Heat treatment tube furnace RSRB series

Product overview
The RSRB series rotary tube furnaces are designed for batch (discontinuous) heat-treatment processes. Rotation of the quartz working tube keeps the charge in motion while tapered tube ends retain the load for extended processing times. Controlled heating by programmable temperature profiles is available.

Standard equipment

• Maximum temperature up to 1100 °C
• Single-zone heating as standard
• Ventilated dual-shell housing in textured stainless steel for low external surface temperature and mechanical stability
• Insulation materials used are not classified under EC Regulation No. 1272/2008 (CLP); no alumino-silicate/RCF wool
• Thermocouple type N
• Solid-state relays for low-noise heater control
• Heating elements mounted on support tubes for free radiation
• Table-top configuration with quartz glass reactor open at both ends and tapered ends
• Removable reactor for emptying; beltless drive and hinged housing (opening temperature < 180 °C) for easy removal
• Infinitely adjustable drive approx. 1–40 rpm
• NTLog Basic for controller: process data recording via USB flash drive
• Touch controller B510 (5 programs × 4 segments)

Additional equipment

• Charge control with temperature measurement inside the working tube
• Three-zone control to optimize temperature uniformity
• Reactors with ribs/knobs or mixing variants for improved batch mixing
• Gas supply system 25 for non-flammable process gases with gas-tight rotary outlet
• Gas supply package 4 for hydrogen operation
• Vacuum package for evacuating the working tube (depending on pump, down to ca. 10⁻² mbar)
• Left/right tilting device for simplified loading/unloading (furnace tilts to convey charge in or out; reactor removal not necessary)
• Mixing reactor made of quartz glass with integrated blade for improved mixing
• Rotary tube furnace on base with integrated switchgear and controller, incl. transport casters
• Process control and documentation via VCD software package
