Our top-loading furnaces are perfectly suited for the heat treatment of longer or heavier components. The furnace is usually charged with a factory crane. Due to their high-performance air circulation, the furnaces provide for excellent temperature uniformity up to a maximum temperature of 850 °C. The top-loading furnaces for the temperature range up to 1280 °C  provide for very good temperature uniformity due to their five-side heating. Alternatively, these furnaces can also be provided with gas heating. Customized dimensions are designed and produced to accomodate the size and weight of the components to be treated. 

• Tmax up to 850 °C for furnaces with air circulation
• Tmax up to 1280 °C for furnaces with radiation heating
• Electrically heated or gas-fired
• Heating from both long sides for furnaces with air circulation
• Heating from all four sides and the bottom with SiC plates in the bottom as level stacking support for models to 900 °C or 1280 °C
• Depending on the furnace model, manual or electrohydraulic opening system of the lid with two-hand operation
• Closable air supply vents in the lower area of the furnace chamber
• Closable exhaust air flaps in the lid
• Over-temperature limiter with adjustable cutout temperature as temperature limiter to protect the furnace and load
• Exclusive use of insulation materials without categorization according to EC Regulation No 1272/2008 (CLP). This explicitly means that alumino silicate wool, also known as “refractory ceramic fiber” (RCF), which is classified and possibly carcinogenic, is not used.
• Defined application within the constraints of the operating instructions
• Controller with touch operation C540 (10 programs with each 20 segments)
• NTLog Basic for Nabertherm controller: recording of process data with USB-flash drive
• Freeware NTEdit for convenient program input via Excel^TM for Windows^TM on the PC
• Freeware NTGraph for evaluation and documention of firings using Excel^TM for Windows^TM on the PC
• MyNabertherm App for online monitoring of the firing on mobile devices for free download

• ADDITIONAL EQUIPMENT

• Motor-driven exhaust air flaps for faster cooling
• Controlled fan cooling with motor-driven exhaust air flaps
• Multi-zone control of the heating provides for optimum temperature uniformity
• Furnace chamber can be devided in length for short workparts, partitions can be controlled separately
• Designed for Tmax 950 °C, fan blade driven indirectly via a belt to protect the air recirculation motor against over-heating
• Process control and documentation via VCD software package for monitoring, documentation and control
