Standard refrigerated truck bodies are equipped with features such as Yufeng's standard rear closure door and full perimeter insulation on all doors. These features help reduce passive heat transfer, thus avoiding temperature fluctuations and preventing negative impacts on the cargo. Optional curtain strips can slow down temperature changes without hindering access. The various door sizes, configurations, and positions make it easy to access products in the cargo area at any time. These features ensure that the cargo stays at the desired temperature during transportation, which is crucial for perishable goods. The refrigerated truck body is an essential tool for businesses involved in the transportation of temperature-sensitive products. It provides a reliable and efficient solution for ensuring that the goods reach their destination in optimal condition.
