1. Featuring annular radiator made from cooper tube in large diameter, vacuum gas quenching furnace delivers fast cooling effect.
2. Air nozzle is 360° deployed around heating chamber uniformly. As a result, optimal cooling effect ensures minimized deformation on workpiece.
3. Heating component is also 360° placed around the heating chamber, ensuring high energy efficiency, low heat loss and balanced heating effect.
4. It adopts new type of composite hard felt/metal shield as thermal insulation plate with heating function. Customers avail from outstanding resistance against heat, pressure and air scour, as well as prolonged service life.
5. Flexible programming input and stable mechanical performance ensure exceptional stability and low maintenance. Integrated safety system and failure alarms facilitate reliability.
