RKN Coolcontainer

Dry ice Back to overview

To ensure a cool and safe transport of perishable goods – such as food , vaccines, drugs or blood plasma - Korean Air uses the RKN cool containers, a perfectly insulated lower deck cool container equipped with a dry ice cooling system.
Dry ice is the best way to maintain a low temperature and doesn’t leave any residue. It’s a perfect solution for preserving perishable goods during air transportation. Dry ice is stored in a waterproof box integrated into the left side of the container and can quickly be accessed from the outside by opening the hatch.
The cool container is made of high performance insulation panels to guarantee an optimal temperature. The door is also made of an insulated panel with rubber extrusions around the edges to ensure air-tight closure.

Result: an easy-to-handle high quality cool container which can easily withstand the harsh environment air cargo can be subjected to.


At times referred to as LD-3 coolcontainer.
