Helium Purifier
Cryogenic Helium Purifier
Introduction
Cryogenic Helium Purifier can improve the impure Helium into grade 5.5 (5.5 helium = 99.9995% purity) ultra-pure Helium gas by the following steps:
After pressurized by the inlet compressor, the impure Helium gas captured is removed moisture and oil through the oil-water separator, then it flows into the dryer unit to remove residual moisture and carbon dioxide, taking advantage of cryogenic condensation and freeze technology to remove the residual air impurity from the cold box pre-cooled by LN2 , which consists of a vacuum insulation vessel, the heat exchanger, phase separator and adsorber cylinder. Finally output the ultra-pure Helium gas and filling the gas cylinder bundles or container.
The main components of purifier include dryer unit, cold box, regeneration vacuum pump, gas distribution panel and control cabinet with compact skid-mounted structure.
Application
Cryogenic Helium purifier is typically applied in recovery and purification of the Helium for scientific research (specially to recover the impure Helium from refrigeration and liquefaction plant of superconducting machine), nuclear magnetic resonance (NMR), Helium liquefaction, balloon industry, optical fiber preforms sintering, leakage detection, etc.
