To reduce heat input to an absolute minimum, a high technical vacuum is created between the inner and outer containers, ideally in the range of 0.05 to 0.001 mbar. However, the challenge lies not only in creating this vacuum but also in maintaining it for years with minimal maintenance. This is precisely where JAKOB’s innovative gas lock comes in.

Unlike a permanently installed vacuum valve, this solution offers a crucial design advantage: The gas lock can be completely detached from the container after the evacuation process. This prevents damage to the valve during the rigors of daily transport and eliminates potential leak points. Should the insulating vacuum weaken after extended use, the system allows for quick and easy re-evacuation of the insulation. This technology ensures that the cryogenic containers maintain maximum thermal efficiency over the long term.
