NABERTHERM RSRB series Rotary Tube Furnaces for Batch Operation , up to 1100 °C

NABERTHERM – Rotary Tube Furnaces for Batch Operation up to 1100 °C

Introduction
The RSRB series rotary tube furnaces are developed and manufactured by Nabertherm GmbH, the original inventor of modern laboratory and industrial furnace technology. These furnaces are specifically designed for batch operation, where the rotation of the working tube ensures continuous motion of the charge. With their quartz reactor design featuring tapered pipe ends, batches can be retained inside the furnace for arbitrarily long heat-treatment periods, enabling precise and controlled heating according to defined temperature profiles.

Product Overview
The RSRB rotary tube furnaces are compact, table-top models that combine robust stainless steel construction, low-noise operation, and advanced process control. They are ideal for laboratories and industrial applications requiring reliable batch processing with excellent temperature uniformity and flexible operation.

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
• Insulation materials free from carcinogenic refractory ceramic fiber (RCF)
• Thermocouple type N
• Solid state relays for low-noise operation
• Heating elements on support tubes for free radiation
• Table-top design with quartz glass reactor (open on both sides, tapered ends)
• Reactor removable for emptying; beltless drive and hinged housing (<180 °C opening temperature) for easy removal
• Adjustable drive speed: approx. 1–40 rpm
• NTLog Basic for process data recording via USB
• Controller B510 with touch operation (5 programs, each with 4 segments)

Additional Equipment

• Charge control with temperature measurement inside the working tube
• Three-zone control for optimized temperature uniformity
• Quartz glass reactor open on both sides with knobs for improved charge mixing
• Gas supply system 25 for non-flammable process gases with gas-tight rotating outlet
• Gas supply package 4 for hydrogen operation
• Vacuum package for evacuating the working tube (up to 10⁻² mbar depending on pump)
• Left/right tilting device for easier loading and unloading without reactor removal
• Mixing reactor made of quartz glass with integrated blade for enhanced batch mixing
• Rotary tube furnace mounted on base with integrated switchgear and controller, including transport casters
• Process control and documentation via VCD software package
