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
Thermal Effects of Convection Rate Convection Rate Measured in In/H2O Low High Peak Temp 40 HZ 50 HZ 60HZ 70HZ • Effects of Low Convection Rate • Lower Peak Temp • Larger Peak Delta T • Thermal Uniformity Deteriorates • Effects of Increasing Convection Rate • Greater Peak Temp • Smaller Peak Delta T • Thermal Uniformity Improves
BTU Closed Loop Convection • Highest level of process control • Ensures repeatable heating and cooling transfer, oven to oven, line to line • Transferable recipes line to line, plant to plant • Heating and cooling convection remains constant • Independent of temperature, voltage and altitude variations • Programmable range of 0.5-1.5 IWC
Closed Loop Convection Control Furnace Control Unit Pressure Transducer 0-10 VDC Out Speed Controller Frequency Adjust RPM • Ideal for Lead Free applications • Stay within lead free process window • Controlled heating and cooling convection rates
Air Cooling System • 24 inch forced impingement air cooling • 1 top zone, bottom optional • Lowest exit temperatures • Best uniformity throughout the profile • Open / Closed Loop Control • Ensures repeatability • Controlled cooling rates • Clamshell design • Easy access for maintenance
