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. With it's high reliability and great performance, this container is indispensable to your cold chain.
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.
Like all our ULD's, this RKN is EASA certified and accepted by the FAA. This means we can guarantee it meets the industry’s highest standards concerning safety.

The RKN container is most suitable to ship deep frozen (-18°C / -0.4°F) and chilled cargo (8°C / 46.4°F).
You’ve studied the technical data sheet, browsed the operating manual and seen the product brochure, so you know the RKN is the right container for you. The next step is a personalised quotation. That’s easy. Just give us a few details, and our sales engineers will produce one for you. In addition to the price, you’ll receive product specifications, a technical proposal and delivery times.
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.
Room temperature: 20°C– 25°C (68.0°F - 77.0°F)
Chilled cargo: 2°C – 8°C (35.6℉ - 46.4°F)
Deep frozen cargo: <-18°C (<-0.4°F)
VRR supplies dry ice-based units. These units use dry ice as the cooling agent (–78.9°C).
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).
Yes, all of VRR’s cool containers have been fully tested in various ambient conditions. They have also been certified as airworthy by the relevant civil aviation authority.
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.
Yes, VRR has designed its own rechargeable battery system to equip its active containers. Some customers prefer this as it saves having to replace D-cell batteries, which can be expensive.
