FILLING PRODUCTS MANUAL SPECIALTY GAS GRAVIMETRIC FILL SYSTEM Produce Mixtures From % Down to PPB Concentrations Our Manual Gravimetric Fill Systems for specialty gas is designed to produce mixtures, (from up to 17 source gases) from percent down to ppb concentrations. Weldcoa provides a long list of technical options ensuring tha your system is customized to meet your specialy gas filling needs. Each unit is fully assembled, pre-engineered, oxygen cleaned and tested before it is delivered, making sure there are no leaks in the common piping. Installation is quick and easy. Safety Features and Benefits • Designed to 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)
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 Insert Gases For gases that may react due to other components due to their acidity or alkalinity
Blend Panels Available 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
• 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
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 mechanical joints
(Oxidizer will have brass compression fittings)
