Helium Gas Purifiers
The helium gas used in GWR Liquefiers
does not need to be high purity and can be supplied either from industrial
grade gas cylinders or from gas recovery systems. To increase the
number of times helium may be recycled by a recovery system before
the recovery system must be purged and refilled, GWR manufactures
helium gas purifiers capable removing impurities at levels of up to
10% of the gas composition, returning the helium to a grade of purity
suitable for liquefaction. The standard helium gas purifier operates
at a gas flow rate of greater than 20 standard-liters per minute.
