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. A controlled heating to the temperature profiles is also possible.

Standard Equipment:

• Tmax 1100 °C
• Single-zoned design
• Thermocouple type N
• 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
• Controller B510 (5 prgrams with each 4 segments), alternative controllers available

• 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 package 25 for operation under non-flammable protective or reaction gases with a gas-tight rotating outlet
• Gas supply packages 3 or 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

*This is designed to be a representation of the features available for this range. For more technical information and information on additional equipment please consult the brochure and reach out for a quote. This furnace features no safety technology for processes which produce combustible mixtures, for example debinding. If the furnace is still used for such processes despite this fact, the concentration of organic gas mixtures in the furnace must never exceed 3% of the lower explosion limit (LEL). This pre-requisite applies not only to normal operation but, in particular, to exceptional situations such as process disruptions (caused, for example, by the failure of a power unit). You must ensure that the furnace is adequately ventilated and vented. *
