Compact Tube Furnaces up to 1300 °C

The Nabertherm R Series Tube Furnaces are universal, “Made in Germany” furnaces for a wide variety of laboratory processes. They are defined by their excellent price-to-performance ratio, high-quality RCF-free insulation, and a robust dual-shell stainless steel housing for low surface temperatures.

Unlike basic models, these furnaces feature **heating elements on support tubes**. This allows the elements to **radiate heat freely** and directly onto the working tube, resulting in excellent temperature uniformity and a long service life. This series is available in 1200 °C or 1300 °C versions and a wide range of tube diameters and heated lengths.

Standard Equipment:

• “Made in Germany” Quality: Engineered for universal laboratory use.
• Max Temperature: Available as 1200 °C (Type N thermocouple) or 1300 °C (Type S thermocouple) models.
• Advanced Heating: Heating elements are mounted on support tubes for free heat radiation.
• Standard Working Tube: Includes a C 530 ceramic working tube and two fiber plugs for operation in air.
• Wide Size Range: Available with outer tube diameters from 50 mm to 170 mm and heated lengths from 250 mm to 1000 mm.
• RCF-Free Insulation: Exclusive use of high-quality insulation materials without categorization (non-carcinogenic).
• Durable Housing: Dual-shell ventilated housing made of textured stainless steel sheets.
• Advanced Controller: Standard B510 controller (5 programs, 4 segments) with a clear touch-screen display.
• Quiet Operation: Uses solid-state relays for low-noise heating.
• Data Recording: Includes NTLog Basic for recording process data via a USB flash drive.

Customize your Nabertherm R Series tube furnace with advanced options for process control, temperature uniformity, and atmosphere control.

Available Options & Accessories:

• Three-Zoned Design: For models with a heated length of 500 mm or more, a three-zoned design is available to significantly optimize temperature uniformity.
• Over-Temperature Limiter: A critical safety feature (thermal protection class 2) with an adjustable cutout temperature to protect the furnace and your valuable load.
• Charge Control: Allows for temperature measurement directly within the working tube (requires a temperature sensor port).
• Gas Supply Systems: A wide range of gas supply systems (1, 15, 2, or 4) are available for operating with non-flammable protective or reactive gases.
• Process Control Software: Integrate your furnace with the powerful VCD software package for comprehensive, PC-based process control, monitoring, and documentation.
