 The work chamber is constructed of 304L stainless steel and features our unique proprietary high strength gusseting system.  The interior of the chamber is fully welded which adds strength and improves its sealing capabilities. Chambers are then passivated once all welding has been completed leaving a clean impurity free finish.  Other features include

• Proprietary constructed Mineral Insulated or Quartz heaters (depending on application) heat the top, bottom and side chamber walls. 
• Our Multilayer insulation technique is used on the rear wall where chamber penetrations and ports are provided. 
• Top mounted draft inducing is recommended for applications over 302°F (150°C).  Unpowered draft inducers should be connected to a negative pressure in-house exhaust system.
• The vessel door features our unique ultra heavy gusseting system, which offers anti deflection capabilities during demanding thermal cycles. Vessel doors are fully insulated using our multilayer type procedure maximizing efficiency, reducing losses and thermal loading to the surrounding environment.
• One-piece constructed large diameter silicone door O-ring offers superior heat resistance and sealing. 
• Vacuum levels are achieved using simple single set-point direct acting solenoids, all fully programmable from our 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 expressed in Torr, 760 to 1, but can be easily set-up for 0.0 to 30.0-inches of Mercury.
• Sealed and pressurized electrical housings on all electrical components including heaters, control system and all motors.
