The core is equipped with advanced and efficient vehicle specific refrigeration units, supporting the optional installation of well-known domestic or imported brand units with equivalent power. The refrigeration technology is mature and can maintain stable temperature inside the cabin under various climatic conditions. The refrigeration temperature can flexibly cover the entire scene from -25 ℃ to+15 ℃, adapting to the transportation needs of multiple types of goods - it can complete the frozen transportation of meat, seafood and other goods, as well as the preservation and refrigeration of fruits, vegetables, dairy products, vaccines, drugs and other transportation scenarios with strict temperature requirements. At the same time, it can meet the transportation needs of chemicals that require specific constant temperature environments, effectively lock the quality of goods, and avoid deterioration or performance damage caused by temperature fluctuations during transportation. The refrigeration system operates reliably, has a fast cooling rate, can quickly reach the set temperature and maintain a constant temperature, while also considering energy conservation and environmental protection, reducing energy consumption and environmental pollution, and meeting modern environmental transportation requirements. The refrigerated compartment body is made of special specialized materials and is a fully sealed sandwich composite structure with excellent insulation performance. It can maintain stable temperature inside the compartment under harsh weather conditions, effectively block external temperature conduction, reduce refrigeration energy consumption, and ensure constant temperature inside the compartment during medium and long-distance transportation. The exterior of the compartment is made of high-quality materials, which are beautiful, durable and anti-aging. The internal skeleton structure is stable, and the middle is filled with high-density insulation layer, with low thermal conductivity and excellent sealing performance; The bottom of the compartment is equipped with anti slip flooring, which is easy to clean and can ensure the safety of goods stacking. Ventilation trough aluminum guide rails and meat hook compartments can be optionally installed according to needs to meet different transportation needs of goods. The exterior adopts a standardized edge and corner wrapping design, matched with tightly sealed components to prevent cold air leakage, further enhance insulation effect, extend the shelf life of goods, and at the same time, the cabin structure is sturdy, suitable for long-term high-intensity transportation use.
