Transporting perishable goods at cold, controlled temperatures—typically between 0°C and 8°C (32°F and 46°F)—is the specialty of chiller van services. It has an insulated cargo area and a refrigeration unit that keeps goods, including fresh produce, dairy, drinks, and some medications, fresh and high-quality at the proper temperature. While the refrigeration unit, which is run on the car’s engine or an additional power source, continuously circulates cool air, the insulation blocks heat exchange. For the safe transportation of goods that are sensitive to temperature, chiller vans are necessary.
