The RKN cool container (LD3 size) is perhaps the most versatile temperature-controlled ULD on the market. It not only maintains the internal temperature for several days but also fits a wide range of aircraft. It is perfectly compatible with 14 types of aircraft.
The RKN uses dry ice as the cooling agent. However, it is also equipped with a temperature control system that maintains the set temperature and logs the measured data throughout the entire journey.
The RKN container is most suitable to ship deep frozen (-18°C / -0.4°F) and chilled cargo (8°C / 46.4°F).

How much dry ice do you need?
Did you know you can easily calculate how much dry ice you need to keep your cargo cool until it reaches its destination? Check out our free Dry Ice Calculator!
Need an even bigger container?
If the RKN doesn’t offer all the cargo space that you need, check out our RAP container. This large main-deck cool container has the same great features, but it can hold almost three times more cargo than the RKN.
Looking for something special to ship unique or unusual cargo? We also create quality, customised ULDs that allow the safe transportation of heavy, odd-sized or high-value products. Each one comes with guaranteed global certification. Check out our ‘We Keep It Special’ product family.
Most vaccines are transported at a temperature between 2°C – 8°C (68.0°F - 77.0°F). Some vaccines require a temperature of 5°C (41.0°F), while the newer types of vaccines require a deep frozen temperature, which can be lower than -80°C (-112.0°F).
This depends heavily on the type of perishable. Fish, for instance, requires a deep frozen temperature of <-18°C (<-0.4°F), while some fruits and vegetables need to be kept at between 2°C – 8°C (35.6°F - 46.4°F).
Depending on ambient conditions, the set temperature can be maintained for several days. As an example, the RKN container has been tested to maintain a set point of 5°C (68.0°F) for 51.5 hours consecutively at an ambient temperature of 30°C. Please contact us for testing data per container.
There are two systems available. VRR cool containers are sold with a rechargeable battery, which can be re-used for multiple cycles. At request you can also buy containers that are D-cell battery powered.
