Easy and Economical

Purify industrial grade helium (4.8) into grade 5.0, 6.0 or even better and compress it into cylinders right at your facility

Helium Purifier A 1920x800

Helium Gas Purifier System

For Specialty Gas Applications

The Weldcoa Helium Gas Purifier System is designed specifically to purify Helium. It uses an activated carbon bed immersed in a liquid Nitrogen bath. It will remove the following impurities by freezing or liquefying: water, Carbon Dioxide, Oxygen, Argon and hydrocarbons. It will impede the flow of Nitrogen significantly to produce a very clean outlet stream of the source gas. This unit includes a powerful regeneration system to remove the impurities trapped within it, allowing for repeated use of the purifier traps.

features and benefits

Makes it easy and economical to purify industrial grade helium (4.8) into grade 5.0, 6.0 or even better and compress it into cylinders right at your facility.

  • Produce 5.0, 6.0 or possibly 7.0 grade Helium from your current source of product. The ultimate purity achievable is dependent on the level of contamination in the source gas and the flow rate through the purifier
  • Unit includes a regeneration system, allowing for repeated use of purifier traps
  • Versatile and Easy to Use
  • It is not necessary to place the purifier unit in a permanent location. The purifier will operate without electricity or Nitrogen gas. The unit may be place in proximity to cylinder filling operations and moved for regeneration
  • Skid mounted, turnkey solution is easy to set-up and start producing
  • Dual Swing Arm is provided to switch between purification mode and regeneration mode and ensure no cross contamination between Helium and Nitrogen
  • All process piping is orbitally welded where possible utilizing VCR connections to ensure high integrity and to prevent any potential leak points 
  • Each unit is shipped fully assembled and pre-tested.
  • Made in the USA
Helium Purifier C 1920x800

Regeneration Details:

This unit includes a powerful regeneration system to remove the impurties trapped within it, allowing for repeated use of the purifier trap. Here is a list of the requirements needed:

•  240 Volt Single Phase

• High Volume Low Pressure Nitrogen (Carrier Gas)

    -  100 PSI MAWP

    -  5 SCFM Nitrogen for 8 Hours

System Includes:

  • Aluminum Skid Mounted Base 
  • 260 Liter Open Top Dewar with an Activated Carbon Bed Material Assembly Installed Inside
  • Control Panel with a Selector Arm for Process and Regeneration Operations
  • 3000 SCFH Low Boy Ambient Vaporizer, 4000 PSI 
  • Back Pressure Regulator
  • Activated Carbon Filled Filter Cluster
  • All components are pre-piped with Stainless Steel tubing and face seal connections wherever possible
  • This system is production capacity sized

Note: A 1/2" Female VCR conection is provided for field connection. The fill manifold is not supplied with the standard model however is available as an add-on option. Please note, the intergrity of the fill manifold will be a key factor in the purity of the heilm from the system. 

Additonal Options Available:

  • Cylinder Securement Rack for 12 cylinders

  • Vacuum Pump System that includes a vacuum pump, stand and start/stop control box. All three items sold separately.

  • A 12 cylinder header (with rigid leads) integrated into the system. This is a great add-on feature because it allows cylinders to be filled right on the unit and it prevents any other leak points when directing the gas to an existing manifold.  At the end of the header there will be (2) additional  1/2" diaphragm packless valves for venting the header and pulling the vacuum.  The leads on the header are rigid 1/4" leads with VCR by CGA 580.
