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 °CMoSi2 heating elements, mounted vertically for easy replacementInsulation with vacuum-formed ceramic fibre platesRectangular outer housing with slots for convection coolingModels RHTV with hinges for wall mountingHousing made of sheets of textured stainless steelCeramic working tube made of material C 799 incl. fibre plugs operation under airType B thermocoupleSwitchgear separate from furnace in separate floor standing cabinetSwitchgear with control unitPossible 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 loadInsulation only made of materials that are classified as not carcinogenic acc. to TRGS 905, class 1 or 2Standard power supply 400 V 3/N/PE 50/60 HzDimensions without tube.Option:Charge control with temperature measurement in the working tube and in the oven chamber behind the tubeAlternative working tubes designed for process requirementsDisplay of inner tube temperature with additional thermocoupleGas-tight flanges for protective gas and vacuum operationManual or automatic gas supply systemThree- or five-zone control for optimization of temperature uniformityCheck valve at gas outlet avoids intrusion of false air

These compact tube furnaces are used when laboratory experiments must be performed horizontally, vertically, or at specific angles. The ability to configure the angle of tilt and the working height, and their compact design, also make these tube furnaces suitable for integration into existing process systems.Vertical or horizontal operation freely adjustableWorking height freely adjustableWorking tube made of C 530 ceramicControl system integrated in furnace baseNTLog Basic for Nabertherm controller: recording of process data with USB-flash driveEquipped with the programmable controller B 510 (with touch panel, 5 programmes with 4 segments each), optionally available with the C 550 controller (with touch panel, 10 programmes with 20 segments each)
