Nabertherm Tube Furnace 1700 Degree C (RHTH 80/300

The high-temperature furnaces are available in either horizontal or vertical design.High-quality insulation materials made of vacuum-formed fiber plates enable energy-saving operation and a fast heating time due to low heat storage and heat conductivity.By using different gas supply systems, operations can be performed under non-flammable or flammable protective or reactive gases or under vacuum.

• Tmax 1600°C, 1700°C or 1800°C
• MoSi2 heating elements, mounted vertically for easy replacement
• Insulation with vacuum-formed ceramic fiber plates
• Only fiber materials are used which are not classified as carcinogenic according to TRGS 905, class 1 or class 2
• Rectangular outer housing with slots for convection cooling
• Dual shell housingmade of sheets of textured stainless steel
• Ceramic working tube made of material C 799 incl. fiber plugs for operation under air
• Type B thermocouple
• Power unit with low-voltage transformer and thyristor
• Over-temperature limiter with adjustable cutout temperature for thermal protection class 2 in accordance with EN 60519-2 as temperature limiter to protect the furnace and load and with selectable maximum temperature gradient as tube protection
• Switchgear and control unit seperate from furnace in seperate floor standing cabinet
• Defined application within the constraints of the operating instructions
• NTLog Basic for Nabertherm controller: recording of process data with USB-flashdrive

Additional equipment

• Charge control with temperature measurement in the working tube and in the furnace chamber outside the tube
• Diaplay of inner tube temperature with additional thermocouple
• Gas tight flanges for protective gas and vacuum operation
• Manual and automatic gas supply system
• Three-zone control for optimization of temperature uniformity (Only tube furnaces RHTH)
• Check valve at gas outlet avoids intrusion of false air
