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.
-Tmax 1600°C, 1700°C or 1800°C
-MoSi2 heating elements, mounted vertically for easy replacement

-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 400, C 450 and P 480 (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


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
