11. Static Pressure What is Static Pressure?
Static pressure is what is developed within the blower plenum to produce true forced convection
Why is Static Pressure important?
Static pressure directly relates to the amount of heat transfer an oven can deliver
The greater the static pressure the greater the heat transferred to the product
Static pressure insures uniform convection delivery from the plenum to the product

12. Thermal Effects of Convection Rate

19. Key Features / Options

20. Conveyor System 2-18inch width standard, belt or rail, 2-24” optional
Brush-less drive motor
Eliminates maintenance of changing motor brushes
Automatic chain lubrication
Minimizes downtime associated with chain lubrication
Flat flex or fine mesh belt

21. Conveyor System Roller system for adjustable edge rail
Stainless steel support shafts for EC and center support
Reduced friction
Ensures rail parallelism (within 0.040”)
Easy assignment fixed vs. moveable rail
Allows right to left field conversion

22. Advanced Conveyor Solutions
Precision center support
Basic center support
Chain pin lengths to 0.120”
Minimizes underside product clearance

23. Precision Center Support
Existing Design
New Design
The Existing RCS design on the left is complex and massive and requires an expensive dual drive shaft
The New Center support design on the right can be integrated to our low cost Rail Only drive.
We eliminated one Drive shaft and its associated costs by taking off the center support power transmission from the existing conveyor drive shaft.

24. Center Support Comparison
Smaller Chain in one extrusion shown on right replaces larger chain and 2 larger mass extrusions of the existing design.
Result is a 46% reduced mass and in smaller thermal footprint as well.
