17. Static Pressure What is Static Pressure?
Static pressure 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
Greater the static pressure, greater the heat transferred to the product
Static pressure ensures uniform convection from the plenum to the product

18. BTU Closed Loop Convection
Highest level of process control
Ensures repeatable heating and cooling, oven to oven, line to line, site to site
Transfer recipes line to line, plant to plant
Heating and cooling convection remains constant
Independent of temperature, voltage and altitude variations
Programmable range of IWC
