Oct 29, 2020· While the gas does have a variety of industrial uses, cryogenics is the largest single use of liquid Helium. It absorbs around the quarter of the total production of the gas. It's particularly used in the cooling of superconducting magnets with MRI scanners being its main commercial application.

Helium

Helium Separation/Purification. Because even 0.35% helium in a bulk-gas is considered a high-concentration, the first step is to separate the helium from the other components of the bulk gas stream. This can be accomplished through three principal technologies, which are often combined depending on the composition of the gas stream:

Cryogenics – The basics

With a Stirling Cryogenerator with integrated fan, you will get a flow of cold Helium gas directly out of the cooler. Just connect a (vacuum jacketed) line between the cooler and the application and you can start. Stirling's SPC-1 and SPC-4 cryogenerators (cryocooler) provide cryogenic cooling power in the range of 500 – 4,000 Watt at 77K.

Thermodynamics for Cryogenics

Depending on the application, our cryogenic systems or cryogenerators, can produce or (re-)liquefy cold gas. The type of gas or liquid depends on the application. Common for our systems besides Nitrogen are Oxygen, Methane Argon, Helium and CO2.

Helium Production | North American Helium

In order to understand the effects of helium contamination on a closed loop cryogenic vacuum system we first need to understand the fundamentals of a helium refrigerator. All helium refrigerators used to produce cold surfaces for cryopumps have three basic components: the helium gas (compressor), the connecting lines and the cold head ...
