The high-temperature furnaces have proved their excellence for many years now in producing technical ceramics. Optimum temperature distribution, very solid design and useful details provide for the necessary competitive edge with resprective quality.

Standard version, electrically heated (for gas heating, see page 21)

• Tmax 1600 °C, 1750 °C, or 1800 °C
• Furnace sizes from 4 to 450 liters
• High-quality molybdenum disilicide (MoSi2) heating elements
• Parallel swivel door, chain-guided, enabling safe opening and closing without damage to the fibre insulation in the collar area, protection of user from radiation from the furnace
• Door labyrinth sealing provides for optimum energy efficiency and temperature distribution
• Door area amored with stainless steel to avoid burn damages
• Reinforced floor as protection for bottom insulation as standard from models HT 32/16 upwards
• Over-temperature limit controller for product and furnace protection
• Furnace chamber lined with first-class, durable fibre material
• Special ceiling construction with high durability
• Long-lasting thermocouple, PtRh-Pt, Type B or Type S
• Vapor vent in the furnace roof

Besides our extensive line of electrically heated high-temperature chamber furnaces, we can also offer gas-heated models, customized to your application. Please contact us.

Additional Features

• Cooling fan For cycle time acceleration furnace sized specific fans are installed. The fan speed is preselected per segment. The controller is automatically switched on and off. Hence, different speeds can be applied e.g. for binder removal or cooling. With HiProSystems-Controllers, lenear cooling is possible.
• Air preheating Air preheating can also be used with our high-temperature furnaces. This allows the furnace to be used as a combi furnace for debinding and sintering in a single process (see also page 11).
• Start-up circuit A special circuit in the switchgear eliminates the problem of heating too fast when below 250 °C, typical for molybdenum disilicide heating elements, is eliminated. This feature is particularly recommended when firing ceramics which need sensitive handling in this temperature range.
• Automatic control of vapor vent flaps
• Customized furnace dimensions
• Stainless steel exhaust gas hoods
• Catalytic or thermal afterburners (see page 28)
• Kiln furniture
• Process documentation using temperature plotter or PC software
• Protective gas inlet and outlet, e.g. for reduction of oxygen content in exothermic debinding
