Helium Liquefiers

Off-the-shelf and custom helium liquefiers and accessories in various configurations with outputs ranging from .25 l/hr to over 2500 l/hr. A helium liquefier is an open cycle process system where warm pure helium gas enters the system and is refrigerated to produce a pure liquid helium product stream. Helium liquefier product streams typically discharge into storage tanks or dewars for purposes of storage and distribution. Large (production scale) helium liquefiers are used by industrial gas companies to liquefy helium for cost-effective bulk transportation via vacuum insulated trailers. The bulk liquid helium product is delivered to either company-owned transfills where it is repackaged into smaller quantities for distribution and sale; or directly to end users where it is delivered into the customers’ storage tanks. Typically, smaller helium liquefiers are used in laboratories where liquid helium is used in smaller quantities for experimental purposes. In this application, the liquid helium is discharged into a larger dewar from where it is distributed to multiple points of use within the laboratory. Generally, the liquid helium used in this scenario boils in the experiment and is vented to atmosphere as a gas.
