transportation of various types of goods such as fresh fruits and vegetables, dairy products, frozen foods, and small medical supplies, focusing on the core requirements of "precise temperature control, long-term insulation, compliance and durability". It is equipped with professional electric refrigeration units and high-quality insulation boxes to ensure the quality stability of goods transportation in all aspects, completely solving the pain points of "inaccurate temperature control, insufficient insulation, easy loss of goods, and non compliant modification" in cold chain transportation. It strictly follows the original factory announcement standards, eliminates the risk of illegal modification, and ensures operational compliance.

The refrigeration box adopts the industry-leading "sandwich" composite insulation technology, which balances insulation and structural strength. The box panel is made of thickened 3.0 fiberglass inner and outer wall panels, filled with 8CM XPS insulation material in the middle, and hot pressed with high-strength adhesive. The outer frame is wrapped with 304 stainless steel and thickened aluminum profiles, and the accessories are 27 stainless steel door locks. The joints of the box are seamless and not glued, effectively blocking external heat conduction and reducing cold air leakage. The insulation effect meets the national A-level standard, providing a stable low-temperature environment for goods. The body size has been scientifically designed, with a total exterior size of 5995 × 2260 × 3300mm and a standard interior size of 4080 × 2100 × 2100mm. The corresponding standard effective volume is about 18 cubic meters, making it a high-capacity vehicle in the same class of 4.2-meter refrigerated trucks. It can fully meet the loading needs of urban supermarket replenishment, community centralized distribution, catering cold chain, short distance intercity cold chain and other scenarios, while balancing loading capacity and traffic flexibility.
