 The work chamber is constructed of 304L stainless steel and features Georgia Oven Company’s proprietary high strength gusseting system.  The interior of the chamber is fully welded, which adds strength and improves sealing capabilities. The chamber is passivated once all welding has been completed, leaving a clean, impurity-free finish.  Other features include:

• Custom Mineral Insulated or Quartz heaters, providing top, bottom and side chamber wall heat. 
• Multilayer insulation on the rear wall where chamber penetrations and ports are provided. 
• A top mounted powered or unpowered draft inducer port which aids in process cooling, maintains oven exterior at safe operator temperatures and reduces the amount of thermal loading to the surrounding environment. 
• The vessel door features Georgia Oven’s proprietary ultra-heavy gusseting system, providing anti-deflection capabilities during demanding thermal cycles.  Vessel doors utilize a multi-layer insulation system – maximizing efficiency, reducing losses and thermal loading to the surrounding environment.  The vessel door features multi-lay internal heat shields that produce a thermal drag between the work chamber and the vessel door, ensuring maximum safe operation and extended processing times.  Large-diameter, one-piece silicone door O-rings – for superior heat-resistance and sealing.
• Vacuum levels are achieved using simple single set-point direct acting solenoids, fully programmable from the F4AV Controller.  Accuracy is typically +/-2 Torr during vacuum and +/-1 Torr using a flow and pressure regulated backfill source.  A digital absolute vacuum transducer provides accurate and stable pressure level feedback to the F4AV Controller.  Typical operating control range is 760 to 1 Torr.
