I-Liquefier20 Compact Movable Helium Liquefier has a typical feature that the cold head inserts into the Dewar directly. The Helium compressor and the liquefier is integrated together and be skid-mounted into a small dimension, which is movable in the state of power-on. The liquid helium can be transferred into the customer’s device directly, no need a transportation Dewar so that the liquid helium consumption is avoided.
