  5. Design Highlights • Ergonomics • Highly accessible • Sliding panels • 3500C Max Temp • Lead Free Ready • Clamshell Cooling • Effortless access for maintenance • Convection Control • Heating and cooling

  6. Heater Layout

  7. Process Chamber • 350ºC Temp Rating • Lead Free Ready • Quality stainless steel construction • 6 Zones, 75 inches of heated length • Blower module with reduced size and weight • Easy access • 24” wide processing capability • Increased throughput • Single process chamber • No third lead screw required • eliminates dip in profile

  8. Heating Module Components Heating Element Scroll – 4 ports Orifice plate Blower wheel Static pressure sample port Overtemp T/C Control T/C

  9. Zone to Zone Control • Air intakes for each zone • Factory set • Allows fresh gas into process chamber • Improves individual zone to zone separation • Improves profile changeover time Adjustable air intake

  10. 3 phase Blower Motor 1/8 HP 2840-3400 RPM Air inlets Low Pressure (vacuum) High Pressure Heaters Blower Wheel Product Coming Towards You! Heated Air Plenum (Air HAP)

  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 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

  13. 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

  14. 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

  15. 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

  16. Air Cooling System Operation Air Inlet Lip Vent Exhaust 3-Phase Blower Motor Heated Section Direction of product travel Product Edge Conveyor Room air drawn into cooler Cooling air via forced impingement onto product

  17. Controlled Cooling Rate Cooling convection rate: 0.2 iwc Product Exit Temperature: 141.3C

  18. Controlled Cooling Rate Cooling convection rate: 1.2 iwc Product Exit Temperature: 105.9C

  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
