Gas Types Available

•  Oxidizer/Inert Gases

•  Inert Gases (with limited Oxygen 500 PSI or less)

•  Flammable/Inert Gases  

      (Flammable gases as defined by CFR-49. Gases that  pose a  

       hazard of ignition when combined with an oxidizer)

•  Reactive/Corrosive and Inert Gases  

      (For gases that may react due to other components

       due to thier acidity or alkalinity)

Blend Panels Available

 •  For Gases Filled By High Pressure Pumps

     - Requires master shut off valves

     - 1/2" brass pipe or stainless steel tube header

     - Swing arm with CPV type connections

•  For Gases Filled From Gas Storage (banks or single cylinders

     - Uses diaphragm packless valves

     - 1/4" stainless steel or monel tube header

     - VCR connections for most mechnical joints

 

Every System Includes: 

 •  Powder-coated, custom cabinet (pit or ramp style)

•  Custom Blend Panel with swing arm for up to 9 supply gases

•  6 or 12 cylinder orbital manifold with pigtails/leads

•  Satrorius high accuracy scale and scale indicator

•  Digital pressure gauge for high pressure readings

•  A compound vacuum gauge for vacuum readings

•  Pirani vacuum gaugefor micron readings

•  Typical interconnection piping is orbitally welded with VCR end connections

 

Additional Options: 

 •  Source Gas Cylinder Storage Rack

•  Micro-Cylinder for producing ppm components

•  Swing arm for premix cylinders for making diluted mixtures

•  A vacuum pump, stand, and/or vacuum pump starter control box

 

WARNING:

Our Manual Gravimetric Fill Systems are not intended or designed for blending flammable and oxidizer gases together. These gases MUST be kept separate from any one Manual Gravimetric Fill System otherwise there is a potential for a flash or explosion. The concern is having residual hydrocarbons on valve seats and then having high-pressure oxygen passing through those valves.

Safety Features and Benefits

  •  Designed ro produce mixtures with components from percent down to ppb concentrations from multiple source gases

  • All process piping has been hydrostatically tested to 5250 PSIG to ensure quaility and safety

  • Self-contained cabinet aids in reducing environmental influences to scale

  • Orbital fill head provides equal flow to each cylinder connected to manifold

  • A digital vacuum compond gauge, digital high pressure gauge and digital micron meter are all included for accurate readings 

  • Relief valves are installed for over pressure protection during the fill process

  • All components are orbital welded and mostly VCR connections. (Oxidizer/Inert model has monel tubing with compression fittings)

  • All piping components manufactured by Weldcoa have been cleaned for oxygen service per: PSGP Oxygen Cleaning Procedure #PSMB-O2 CLEAN 

  • All GasFlow manual valves and check valves have been cleaned by GasFlow per CGA G4.1-2009 (practive for cleaning methods and cleanliness levels for material and equipment used in oxygen-enriched enviornments)   

  • Valves are high integrity diaphragm packless type (Oxygen model has mechanically sealed monel/brass)     

  • The entire manifold assembly, including the leads, are 100% hydrostatically pressure tested to 1.5 times the MAWP, 100% nitrogen leak tested, 100% oxygen cleaned, dried, bagged to the highest safety standards. 

  • Installation is quick and easy. System is delivered assembled, oxygen cleaned, pressure tested and ready to go. Simply uncrate the unit, position it in place, anchor it to the floor and connected it to the existing plumbing.
  • Made in the USA
