A refrigerated truck-also known as a cold-chain transport vehicle or an insulated truck-is a specialized, enclosed box-type vehicle designed for constant-temperature or low-temperature transport.
Through the combined operation of a refrigeration unit and a polyurethane-insulated cargo body, it maintains the interior temperature within a preset range of -25°C to 15°C throughout the entire transport process (including loading, unloading, and transshipment).
By ensuring that perishable and temperature-sensitive goods remain in a stable cold-chain environment, it serves as a core transport vehicle within the cold-chain logistics system.
