The secret lies in the highly complex double-wall technology, which was specially developed for the storage and transport of cryogenic liquefied gases such as nitrogen, oxygen, argon, or helium. In order to reduce heat input to an absolute minimum, a technical high vacuum is created between the inner and outer containers, ideally in the range of 0.05 to 0.001 millibars.

However, the challenge is not only to create this vacuum, but also to maintain it over many years in a maintenance-friendly manner. This is precisely where JAKOB's innovative gas lock comes in.

According to the supplier, this solution offers a decisive design advantage over a permanently installed vacuum valve: the gas lock can be completely separated from the container after the evacuation process. This prevents damage to the valve during rough everyday transport and eliminates potential leak points. Should the insulation vacuum nevertheless decrease after a long period of use, the system allows for quick and easy re-evacuation of the insulation. This technology is designed to ensure that cryogenic containers offer maximum thermal efficiency at all times.
