Modernized vacuum furnace PZ 810 produced by former company Tesla. The furnace has vertical cylindrical chamber.

Parameters:

• Maximal batch size: width 350 mm, height 590 mm.
• Maximal long-term temperature 1400 °C. Molybdenum heating and shielding system.
• Vakuum: 5e^-2 Pa až 1 Pa (depends on batch type and temperature).
• Heating system: Molybdenum IR heating
• Maximal temperature rise rate: 1500°C per hour1
• Cooling: without inert coolant (natural in high vacuum)
• Cooling time: about 8 hours (typically)

Applications:

• Soldering and brazing: silver, copper and nickel alloys (Nicrobraz, e.g. see this manufacturer)
• Vacuum annealing
