Refrigerated semi-trailer is one of the most important equipment in the cold chain transportation process. When choosing, one can usually start with the trailer chassis, insulation compartment, and refrigeration unit
1. Chassis selection
Generally, it is necessary to consider the type and quality of the transported goods, as well as the volume of the insulated cargo box, to determine the tonnage of the chassis. At the same time, the load-bearing capacity, fuel consumption, emission standards, and other factors of the chassis should be taken into account; In addition, due to the fact that the goods transported by refrigerated semi trailers are usually not storable for a long time, although equipped with refrigeration equipment, they still need to be quickly transported to their destination. If there is a malfunction on the road, it can easily cause the transported goods to deteriorate and suffer huge losses. Therefore, the reliability of the chassis should be given special consideration.
2. Box selection
The body of a refrigerated semi-trailer needs to ensure good sealing and thermal insulation performance. When selecting the body, attention should be paid to the material's water absorption, breathability, thermal conductivity, corrosion resistance, etc; And it is required that the cabin has good temperature stability and cannot affect other performance due to temperature changes.
Also, different types of goods have different requirements for the cargo compartment, such as customized hooks inside the compartment for refrigerated semi trailers transporting fresh meat; For delivery to supermarkets, multi temperature refrigerated trucks are required.
3. Selection of refrigeration unit
Refrigeration units are divided into independent units and non independent units, with independent units having separate power sources; Non independent units are driven by the chassis of the car and are much cheaper than independent units. When choosing, it is mainly based on transportation needs: for short distance distribution between urban or county areas, it is recommended to use non independent units, which are cheaper; For medium to long distance transportation, it is recommended to choose an independent unit.
