Split-Type Tube Furnaces for Horizontal or Vertical Operation up to 1300 °C
By adding different gas supply packages, you can work in a protective gas atmosphere, with gases or in a vacuum.

Function and equipment
These tube furnaces can be used for horizontal (RSH) or vertical (RSV) operation. The split-type design makes it easy to change the working tube. It allows for a comfortable exchange of various working tubes (e.g. working tubes made of different materials).
Using a wide range of accessories, these professional tube furnaces can be optimally tailored for your process. By adding different gas supply packages, you can work in a protective gas atmosphere, with gases or in a vacuum. In addition to the convenient standard controllers, modern PLC controls can also be used to control the process.
Standard Equipment
- Tmax 1100 °C or 1300 °C
- Single-zoned design
- Dual shell ventilated housing made of textured stainless steel sheets for low surface temperature and high stability
- 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.
- RSV models with frame for vertical operation
- Split-type design for simple insertion of the working tube (opening temperature < 180 °C)
- Ceramic working tube C 530 including two fiber plugs for operation under air
- Thermocouple type N (1100 °C) or type S (1300 °C)
- Solid state relays provide for lownoise operation
- Heating elements on support tubes provide for free radiation
- RSH: switchgear and control unit integrated in furnace housing
- RSH: controller with touch operation B510 (5 programs with each 4 segments)
- RSV: switchgear and control unit separate from furnace in own wall or standing cabinet
- RSV: controller with touch operation B500 (5 programs with each 4 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
Additional Equipment
- Charge control with temperature measurement in the working tube
- Three-zone control for optimization of temperature uniformity
- Cooling systems for accelerated cooling of the working tube and charge
- Gas supply systems 1,15 or 2 for non-flammable process gas operation
- Gas supply package 4 for hydrogen operation
- Vacuum package to evacuate the working tube
- Process control and documentation via VCD software package for monitoring, documentation and control
