The Nabertherm L range of muffle furnaces have been proven for daily laboratory use. These models stand out for their excellent workmanship, advanced and attractive design, and high level of reliability. The muffle furnaces come equipped with either a flap door or lift door at no extra charge.
Standard Equipment:
Thermocouple type N (1100 °C) or type S (1200 °C)
Size ranges from 1L to 40L
Heating from two sides by ceramic heating plates (heating from three sides for muffle furnaces L 24/11 - LT 40/12) for an optimal temperature uniformity
Ceramic heating plates with integral heating element which is safeguarded and easy to replace
Optional flap door (L) which can be used as work platform or lift door (LT) with hot surface facing away from the operator
Adjustable air inlet integrated in door (see illustration)
Exhaust air outlet in rear wall of furnace
Controller B510 w(5 programs each with 4 segments), alternative controllers available
Additional Equipment:
Chimney, chimney with fan or catalytic converter (not for L 1 and L 15)
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 automatic gas supply system
Port for thermocouple in the rear wall or in the furnace door
Charging rack with closed or perforated trays for loading the furnace in two levels incl. holder for inserting/removing the trays up to a max. temperature of 800°C and a max. loading weight of 2 kg for the L(T) 9/11 respectively 3 kg for the L(T) 15/11
*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. *
