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.

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. 20ft and 40ft are usually the most common specifications for shipping, 2 units 10ft containers are usually combined into 20ft when they are transported.

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
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.
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.
