Cryo Technology is widely used in generation, controlling and keeping environments/systems at low temperatures. A lot of electrical, mechanical energy is needed to get a system cooled down, to pump heat out of the system, either directly by closed cycle processes or indirectly using evaporation enthalpy of liquified gases. The whole cool down process is always contradicted by the natural heat transfer from warm to cold areas. A proper insulation is a must to minimize the energy amount needed to work against the natural heat transfer.
Vacuum insulation is the best option to avoid heat transfer. Our Spinning Rotor Vacuum Gauges are the ideal device to control vacuum insulation without breaking the vacuum.
Applications can be either for long term storage of gases and organic probes, chemical processing or to get into temperature regimes where special materials get superconducting.
Liquid Gases can be used for cooling, but could be themselves the matter of interest because of effective storage and transportation possibilities (relatively high volume and storage density compared to pressurized gases).
