These compact tube furnaces with integrated control systems can be used universally for many processes. Equipped with a standard working tube of C 530 ceramic and two fibre plugs, these tube furnaces have a very good price/performance ratio.
Standard Equipment
- Tmax 1200 °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 fibre” (RCF), which is classified and possibly carcinogenic, is not used.
- Outer tube diameter of 50 mm to 170 mm, heated length from 250 mm to 1000 mm
- Ceramic working tube C 530 including two fibre plugs for operation under air
- Thermocouple type N (1200 °C) or type S (1300 °C)
- Solid state relays provide for low noise operation
- Heating elements on support tubes provide for free radiation
- Defined application within the constraints of the operating instructions
- NTLog Basic for Nabertherm controller: recording of process data with USB-flash drive
- Controller with touch operation B510 (5 programs with each 4 segments)
