Nabertherm Muffle/Incineration Furnaces
For maximum working temperatures of up to 1300 °C, different furnace families are available, tailored to the requirements of the process in question. The LE 2/11 – LE 14/11 universal furnaces, due to their optimum price/performance ratio, can be considered our best-sellers in the muffle furnace arena. They can be universally used for maximum temperatures of up to 1100 °C, have attractive product features, like high-quality housings of stainless steel and continuously adjustable ventilation openings. Their innovative heating using quartz emitters guarantees very short heating times. During the development of this model series, the focus was on customers needing a compact furnace which might not be needed every day, and needs to be cost-effective but still powerful.
For daily use, the familiar models L 3/11 – LT 40/12 have proved themselves for many years. These solid "all-rounders" are available with furnace chambers between 3 and 40 liters for maximum temperatures of 1100 °C or 1200 °C. The user can select whether to use a furnace with a folding door (L models) which can serve as a shelf when loading, or with a lift door (LT models) which pivots the hot side backwards, away from the operator.
If a professional furnace is needed for incineration, then the LV 3/11 – LV 15/11 incineration furnaces especially developed for this process are recommended. These furnaces are constructed in such a way that an air exchange of up to 6 times the furnace volume per minute is ensured. These furnaces still satisfy the requirement that the temperature distribution should not be too badly affected despite continuous air exchange with flowing fresh air. This important property is achieved by first guiding the cold fresh air through the heater of the furnace so that it only enters the furnace chamber after preheating.
