Chamber furnace system N 41/H with gassing box The heating elements are mounted on support tubes. This ensures free heat radiation and a long service life.

Chamber furnace systems N 41/H with low but deep furnace chamber particularly suitable for small batches. The process in these ovens can be carried out in the same way.

-Tmax1150 °C -The recommended working temperature is max.1100 °C. At higher operating temperatures of up to 1150 °C, greater wear of the gassing box is to be expected. -Deep oven chamber with three-sided heating: from both side walls and from the floor -Heating elements on support tubes ensure free heat radiation and a long service life -Lower heater protected by heat-resistant SiC plate -Double-shell housing made of structured stainless steel sheet with additional fan cooling for low surface temperature -Multi-layer insulation with high-quality refractory lightweight bricks in the furnace chamber -Exclusive use of insulation materials without categorisation according to EC Regulation No. 1272/2008 (CLP). This means explicitly that no alumino-silicate wool, also called "refractory ceramic fibre" (RCF), is used, which is classified as carcinogenic and may be carcinogenic. -Exhaust air opening on the side of the furnace or on the rear wall of chamber furnace system N 31/H -Low energy consumption due to multi-layer insulation -Protective gas boxes for protective 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 consumer in the gas supply box -Charging plate and glow and hardening foils -Controller B500
