Compared to selecting a general truck chassis, refrigerated trucks also need to consider the stability of the chassis. The goods transported by refrigerated trucks are generally items that cannot be stored for a long time, and even with refrigeration equipment, they still need to be delivered to the destination quickly. At the same time, refrigerated goods have higher requirements for the transportation environment. If there is a malfunction on the road that causes the goods to deteriorate, the losses will be significant.

The compartment of a refrigerated truck is different from a typical box truck, as it requires good sealing and insulation functions to ensure that the refrigerated goods are in a stable temperature environment.
The design of refrigerated containers should first have air tightness and insulation functions. Generally, the structure of refrigerated trucks adopts a three-layer structure, and composite materials such as fiberglass, color steel plates, aluminum alloys, etc. are used for the exterior and interior skin.
The raw materials for the inner panel should be different depending on the transported goods, and the expensive inner panel should be made of stainless steel. The intermediate layer is made of insulation material, and polyurethane foam material should be selected first. High strength adhesive is used on the four sides to bond the glass sheet and polyurethane foam material together to form a closed plate.
In addition to materials, the thickness of the cargo compartment also determines the quality of insulation. The thicker the insulation layer of the cargo compartment, the better the insulation effect. However, the space inside the cargo compartment will be reduced, and the loading capacity of goods will be reduced. Users need to choose the appropriate thickness according to their actual needs.
Among the three major components of refrigerated trucks, the refrigeration unit is an important link. Due to the small cargo space, there are higher technical requirements for temperature control.
It is said that good goods are not cheap, and the price of imported refrigerators is also very expensive. For example, a set of imported refrigerators for a semi-trailer refrigerated truck, the new one is even cheaper and costs tens of thousands. Compared to other brands, domestic brands have a significant price advantage. For users who value price, domestic brands are also a good choice.
The power source of refrigeration units can be divided into two types: independent and non independent units. Independent units have a separate power source, and the diesel engine that is independent of the unit itself serves as its power source; The power output of non independent units is driven by the engine of the car chassis.
In terms of cost, the price difference between non independent refrigeration units and independent refrigeration units is over tens of thousands. If the budget is relatively surplus and the temperature requirements for the cabin are relatively low, it is recommended to use independent refrigeration units.
