The performance of the internal purifier has a direct impact on the liquefaction capacity of the helium liquefier. With increasing impurity level in helium, liquefaction capacity of the helium liquefier reduced significantly. In order to ensure the helium liquefier operates safely and stable, remove the impurities from the helium in the helium liquefier and improve the utilization of the...

Purification systems are necessary to support commissioning and operation of helium refrigeration and associated experimental systems. These systems are typically designed for a low level of impurity (i.e., in parts per million), since a 4.5 K or 2 K helium system will freeze out every other substance. The trace impurities can block and/or change flow distribution in heat exchangers and...

Helium is an expensive consumable in cryogenic facilities and is used widely in space, medical and energy research. In NSRRC, liquid helium is used as a coolant for cooling superconducting magnets and SRF cavities. Minor contaminants such as nitrogen, oxygen, moisture and oil will be picked up when liquid helium circulates in the large scale cryogenic systems, these contaminants will...
