be kept at -18°C.

Refrigerated containers play a vital role in global trade, meeting the transportation needs of various frozen goods while ensuring product quality and safety. Through scientific and rational design and usage, refrigerated containers provide convenience and assurance, promoting the development of the food and pharmaceutical industries.

In conclusion, refrigerated containers are indispensable tools for transporting frozen and perishable goods via maritime shipping. With their exceptional insulation properties and mechanical strength, they effectively maintain the freshness and quality of goods during ocean transportation. Understanding the temperature requirements of different products and selecting appropriate refrigerated containers are key to ensuring the safe transportation of goods. The widespread use of refrigerated containers drives the development of global trade, providing convenience and reliability to people's lives.

What do you need to pay attention to refrigerated container | reefer container?

6/8/2022

 
How does the refrigerated container work?
The purpose of the reefer container is not to cool the product, but to maintain the temperature of the product. So instead of adding cool air, the refrigeration process removes heat from the air inside the container.
The reefer container distributes cold air from the floor through the T-deck.​

Precautions for the use of reefer containers
  1. During the loading process of the refrigerated container, turn off the power supply and confirm that the refrigerator stops running;
  2. Pre-cooling of goods: Before loading, the dunnage and other cushioning materials used in the refrigerated container should be pre-cooled, and the goods should be pre-cooled to the temperature required for transportation. containers are designed with limited cooling capacity and can only be used to maintain the temperature of the cargo. If the temperature of the cargo is too high, the refrigeration system will be overloaded, causing the system to fail and affecting the transportation of the cargo.
  3. About pre-cooling of refrigerated containers: In general, pre-cooling of refrigerated containers is prohibited, because as soon as the door of the pre-cooled refrigerated container is opened, the outside hot air will enter and meet the cold air in the container, which will cause water vapor condensation, and water droplets will damage the outer packaging of the goods and Label, water droplets condensing on the evaporator surface affect the cooling capacity.
  4. Preparations before packing: According to different perishable goods, the following items should be confirmed: ideal temperature setting; fresh air ventilation setting; relative humidity setting; total transportation time; cargo volume; packaging materials and packaging dimensions used;
  5. Be sure to load the goods reasonably and the maximum load height should not exceed the red load line of the container. Otherwise, the cold air circulation inside the freezer will be affected, resulting in poor wind circulation and even failure of the freezer insulation effect.
  6. The cargo must be placed on the edge of the T-floor to ensure even air circulation throughout the container.

What is a reefer container? What should we pay attention to when using it?

5/9/2022

 
A refrigerated |reefer Container is a closed container with refrigeration equipment and low thermal conductivity materials on the inner wall which is used to transport or preserve fresh fish, fresh meat, frozen food, fruits, vegetables, films, medicines and other required goods. 
Refrigerated containers are also divided into refrigerated containers and insulated containers.
  • The reefer container is generally equipped with a built-in refrigeration device at the front end of the container. When the freezer is working, the cold air is blown out from the ventilation pipe at the rear end of the container. Through the gap between the protrusion on the wall and the ventilation rail on the bottom of the container, the cold air suction port on the front end wall is returned to the freezer for circulation.In order to improve the cooling effect, the walls, top and bottom of the entire reefer container are covered with thermal insulation materials. The working temperature of the reefer container is between -28°C and +26°C. It can be automatically adjusted according to the needs of the goods to keep the temperature in the container unchanged.
  • Insulation containers are mainly used to load fresh goods such as fruits and vegetables. Generally, a refrigerant such as dry ice is used to prevent the temperature in the box from being too high; the usual holding time is about 72 hours. The inside of the container is completely heat-resistant.
Tips: 
Livestock and poultry meat
Include cattle, sheep, pigs, chickens, ducks, geese, etc. Usually, meat reaches a dormant state below -18°C, and if it is below -23°C, the refrigeration period can be doubled.

Frozen fish and aquatic products
The storage time of fish and seafood is closely related to temperature. Under normal conditions, the freezing period increases by a factor of 3 for every 10°C decrease in temperature. Low-fat fish has a shorter freezing period, while muscle red fish has a shorter freezing period.

Chocolate products
Shippers often ask to check that the humidity is set to 65%. Depending on the variety of chocolate, the temperature is usually between 8°C and 18°C.

Temperature control products
Goods that require temperature stability during transportation, such as films, medicines, food, etc. To avoid clumping and deterioration, the temperature was set between -2°C and 30°C.

Dangerous goods and harmful goods
Reefer containers maintain high standards and maintain quality for the transport of dangerous or sensitive cargo. This type of refrigerated container is distinguished by a particular color and logo.
​
Mixed refrigerated goods
Generally, it should be avoided to mix all kinds of fresh fruits and vegetables in the reefer container. Due to the volume, variety, cost and other reasons, pay attention to the temperature during transportation, Fruits and vegetables are mixed in containers. The closer the refrigeration temperature is, the better.

WHAT IS A REFRIGERATED | REEFER CONTAINER?

2/11/2022

 
Reefer containers|refrigerated containers are used to transport or store goods that require temperature control. Fruit, vegetables, dairy products, meat and other products are typical goods transported or stored in such containers.

At first glance, reefer containers look similar to traditional shipping containers, but they have many different features.
  • At the front of the container, you can set the temperature, ventilation and humidity of the container through the control box.
  • The grooves at the bottom of the container are called T-shaped decking, the air can circulate free underneath the cargo through them.
  • For cleaning the container, we have drain plugs in each corner. These can be closed for frozen goods. Nothing can enter from the outside into the container.
  • When loading goods, the height of the box should not exceed the maximum height set, certain space should be reserved for air circulation to ensure the thermal insulation effect of the cold air circulation in the container.
