We particularly recommend the muffle furnace L 9/11/SKM for heat treatment of aggressive substances. The furnace has a ceramic muffle with embedded heating from four sides. The muffle furnace thus combines a very good temperature uniformity with excellent protection of the heating elements from aggressive atmospheres. Another aspect is the smooth, nearly particle free muffle (furnace door made of fiber insulation), an important quality feature.

Standard Equipment:

• Tmax 1100 °C
• Muffle heated from four sides
• Furnace chamber with embedded ceramic muffle, high resistance to aggressive gasses and vapours
• Optional flap door (L) which can be used as work platform or lift door (LT) with hot surface facing away from the operator
• Adjustable working air inlet in the door
• Exhaust air outlet in rear wall of furnace
• Controller B510 (5 programs with each 4 segments), alternative controllers available

Additional Equipment

• Chimney, chimney with fan or catalytic converter
• Over-temperature limiter with adjustable cutout temperature as temperature limiter to protect the oven and load
• Protective gas connection to purge with non-flammable protective or reaction gases (not available in combination with chimney, chimney with fan or catalytic converter) not gas tight
• Manual or automation gas supply system
• Port for thermocouple in the rear wall or in the furnace door

*This is designed to be a representation of the features available for this range. For more technical information and information on additional equipment please consult the brochure and reach out for a quote. This furnace features no safety technology for processes which produce combustible mixtures, for example debinding. If the furnace is still used for such processes despite this fact, the concentration of organic gas mixtures in the furnace must never exceed 3% of the lower explosion limit (LEL). This pre-requisite applies not only to normal operation but, in particular, to exceptional situations such as process disruptions (caused, for example, by the failure of a power unit). You must ensure that the furnace is adequately ventilated and vented. *
