After more than 30 years of service, the old Liquefier was replaced by a brand new Liquefier on Oct. 1, 2014. In preparation for the new Liquefier, over the previous year all of the gas lines going in and out of the old machine were modified, and the compressor discharge and return lines were completely replaced with bigger lines, allowing substantially more flow. The result of the improved plumbing and the new machine is a nearly 50% increase in Helium liquefaction rate over the best that the old machine could ever manage. See more pictures of the remodeled facility here.

In the spirit of recycling, and of recovering costs, the old Liquefier was sold to a Canadian company who will refurbish it and bundle it with related equipment before sending it on to Turkey, where it will have a second life, recovering boil-off Helium and reliquefying it for use in MRIs.
