Rotary Tube Furnaces for Batch Operation up to 1100 °C

The rotary tube furnaces of the RSRB series are suited for batch operation.

The rotary tube furnaces of the RSRB series are suited for batch operation. The rotation of the working tube ensures that the charge is in motion. Due to the shape of the quartz reactor with the tapered pipe ends the batch is kept in the rotary tube furnace and can be heat-treated an arbitrarily long time period time. A controlled heating to the temperature profiles is also possible.

Standard Equipment

Tmax 1100 °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.
Thermocouple type N
Solid state relays provide for lownoise operation
Heating elements on support tubes provide for free radiation
Tube furnace designed as table-top model with quartz glass reactor which opens on both sides, tapered ends
Reactor is removed for emptying out of the rotary tube furnace. Beltless drive and hinged furnace housing (opening temperature < 180 °C) provide for very easy removal through
Adjustable drive of approx. 1-40 rpm
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 prgrams with each 4 segments)

Additional Equipment

Charge control with temperature measurement in the working tube
Three-zone control for optimization of temperature uniformity
Reactor open on both sides, made of quartz glass with knobs for better mixing of the charge in the tube
Gas supply system 25 for operation under non-flammable process gases with a gas-tight rotating outlet
Gas supply package 4 for hydrogen operation
Vacuum package for evacuating the working tube, depending on the pump used up to 10⁻² mbar
Left/right tilting device for easier loading and unloading of the work tube
- For filling, the furnace is tilted to the right to convey the batch into the furnace. After the heat treatment, the furnace is swiveled to the opposite side for emptying, in order to convey the product out of the reactor again. It is not necessary to remove the reactor.
- Mixing reactor made of quartz glass with integrated blade for better mixing of the batch, closed on one side, large opening on the opposite side
- Rotary tube furnace assembled on base with integrated switchgear and controller, incl. transport casters
Process control and documentation via VCD software package for monitoring, documentation and control
