The tube furnaces of series RS can be used for horizontal and with optional frame for vertical 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
- Heated length from 250 mm to 1000 mm
- Maximum outer tube diameter up to 170 mm
- 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 fibre” (RCF), which is classified and possibly carcinogenic, is not used.
- Tabletop model, mounted horizontally on an external switchboard including controller
- 2 m connecting cable in a protective metal conduit
- Split-type design for simple insertion of the working tube (opening temperature < 180 °C)
- Ceramic working tube C 530 including two fibre plugs for operation under air
- Thermocouple type N (1100 °C) or type S (1300 °C)
- Solid state relays provide for low noise operation
- Heating elements on support tubes provide for free radiation
- Controller with touch operation C550 (10 programs with each 20 segments)
- Defined application within the constraints of the operating instructions
- NTLog Basic for Nabertherm controller: recording of process data with USB-flash drive
