Chamber furnace Systems N 7/H - N 17/HR with their low but deep furnace chamber are particularly suitable for smaller batches. The process in these furnaces can be carried out exactly as in the chamber furnace systems LH 15/12 - LH 60/12. 

• Tmax 1150 °C
• The recommended working temperature is max. 1100 °C. Higher wear and tear of the protective gas box has to be expected at higher working temperatures up to 1150 °C
• Deep furnace chamber with three-sides heating: from both side walls and bottom
• Heating elements on support tubes ensure free heat radiation and a long service life
• Bottom heating protected by heat-resistant SiC plate
• Dual shell housing made of textured stainless steel sheets with additional fan cooling for low surface temperature
• Multi-layer insulation with high-quality lightweight refractory bricks in the furnace chamber
• 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.
• Low energy consumption due to multi-layer insulation
• Chamber furnace systems N 7/H - N 17/HR are designed as tabletop models
• Protective gas boxes for inert gas atmosphere with additional thermocouple, type K
• Automatic gas supply system for flow rates of 4 l – 50 l/min
• Charge control for measuring the temperature directly at the load in the gas supply box
• Charging plate and annealing and hardening foils
• Controller with touch operation P570 (50 programs with each 40 segments)
• MyNabertherm App for online monitoring of the firing on mobile devices for free download
• Freeware NTEdit for convenient program input via MS Excel on the PC
• Freeware NTGraph for evaluation and documention of firings using MS Excel on the PC
• NTLog Basic for Nabertherm controller: recording of process data with USB-flash drive
• Defined application within the constraints of the operating instructions

Additional equipment

• Process control and documentation via VCD software package for monitoring, documentation and control
