20' General purpose container with ventilation
Ventilated containers are also known as passive (naturally) ventilated or
coffee containers. Ventilation is provided by ventilation openings in the
top and bottom side rails. The openings do not let in spray, to prevent
depreciation of the cargo by rain or spray, for example.
If actively ventilated containers are required, i.e. containers with
adjustable ventilation, "porthole" containers may be used, which
simultaneously act as insulated or refrigerated containers. For more
detailed information, see under
Insulated and refrigerated containers.
Lashing rings, to which the cargo may be secured, are installed in the upper
and lower side rails and the corner posts. The lashing rings may take loads
of up to 1,000 kg. The common size for ventilated containers is 20'.
