Refrigerated trucks, also known as reefer trucks, are specialized vehicles designed to transport perishable goods at controlled temperatures. They are equipped with a refrigeration unit that maintains a cool environment, ensuring that items like fruits, vegetables, meat, and dairy products remain fresh during transit. These trucks are essential for the food supply chain, allowing businesses to deliver products over long distances without spoilage. The temperature inside a refrigerated truck can be adjusted based on the specific needs of the cargo, making them versatile for various types of perishable items.
