Dewar technology progress

Why do cryogenic gas cylinders need to be evacuated regularly?

Content

With the development of technology, the design and function of Dewar bottles are also constantly optimized. Modern Dewars use advanced insulation materials such as vacuum insulation and multi-layer insulation to further improve thermal insulation properties. In addition, the integrated intelligent monitoring system can monitor the pressure, temperature and remaining amount of gas in real time to ensure safety and convenience of use.
