FURNACES ROHT
with exchangeable tubes
T max. 1700 °C and 1800 °C
- Tube diameter from 40 to 75 mm
- Heated lengths of 200 mm, 300 mm, 400 mm and 600 mm
- Designed for horizontal operation, vertical design on request realizable.
- Double-walled housing construction with forced rear ventilation, extremely low outside wall temperature
- Furnace insulation made of high-quality alumina material with very low thermal mass for rapid heating and cooling
- Very powerful heating via MoSi2 heating elements, with free heat radiation onto the tube and sample, high temperature accuracy and long service life of the heating elements.
- Furnaces are supplied as tabletop models with a tube made of
99.7 % Al2O3 as standard
- High-quality furnace housing, partly with lateral stainless steel cladding
- State-of-the-art switching and control technology via thyristors in phase-angle operation for very precise, wear-free and noiseless furnace control
- Switch and control system for horizontal furnaces mounted in the lower housing area
Highest temperatures
Tube furnaces with MoSi2 heating elements are designed for tem- peratures up to 1700 °C and 1800 °C. Tubes made of Alsint (C799) with inner diameters of 40, 50 and 75 mm are included in the scope of supply. Available in horizontal and vertical design. Horizontal fur- naces can also be supplied with multiple zones.
Additional Equipment
Tube furnaces can be adapted to the most varied conditions in the laboratory with the optional additional equipment and accessories, depending on the intended use:
- Controller with extended programming options
- Batch temperature measurement and control
- Adjustable over-temperature protection to protect furnace and load according to EN 60519-2
- Programming and data-logging software and interfaces
- Flanges for inert gas and/or vacuum operation as well as manual and automatic gas feed systems
- Vacuum pumps and cooling units
