A refrigerated truck, commonly called a reefer truck, is a medium-duty delivery vehicle equipped with an integrated mechanical refrigeration unit that maintains precise temperature-controlled conditions inside an insulated cargo box, making it ideal for transporting perishable goods on local and regional delivery routes. They are heavily utilized across the food and beverage, grocery, foodservice distribution, pharmaceutical, floral, and catering industries, where maintaining strict cold chain integrity from origin to final destination is essential to product quality, safety, and regulatory compliance. Their compact 16-foot box size strikes an ideal balance between cargo capacity and urban maneuverability, allowing operators to service restaurant back doors, grocery loading docks, hospital receiving areas, and tight urban delivery points that larger refrigerated trailers simply cannot access.
