Helium is widely used in various fields, such as low-temperature superconductivity research, gas chromatography analysis, material heat treatment, pressure testing, medical technology, etc. As a rare resource, helium has been paid more and more attention from all walks of life. Based on its rarity and non-renewability, helium recovery systems are very popular. Here, helium compressors are used, which can reuse helium to reduce losses. Under normal circumstances, large enterprises will choose professional helium compressors.
