High-temperature furnaces HFL 16/16 - HFL 160/17 have a sturdy cladding made from refractory insulation. This design offers better protection if the process produces aggressive gases or acids, such as when glass is melted. 

• Like high-temperature furnaces HT, except:
• Tmax 1600 °C or 1700 °C
• Robust refractory brick insulation and special backing insulation
• Furnace floor made of lightweight refractory bricks accommodates higher charge weights
• 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.
• 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
• Lift door
• Automatic door lock incl. door contact switch
• Heating elements protected against mechanical damage
• Ethernet interface
