Rotary Tube Furnaces for Batch Operation up to 1100 °C

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)
