Isothermal transportation — This is a type of cargo transportation in which a constant temperature regime is maintained in the body of the vehicle. They are necessary to preserve the freshness of food, live and cut plants, cosmetics, and some types of medicines. Isothermal vehicles are equipped with a reliable thermal insulation coating that allows them to maintain a temperature of -20...+12 °C. The difference between isothermal vehicles and refrigerators is that they do not have refrigeration equipment or heaters and maintain the temperature created inside using thermal insulation materials.
In addition, they are equipped with high-quality ventilation, which maintains the required humidity, which is also an important condition for the safety of some cargo. Therefore, transportation by isothermal vans may also be necessary for those goods that are not afraid of temperature changes, but require a special humidity regime, for example, furniture, bedding, some building materials, electronics, household appliances and much more.
For goods transported by rail, it is possible to transport them in isothermal wagons. In this case, you can choose a universal or specialized car designed for transporting a specific type of cargo. Universal cars are most often not equipped with ventilation, so they are not suitable for all types of products.
Rules for transporting goods in isothermal trailers
- Before transporting goods in isothermal trailers, it is necessary to assess whether it can withstand transportation with the parameters that are created in this vehicle. If necessary, the container is additionally wrapped in insulating material.
- When stowing cargo, it is necessary to provide space for air circulation, which will ensure heat removal and the required humidity.
- It is necessary to take into account the type of goods and do not mix food products that are prohibited for joint transportation, for example, fish, meat, cheeses, citrus fruits, vegetables with a strong smell.
- Before loading, the vehicle must be checked for the integrity of its thermal insulation layer.
- After loading, the temperature inside the body is measured and this data is entered into a log.
- After loading and unloading operations are completed, cargo compartments or containers are sealed and not opened until they arrive at their destination.
- If transshipment needs to be done, goods are moved from one container to another without additional storage outside the vehicle.
Only if all the specified rules are observed, the safety of cargo that is sensitive to environmental temperature parameters is achieved.
