Once perishable goods are loaded, the refrigeration unit takes over temperature control for the entire journey. A reefer container with integrated unit is an insulated 20' or 40' steel container fitted with a self-contained refrigeration machine that actively maintains a preset temperature throughout the voyage. The unit draws external power – from deck sockets aboard the vessel or from plug-in stations at terminals and depots – rather than relying on passive insulation alone. Operating temperature ranges typically span from around −25 °C to +25 °C, depending on cargo requirements. Standard cargo types include fresh produce, fish, meat, dairy products, and temperature-sensitive pharmaceuticals. Unlike insulated but unrefrigerated containers, which can buffer temperature fluctuations only briefly, the reefer provides precise active control – essential for intercontinental shipments where the cold chain must remain unbroken for weeks.
