High-Temperature Tube Furnaces with SiC Rod Heating up to 1600 °C
The Nabertherm High-Temperature Tube Furnace (RHTC Series) is a “Made in Germany” solution for processes up to 1600 °C. It features powerful **SiC rod heating** for excellent uniformity, active housing cooling, and comes standard with the advanced P580 controller.
The Nabertherm RHTC Series Tube Furnace is an inexpensive and highly efficient solution for high-temperature laboratory processes up to 1600 °C[cite: 3, 5]. This “Made in Germany” furnace is universally designed with standard mounting options, making it flexible for a wide range of applications, including those in the polymer and materials science industries.
Its superior performance comes from robust **SiC (Silicon Carbide) heating rods** arranged parallel to the working tube, which provide excellent temperature uniformity. The furnace also features **active cooling** and a dual-shell housing, which ensures low surface temperatures even when operating at 1600 °C. It comes standard with the advanced P580 controller for complex, multi-segment programming.
Standard Equipment:
- “Made in Germany” Quality: Engineered for high-temperature reliability.
- Max Temperature: 1600 °C (recommended working temperature 1500 °C for extended use).
- High-Performance Heating: SiC heating elements arranged parallel to the tube for excellent uniformity and easy replacement.
- Active Cooling: Actively cooled dual-shell housing made of textured stainless steel for low surface temperatures.
- High-Purity Work Tube: Includes a C 799 ceramic working tube and two fiber plugs for operation in air.
- RCF-Free Insulation: Exclusive use of high-quality insulation materials without categorization (non-carcinogenic).
- Precision Control: High-quality Type S thermocouple for accurate temperature measurement.
- Advanced Controller: Comes standard with the powerful **P580 controller** (50 programs, 40 segments each).
- Quiet Operation: Uses solid-state relays for low-noise heating.
- Data Recording: Includes NTLog Basic for recording process data via a USB flash drive.
Enhance the functionality of your Nabertherm RHTC high-temperature furnace with these optional accessories for process control and atmosphere control.
Available Options & Accessories:
- Over-Temperature Limiter: A critical safety feature (thermal protection class 2) with an adjustable cutout temperature to protect the furnace and your valuable load[cite: 4].
- Charge Control: Allows for temperature measurement directly within the working tube via a separate thermocouple[cite: 4].
- Gas Supply Systems: A range of manual or automatic gas supply systems (1, 2, or 4) are available for operation with non-flammable protective or reactive gases[cite: 4]. (Note: Tmax is 1500 °C with gas systems) .
- Process Control Software: Integrate your furnace with the powerful VCD software package for comprehensive, PC-based process control, monitoring, and documentation[cite: 4].
