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 - 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 including fibre plugs operation under air - Type B thermocouple - Power unit with low-voltage transformer and thyristor - 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
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 - Stand for vertical operation
