The high-temperature tube furnaces are available in either horizontal (type RHTH) or vertical (type RHTV) designs. 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 2
- Rectangular outer housing with slots for convection cooling
- Tube furnaces RHTV with frame for vertical operation
- Dual shell housing made 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 separate from furnace in separate floor standing cabinet
- Defined application within the constraints of the operating instructions
- NTLog Basic for Nabertherm controller: recording of process data with USB-flash drive
Additional equipment
- Charge control with temperature measurement in the working tube and in the furnace chamber outside the tube
- Display of inner tube temperature with additional thermocouple
- Gas tight flanges for protective gas and vacuum operation
- Manual or 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
- Process control and documentation via VCD software package or Nabertherm Control Center (NCC) for monitoring, documentation and control
