Refrigerated trucks, also known as reefer trucks, are specially designed vehicles that transport perishable goods at controlled temperatures. They are equipped with a refrigeration unit that keeps the cargo area cool, ensuring that items like fruits, vegetables, meat, and dairy products remain fresh during transit. These trucks play a crucial role in the supply chain, allowing businesses to deliver temperature-sensitive products over long distances. By maintaining a consistent temperature, refrigerated trucks help prevent spoilage and foodborne illnesses, making them essential for industries such as food distribution and pharmaceuticals.
