The difference between a cold-chain truck and a refrigerated truck

Cold-chain vehicles are a broad category that encompasses all types of transport vehicles capable of maintaining a specified temperature throughout the entire logistics chain, including refrigerated trucks and insulated vans, with an emphasis on end-to-end temperature control.

　　Conceptual scope

　　Cold-chain vehicles are a broad concept that encompasses all types of transport vehicles capable of maintaining a specific temperature throughout the entire logistics chain, including refrigerated trucks and insulated vans, with an emphasis on end-to-end temperature control.

　　Refrigerated trucks are a specific type of cold-chain vehicle, referring to enclosed vehicles equipped with refrigeration units and insulated bodies, designed to maintain low temperatures throughout the transportation process.

　　Core Functions and Temperature Control

　　In terms of temperature control ranges, refrigerated trucks offer a broader spectrum, including 2–8°C for fresh‑keeping, 0––5°C for chilled storage, and –10––18°C for freezing; by contrast, standard refrigerated vehicles are primarily designed for low temperatures, typically below 0°C, with some models supporting adjustable settings. Regarding temperature‑control stability, refrigerated trucks must maintain strict temperature management throughout the entire journey and continuously monitor temperature fluctuations, whereas standard refrigerated vehicles ensure low‑temperature conditions during transport but impose less stringent requirements for non‑transport phases such as loading and unloading. As for the cooling systems, refrigerated trucks generally employ advanced refrigeration equipment and high‑performance insulation materials, with some models featuring intelligent adjustment capabilities, while standard refrigerated vehicles rely mainly on mechanical refrigeration, with a few using phase‑change materials for cooling.

　　Applicable Scenarios

　　Cold-chain vehicles are suitable for the long-distance or complex supply-chain transportation of high-value, temperature-sensitive goods, such as pharmaceuticals, imported fruits, and frozen foods.

　　Refrigerated trucks are ideal for medium- and long-distance transportation of large volumes of perishable goods, such as meat and dairy products, or in applications with uniform temperature requirements.

　　Vehicle Structure

　　Cold-chain vehicles place greater emphasis on end-to-end temperature-control equipment, such as temperature recorders and remote monitoring systems, whereas refrigerated trucks prioritize the thermal insulation of the cargo compartment—e.g., polyurethane insulation—and the capacity of the refrigeration unit.

　　In short, a cold-chain vehicle is a “temperature-controlled transportation system throughout the entire journey,” while a refrigerated truck is “one of the tools used to implement the cold chain.” When making your selection, consider the characteristics of the cargo, the transport distance, and the required level of temperature control accuracy.
