- 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

Additional equipment
- 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.
- Furnace in HDB design featuring fresh air pre-heating, exhaust gas ventilation and an extensive safety package for debinding and sintering in one process, i. e. without transfering the material from the debinding furnace to the sintering furnace.
- Automatic control of vapor vent flaps
- Stainless steel exhaust gas hoods
- Catalytic or thermal afterburners
- Kiln furniture tailored to customer specifications
- Lift door
- Protective gas connector and seal of furnace casing to allow purging of furnace with protective gasses
- Manual or automatic gas supply system
Besides our wide range of electrically heated high temperature chamber furnaces we can also offer gas heated models designed to suit your requirements. Please contact us.
