The high-temperature tube furnaces are available in either horizontal (type RHTH) or vertical (type RHTV) designs. High-quality insulation materials made of vacuum-formed fiber plates enable energy-saving operation due to low heat storage and heat conductivity. By using different gas supply systems, operations can be performed under non-flammable or flammable protective or reactive gases or under vacuum.

Process Control and Documentation
As one of the world’s largest furnace manufacturers, Nabertherm has many years of experience in the design and manufacture of standardized and customer-specific control systems. All controls are characterized by a very high level of operating convenience and even the basic version has extensive basic functions. Depending on the requirements, the functions can be expanded and adapted to your needs. Professional software solutions for single or multiple furnace management as well as process and batch documentation based on our Nabertherm controllers complete the range.
Also for compliance with industry-specific standards that define process control and documentation, such as for example, the AMS 2750 F for aviation, the CQI-9 in the automotive industry or the FDA in the pharmaceutical industry we offer standardized solutions.
Additional Equipment
- Charge control with temperature measurement in the working tube
- Three-zone control for optimization of temperature uniformity (only horizontal tube furnaces RHTH)
- Gas supply system 2 for non-flammable protective or reactive gas operation
- Gas supply packages 3 or 4 for hydrogen operation
- Vacuum package to evacuate the working tube
- Process control and documentation via VCD software package for monitoring, documentation and control
