The Problem

Multiple stacked oven design restricted access from above Carrier gas manifold needed to be

serviced from the front

Bent tubing runs required for traditional manifold design Labor intensive

Non-standard design, higher engineering costs

The Solution

Carrier gas and purge air regulators of SP76 design

Modular manifold that scales up easily from 1 to 5 zones

The Results

From this …Multiple bent tubing runs

Multiple fitting points

• Multiple potential leak points

• Service access to regulators and gauges from above

• High labor and material content

• Non-standard engineering design

The Results

To this …

• Fewer potential leak points

• Easy access to regulators and gauges from the front

• Lower labor costs (no tube bends), lower material (less tubing)

• Standard, modular engineering design

All straight, pre-fab tube runs

Limited fitting points

Access to the regulators and gauges from the top is not required

Regulators and gauges are serviceable from the front
