High-temperature Tube Furnaces RHTH/RHTV series
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 fibre plates enable energy-saving operation and a fast heating time due to low heat storage and heat conductivity. By using different gas supply systems, operations can be performed under a protective gas atmosphere, vacuum, or even with flammable gasses.
Dimensions without tube.
Option:
- Tmax 1600 °C, 1700 °C or 1800 °C
- MoSi2 heating elements, mounted vertically for easy replacement
- Insulation with vacuum-formed ceramic fibre plates
- Rectangular outer housing with slots for convection cooling
- Models RHTV with hinges for wall mounting
- Housing made of sheets of textured stainless steel
- Ceramic working tube made of material C 799 incl. fibre plugs operation under air
- Type B thermocouple
- Switchgear separate from furnace in separate floor standing cabinet
- Switchgear with control unit
- Possible controller variants are the programmable B 500, C 550 and P 570 (threes) with adjustable ramps and hold times.
- Over-temperature limit controller with manual reset for thermal protection class 2 in accordance with EN 60519-2 as temperature limiter to protect the oven and load
- Insulation only made of materials that are classified as not carcinogenic acc. to TRGS 905, class 1 or 2
- Standard power supply 400 V 3/N/PE 50/60 Hz
Dimensions without tube.
Option:
- Charge control with temperature measurement in the working tube and in the oven chamber behind the tube
- Alternative working tubes designed for process requirements
- Display of inner tube temperature with additional thermocouple
- Gas-tight flanges for protective gas and vacuum operation
- Manual or automatic gas supply system
- Three- or five-zone control for optimization of temperature uniformity
- Check valve at gas outlet avoids intrusion of false air
