Depending on the requirements and specific application, Linde Kryotechnik offers a range of standard and special systems for helium liquefaction. The helium liquefaction capacity of Linde systems ranges from 20 to more than 3500 liters per hour out of a single cold box.
The basic requirements for a user to size and design small to medium helium liquefaction systems are quite multilayer. The feed gas composition, for example, defines whether an internal adsober system can remove impurities or if a purifier (internal or external) is required, and if the purification operation is a continuous or batch process.
Furthermore, the liquefaction rate of the system is dependent on the running time, e.g. if the system is operated during the whole week or stopped on weekends and if a turn-down of the system is required. This will also determine the size of the liquid dewar and storage tank.
The circumstances determine whether the standard L-Series, variations of the standard equipment, or special systems deliver the solution.
