Static & Dynamic Vacuum Insulation

We offer two types of vacuum insulation options for liquid nitrogen systems, tailored to meet your specific requirements:

  • Static Vacuum: In this option, the vacuum annular space is meticulously evacuated and sealed at the factory. The static vacuum insulation is designed to maintain a consistent level of vacuum throughout its lifespan, providing excellent thermal insulation for your system. This means that once the vacuum is created and sealed, there is no need for further evacuation or maintenance on-site.
  • Dynamic Vacuum: With the dynamic vacuum insulation, we provide a continuous on-site evacuation process facilitated by a vacuum pump. This type of insulation ensures that the vacuum annular space remains at an optimal level throughout the operation of your system. The dynamic vacuum insulation offers the advantage of adaptability, allowing adjustments to the vacuum level based on specific requirements or changes in operating conditions.

Understanding the differences between static and dynamic vacuum insulation options is crucial for selecting the most suitable solution for your liquid nitrogen system. Factors such as the frequency of use, required insulation performance, and operational flexibility should be considered when making this decision.

By offering both options, we aim to provide you with the flexibility to choose the vacuum insulation that aligns best with your needs. Please don't hesitate to reach out for further information or assistance in selecting the ideal vacuum insulation solution for your liquid nitrogen system.

The success of the super-insulation will depend on the following parameters:

  • Outgassing rate of the materials use within the vacuum annular space, such as spacers and radiation shield material
  • Absorption & adsorption rate of the getter and absorbent material use and its ability to perform long period scavenging of various type of gas molocule species form the vacuum annulus, in order to prolong the vacuum integrity
  • Wrapping design and technique to avoid linear heat conduction by the radiation shield itself which will result in increase of heat leaks
  • Bulk density of the radiation shield and spacer is very critical to ensure solid conduction is kept to the minimum. Increase in bulk density is know to increase solid heat conduction between layers of MLI
