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
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)
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) • 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
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 gauge for 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.
Every System Includes
• Operator Console with HMI Touch Screen, Keyboard and Mouse, Printer and Audible Speaker • Powder-coated Steel Reference Enclosure With Load
Centering Sartorius 150 kg x 0.1g Gravimetric Scale • Source Gas Cylinder Storage Rack Built into Base • 6 or 10 Cylinder 316 Stainless Steel Orbital Manifold • All units with CGA 580 Fittings Supplied for Connecting to Target Cylinders • Up to (10) Supply Gases With Double Block & Bleed • Max. Service Pressure 3045 PSIG MAWP • Pirani Vacuum Gauge With O-ring Flange Connection
For Micron Readings • 1/4” or 1/8” Rigid Stainless Steel Leads • Individual Pneumatically Operated Cylinder Isolation
Valves on Leads • Static or Dynamic Vacuum • Integrated with the most recent version of AsteRisk’s
Specialty Gas Manager Software - Generates recipes for complex mixtures (%, PPM, PPB) - Automatically transfers to filling system software including pre-fill and post fill procedures - Produces DOT, FDA, OSHA and CGA Compliant cylinder labels - Performs post fill component calculations (actual) - Produces Certificates of Analysis s
Produce Mixtures From % Down to PPB Concentrations, Including EPA Protocol Gases
The Sur-Fill iQ-s™ Automated Specialty Gas Gravimetric Fill System puts automated technology at your fingertips. This easy to use system has touch screen technology that guides you through the specialty gas filling process, providing greater productivity and accuracy. The Sur-Fill iQ-s™ is capable of producing mixtures (from up to 10 gases) from percent down to ppb concentrations, including EPA Protocol Gases. Our system is integrated with AsteRisk’s Specialty Gas Manager software program.
Safety Features and Benefits
• Designed to produce mixtures from percent down to ppb concentrations, including EPA Protocol gases. • Unlimited number of recipes can be stored with up to 10 source gas supply stations • Intuitive HMI touch screen with self prompting features • Produces ultra-consistent mixtures • Uses significantly less labor to produce highly accurate mixtures • Runs unattended after the cylinders are connected and the mixture recipe is selected • Add-on feature provides remote monitoring capability and support • Includes a start-up and power loss recovery validation mode • Performs pigtail/lead deflection test prior to producing each mixture • Software keeps track of pressure and service cylinder contents • All process piping has been hydrostatically tested to 5250 PSIG to ensure quality and safety • Self-contained cabinet aids in reducing environmental influences to scale • Orbital fill head provides equal flow to each cylinder connected to manifold • Every morning, when logged into, the system performs an integrity check prior to starting the unit • 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) • Valves are high integrity diaphragm type stainless steel (Oxygen model has diaphragm packless 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.
