RKN cool container

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.
