Generally speaking, for short distance distribution and loading of goods between urban areas or districts, there are fewer options for using medium and light truck chassis. However, for long-distance transportation with larger transport volumes, medium and heavy trucks or semi trailer refrigerated trucks are preferred.

Compared to choosing a regular truck chassis, refrigerated trucks also need to focus on the stability of the chassis. The goods transported by refrigerated trucks are usually items that cannot be stored for a long time, and although they have 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 very significant.

The body of a refrigerated truck is different from that of a regular box truck. It requires good sealing performance and thermal insulation effect to ensure that the refrigerated goods are in a stable temperature environment.

The design of refrigerated containers mainly focuses on air tightness and insulation performance. The structure of refrigerated trucks usually adopts a three-layer structure, and the inner and outer skins are made of composite materials such as fiberglass, color steel plates, aluminum alloys, etc.

The material of the inner panel should be different depending on the transported goods, and the expensive inner panel should be made of stainless steel. The middle layer is made of insulation material, mainly polyurethane foam material. 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.

In addition, different products have different requirements for the trunk. For example, refrigerated trucks transporting fresh meat require customized hooks on the cargo compartment; The refrigerated trucks used for store delivery have small batch sizes, multiple varieties, and require multi temperature layer refrigerated trucks; Different temperature requirements and frequent loading and unloading require multiple refrigerated trucks with open doors. All of these can be customized from the cabin factory according to specific needs.
