Two types of containers are used in the process of refrigerated container
The majority of the reefers needs an external power supply. That is why they
are also known as 'plug-ins'. During sea-transportation as well as during
storage these plug-ins have to be connected to a power supply. During transit
transportation these plug-ins are seldomly being refrigerated.
- The integrated reefer container. This reefer has its own refrigeration
equipment built in.
- The port-hole container. This type of container has no refrigeration
equipment built in and is dependent on an external supply of refrigerated
air. The chilled air is supplied by a ducting system through an inlet in
the container and the warmed-up air leaves the container by an outlet.
During sea tranportation the port-hole container is being refrigerated by a
central refrigeration machinery. This circulates the air to and from the
port-hole container through pipes and couplings. During storage the port-hole
container is being refrigerated in a similar way. The port-hole container is
also rarely being refrigerated during transit transportation.
