What is a Refrigerated Semi-trailer?

A refrigerated semi-trailer is a special transport vehicle specially designed for cold chain logistics, which can maintain a specific low temperature in the compartment during transportation. It is the core equipment of the cold chain transportation system, widely used in the transportation of temperature-sensitive goods such as fresh food, frozen products, medical supplies and industrial raw materials. Our refrigerated semi-trailers integrate advanced refrigeration technology and high-quality manufacturing process, with excellent insulation performance and stable refrigeration effect, to ensure the freshness and safety of goods in the whole transportation process.
Excellent Thermal Insulation Performance
Adopt international advanced "sandwich" composite board structure, with high-quality inner and outer skins and high-density polyurethane foam insulation layer, low thermal conductivity and good heat insulation effect. The fully sealed compartment and special sealing strips of the door effectively prevent cold air leakage and maintain stable temperature in the compartment.
Reliable & Efficient Refrigeration System
Support matching of domestic and foreign well-known brand refrigeration units, temperature control range from -25℃ to +18℃, which can meet the refrigeration and freezing needs of different goods. The refrigeration unit has the characteristics of high cooling efficiency, low energy consumption and stable operation, and can work normally in harsh working environments such as high temperature and long distance.
High Strength & Durable Structure
The frame is made of high-quality high-strength steel, formed by professional submerged arc welding and reinforcement process, with strong rigidity and fatigue resistance, and can bear long-term heavy load transportation. The compartment adopts integrated internal reinforcement rib design, with good corrosion resistance and long service life.
Lightweight & High Load Design
Adhere to the lightweight design concept, optimize the product structure on the premise of ensuring safety and load capacity, use lightweight materials for key parts, and the self-weight is lower than that of similar products. Effectively increase the actual cargo load, improve transportation efficiency and reduce operating costs for customers.
Humanized & Practical Internal Layout
Reasonable internal ventilation design of the compartment ensures uniform temperature in the car and avoids local temperature difference affecting the freshness of goods. The humanized design of the compartment door and internal accessories is convenient for loading, unloading and daily use of customers.
