Tube Furnaces and Accessories


Compact Tube Furnaces



The RD tube furnaces convince with their unbeatable price-performance ratio, very compact outer dimensions and their low weight. These all-rounders are equipped with a working tube which also serves as support for the heating wires. Thus, the working tube is part of the furnace heating which has the advantage that the furnaces achieve very high heat-up rates. The tube furnaces can be supplied for 1100 C or 1300 C. Both models are designed for horizontal application. If the customer requires protective gas atmosphere, a separate working tube incl. gas supply system 1, e.g. made of quartz glass, must be inserted in the working tube.
  • Tmax 1100 C or 1300 C
  • Housing made of sheets of textured stainless steel
  • Inner diameter of the tube: 30 mm, heated length: 200 mm
  • Working tube made of C 530 material including two fiber plugs as standard
  • Thermocouple type K (1100 C) or type S (1300 C)
  • Solid state relays provide for low-noise operation of the heating
  • Heating wires wound directly around the working tube resulting in very fast heat-up rates
  • Defined application within the constraints of the operating instructions
Additional equipment
  • 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
  • Gas supply system for non-flammable protective or reactive gas






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 fiber plugs, these tube furnaces have an unbeatable price/performance ratio.
  • Tmax 1200 C or 1300 C
  • Single-zoned design as standard
  • Dual shell housing made of sheets of textured stainless steel
  • Outer tube diameter of 50 mm to 170 mm, heated length from 250 mm to 1000 mm
  • Working tube of C 530 ceramic including two fiber plugs as standard equipment
  • Tmax 1200 C: Type N thermocouple
  • Tmax 1300 C: Type S thermocouple
  • Solid state relays provide for lownoise operation
  • Defined application within the constraints of the operating instructions
  • NTLog Basic for Nabertherm controller: recording of process data with USB-flash drive
Additional equipment
  • 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
  • Charge control with temperature measurement in the working tube and in the furnace chamber outside the tube
  • Three-zoned design (heated length from 500 mm)
  • Gas supply systems for protective gas or vacuum operation
  • Process control and documentation via VCD software package for monitoring, documentation and control


Tube Furnaces with Stand for Horizontal or Vertical Operation



These compact tube furnaces are used when laboratory experiments must be performed horizontally, vertically, or at specific angles. The ability to configure the angle of tilt and the working height, and their compact design, also make these tube furnaces suitable for integration into existing process systems.
  • Tmax 1100 C, 1300 C, or 1500 C
  • Compact design
  • Vertical or horizontal operation freely adjustable
  • Working height freely adjustable
  • Working tube made of C 530 ceramic
  • Type S thermocouple
  • Operation also possible separate from stand if safety guidelines are observed
  • Control system integrated in furnace base
  • Defined application within the constraints of the operating instructions
  • NTLog Basic for Nabertherm controller: recording of process data with USB-flash drive



High-Temperature Tube Furnaces with SiC Rod Heating Gas Atmosphere or Vacuum



These compact tube furnaces with SiC rod heating and integrated switchgear and controller can be used universally for many processes. With an easy to replace working tube as well as additional standard equipment options, these furnaces are flexible and can be used for a wide range of applications. The high-quality fiber insulation ensures fast heating and cooling times. The SiC heating rods installed parallel to the working tube ensure excellent temperature uniformity. The price-performance ratio for this temperature range is unbeatable.
  • Tmax 1500 C
  • Housing made of sheets of textured stainless steel
  • High-quality fiber insulation
  • Active cooling of housing for low surface temperatures
  • Type S thermocouple
  • Solid state relays provide for low-noise operation
  • Prepared for assembly of working tubes with water-cooled flanges
  • Ceramic tube, C 799 quality
  • Defined application within the constraints of the operating instructions
  • NTLog Basic for Nabertherm controller: recording of process data with USB-flash drive
Additional equipment
  • 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
  • Charge control with temperature measurement in the working tube and in the furnace chamber outside the tube
  • Fiber plugs
  • Check valve at gas outlet avoids intrusion of false air
  • Working tubes for operation with water-cooled flanges
  • Display of inner tube temperature with additional thermocouple
  • Alternative gas supply systems for protective gas or vacuum operation
  • Process control and documentation via VCD software package for monitoring, documentation and control
