Every day, hundreds of different trucks deliver a wide variety of goods throughout the country, from building materials to food. And while the former are unpretentious about the conditions, food is a special kind of cargo that needs to be transported in a special way. For different goods will suit different types of vans. Consider the main ones.
- isothermal, made by frame technology.
Such an isothermal van has a frame that creates additional bridges between the outer and inner skin of the body. Because of this, the heat output increases and its thermal insulation deteriorates. As a rule, the outer skin is galvanized steel. Foam plastic is used as insulator and its thickness can be 25-50 mm. The thickness depends on the thermal characteristics of the body, which are set. The foam used can be either embedded or glued. This kind of insulation can deteriorate with time, it is affected by precipitation, the difference in temperature between outside and inside, and vibration.
2. Isothermal made of sandwich panels.
Manufactured by frameless technology, so that the panels do not have cavities, which are thermal bridges. Sandwich panels are a single structure, consisting of an inner and outer layer and insulation. Panels can be three- or five-layered. When joining, the use of cushioning material and industrial adhesive eliminates heat loss and provides high strength. Such body will perfectly keep the temperature and its properties will not deteriorate during operation.
- Industrial Box Cargo Van
Using this type of body is an excellent solution for transporting cargo that does not require special temperature conditions. It can be made of plated or galvanized steel, as well as laminated plywood. It has a metal or wooden supporting frame inside. Interestingly, there have been cases when they tried to make an isothermal body out of an industrial goods body by pasting it inside with foam, but in order to keep such an “invention” in working condition, it required so much expense that it would be enough to make it.
