Why IGS Systems ?

  • Reduced connections.
  • Fewer welds.
  • Reduced Footprint.
  • Lower Cost.
  • Process improvement
  • Less dead volume.
  • ??????
slide-61
SLIDE 61

Integrated Gas System

  • High cost
  • More Connections
  • Welding still required
  • Many different sealing

systems

  • Completely new parts

inventory

slide-62
SLIDE 62

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

—> Initial —> Replacement —> No Gasket —> No dead volume —> Fewer Connections

  • Low cost
  • Easily modified
  • Same parts inventory
  • Connections
  • Weld free
slide-64
SLIDE 64

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.
