Why IGS Systems ?

• Reduced connections.
• Fewer welds.
• Reduced Footprint.
• Lower Cost.
• Process improvement
• Less dead volume.
• ??????

75
Integrated Gas System

• High cost
• More Connections
• Welding still required
• Many different sealing systems
• Completely new parts inventory

76
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. ???
