Why IGS Systems ?
• Reduced connections.
• Fewer welds.
• Reduced Footprint.
• Lower Cost.
• Process improvement
• Less dead volume.
• ??????
Integrated Gas System
• High cost
• More Connections
• Welding still required
• Many different sealing
systems
• Completely new parts
inventory
The Facts
•
8 Component IGS Stick has 18
gasketed connections 36 seal
planes.
•
Welds are still required.
•
Reduced Footprint. Yes BUT $$$
•
Cost may be 3-4 X present.
•
Blocks & Gaskets = dead volume
•
Process improvement. ???
RHP Modular
• Low cost
—> Initial
—> Replacement
• Easily modified
• Same parts inventory
• Connections —> No Gasket
—> No dead volume
—> Fewer
Connections
• Weld free
The Facts
• RHP Has 8 gasket free connections.
• No welds required.
• Reduced Footprint. Yes.
• Cost same as present.
• No Blocks No Gaskets No dead volume
• = Process improvement.
