A reefer truck is a type of vehicle designed to transport perishable goods at controlled temperatures. It is equipped with a refrigeration unit that keeps the cargo area cool, making it ideal for transporting items like fruits, vegetables, dairy products, and pharmaceuticals. The temperature can be adjusted based on the specific needs of the cargo. These trucks are essential in the supply chain, ensuring that products remain fresh during transit. They are commonly used by companies in the food industry, such as grocery stores and restaurants, as well as by distributors of pharmaceuticals and other temperature-sensitive items.
