The hot summer weather is the peak season for cold chain transportation. For friends who want to buy refrigerated trucks or insulated trucks to do fresh food business, they may have doubts about the difference between refrigerated trucks and insulated trucks. Below, the editor of Lengwang Refrigeration Unit will take a look at the differences between refrigerated trucks and insulated trucks from their manufacturing sources.

Refrigerated trucks are mainly composed of professional car chassis, cabin materials, and refrigeration units. It is mainly used for transporting goods with preservation and freezing temperature requirements. The basic configuration includes a refrigeration unit for the refrigeration device and a polyurethane insulated compartment for specialized transportation vehicles. Refrigerated trucks are mainly used for transporting frozen food, dairy products, vegetables and fruits, medicines and vaccines, etc.

Insulated trucks are specialized vehicles used to transport fresh and perishable goods such as fish, meat, fresh fruits, vegetables, etc. Due to the need to maintain certain temperature, humidity, and ventilation conditions during the transportation of such goods. Therefore, the interior of the insulated car is equipped with insulation materials, and the car is equipped with cooling devices, heating devices, temperature measuring devices, and ventilation devices, which have three functions: cooling, insulation, and heating; And refrigerated trucks are generally specialized vehicles used to transport frozen foods (refrigerated trucks), dairy products (dairy transport trucks), vegetables and fruits (fresh goods transport trucks), vaccines and drugs (vaccine transport trucks), etc., with cooling and insulation functions.

From the perspective of temperature control, refrigerated trucks refer to those equipped with refrigeration units that can reach temperatures of minus 10-18 ℃. They can not only maintain the temperature of the goods themselves, but also continue to freeze them. The temperature of the insulated vehicle can generally only be maintained at minus 3-4 degrees Celsius, which can only maintain the temperature of the goods themselves, and the farther the transportation distance, the greater the temperature difference.

In terms of transportation distance, refrigerated trucks are suitable for long-distance transportation of large quantities of goods, while insulated trucks are only suitable for short distance urban transportation of fewer goods.

Of course, in addition to the above differences, insulated trucks and refrigerated trucks have a lot in common, which is that they use the same manufacturing process for the compartment, which is the "sandwich" board bonding method assembled in pieces. Currently, the largest insulated refrigerated truck manufacturers in China adopt this technology, and the insulated refrigerated trucks produced using this technology have higher insulation performance.

The professional chassis of refrigerated trucks not only provides efficient and fast transportation efficiency, but also provides stronger energy supply for refrigeration units. The refrigeration units can ensure that the express delivery in the compartment reaches the fresh-keeping and refrigeration temperature, and the compartment materials can provide insulation, freshness preservation, and cooling effects, ensuring the stability and energy-saving of the temperature inside the refrigerated compartment. When selecting, choose according to the needs of the goods being transported.
