Reefer Container

A reefer container is a standard ISO container with a built-in refrigeration unit capable of maintaining temperatures from minus 35 to plus 30 degrees Celsius. The unit runs on external electrical power — provided by the vessel's power supply at sea, by gensets during road transport, and by power plugs at port terminals. Reefer containers include temperature controllers, data loggers, ventilation systems, and alarm functions.

Qatar's heavy reliance on food imports — including fresh produce, dairy, meat, seafood, and frozen goods — makes reefer containers essential infrastructure. Pharmaceuticals requiring cold chain transport (vaccines, biologics) also depend on reefer technology. Maintaining an unbroken cold chain from the overseas supplier's factory to the retail shelf in Qatar requires reefer containers for the sea leg, reefer trucks for inland transport, and cold storage warehouses between.

Modern reefer containers are equipped with data loggers that record temperature, humidity, and ventilation settings throughout the journey. Remote monitoring via satellite or cellular connections allows real-time tracking of conditions. At Hamad Port, reefer containers are plugged into power immediately upon discharge and monitored until collection. Temperature deviation alerts enable rapid intervention to prevent cargo loss.
