Refrigerated transport

Refrigerated transport uses specially designed vehicles, such as lorries, rail cars, aeroplanes, or cargo ships, fitted with on-board refrigeration systems that protect frozen and perishable foods from high ambient temperatures. These systems cool the air mass inside the cargo container and remove heat stored in the body of the vehicle, holding product temperature steady through loading, transit, and unloading. Maintaining this unbroken cold chain from factory to retailer is one of the most critical links in food safety and quality, since a single warm interval can undo days of careful chilled storage.
