Ashing furnaces with hinged or lifting door

Muffle furnaces Nabertherm LV 3/11 – LVT 15/11 are used especially for ashing in the laboratory. Due to a special system of air inflow and outflow, more than 6 times air changes per minute are achieved. In this case, the incoming air is preheated, which ensures a good temperature distribution inside the muffle furnace.

• Maximum temperature 1100 ° C;
• Heating the muffle furnace from both sides with ceramic burners;
• Ceramic heating plates with integrated heating element, splash and flue gas proof, easy to replace;
• High quality, high tenacity, vacuum formed fiber module;
• Muffle furnace body made of structured stainless steel sheets;
• Double wall muffle furnace body for low external temperatures and high stability;
• Muffle furnaces are available as an option with either a hinged door (L), which can be used as an additional loading and unloading area, or a lifting door (LT), with the hot side facing away from the operator;
• Low noise operation of the furnace heating system with semiconductor relays;
• More than 6 times air changes per minute;
• Adjustable intake air opening in the muffle furnace door;
• Good temperature distribution inside the muffle furnace due to the preheating of the incoming air.

Additional equipment for muffle furnaces:

• Adjustable temperature limiter with adjustable shutdown temperature for thermal protection class 2 according to EN 60519-2 as overheating protection for ovens and products.
