High-Temperature Furnaces with Molybdenum Disilicide Heating Elements and Fiber Insulation up to 1800 °C

Very good temperature uniformity and practical details set very high quality benchmarks.

Due to their solid construction and compact stand-alone design, these high-temperature furnaces are perfect for processes in the laboratory where the highest precision is needed. Oustanding temperature uniformity and practical details set unbeatable quality benchmarks. For configuration for your processes, these furnaces can be extended with extras from our extensive option list.

Standard Equipment

Tmax 1600 °C, 1750 °C, or 1800 °C
Recommended maximum working temperature approx. 50 °C below Tmax of the furnace. Higher working temperatures will increase wear and tear.
Dual shell ventilated housing made of textured stainless steel sheets for low surface temperature and high stability
Heating from both sides via molybdenum disilicide heating elements
High-quality fiber insulation backed by special insulation
Long-life roof insulation with special suspension
Temperature uniformity at 1450 °C up to +/− 6 °C according to DIN 17052-1
Exclusive use of insulation materials without categorization according to EC Regulation No 1272/2008 (CLP). This explicitly means that alumino silicate wool, also known as “refractory ceramic fiber” (RCF), which is classified and possibly carcinogenic, is not used.
Chain-guided parallel swivel door for defined opening and closing of the door
Two-door design (front/back) for high-temperature furnaces > HT 276/..
Labyrinth sealing ensures the least possible temperature loss in the door area
Reinforced floor as protection for bottom insulation as standard from models HT 16/16 upwards (distributed load 5 kg/dm²)
Vapor vent in the furnace roof with motorized exhaust air flaps, controlled via the extra function of the controller
Stainless steel exhaust hood as interface to customer’s exhaust system
Controller with touch operation P570 (50 programs with each 40 segments)
Defined application within the constraints of the operating instructions
NTLog Basic for Nabertherm controller: recording of process data with USB-flash drive

Additional Equipment

Cooling system to cool the furnace with a defined temperature gradient or with a preset fresh air volume. Both operating modes can be switched on and off for different segments by means of the extra function of the controller.
Safety package for debinding in air. Debinding technical ceramics is a critical process because of the hydrocarbons that are released. Hydrocarbons are flammable and there is a risk that a flammable mixture could form inside the furnace. Nabertherm offers tailored safety packages with respect to the process and the volume of binder that allow the furnace to be operated safely.
Thermocouple inlet with screw cap
Thermocouple for the heating control with calibration certificate
Protective gas connection to purge with non-flammable process gases (not completely gas-tight)
Automatic gas supply system with solenoid valve and rotameter, controlled by the extra function of the controller
Refractory brick floor insulation for a higher floor load (Tmax 1700 °C)
Lift door
Automatic door lock incl. door contact switch
Heating elements protected against mechanical damage
Special heating element qualities e. g. for zircon oxide applications
Ethernet interface
Process control and documentation via VCD software package for monitoring, documentation and control
