Whenever perishable cargo moves on deep-sea or long-distance routes, active reefer containers are the standard solution. These 20- or 40-foot ISO containers are fitted with a self-contained refrigeration unit that actively controls temperature and humidity within tight tolerances, regardless of ambient conditions. Power is supplied via shore connection at the terminal or the vessel's generator at sea; integrated alarms trigger immediately if power is interrupted. Typical cargo includes fresh meat, fruit, vegetables, fish, and temperature-sensitive pharmaceuticals. Unlike insulated containers without active cooling, reefer units continuously regulate the internal climate rather than simply retaining pre-cooled temperatures. When booking, freight forwarders must specify the required set point, humidity settings, and ventilation needs precisely, as deviations can result in cargo damage and liability claims.
