Nabertherm Muffle Furnace LT Series with Brick Insulation, Flap Door

Muffle Furnaces with Brick Insulation up to 1300 °C

Heating elements on support tubes radiating freely into the furnace chamber provide for particularly short heating times for these muffle furnaces. Thanks to their robust, lightweight refractory brick insulation, they can reach a maximum working temperature of 1300 °C. These muffle furnaces thus represent an interesting alternative to the familiar L(T) ../12 models, when you need a higher application temperature.

Standard Equipment

• Heating from two sides
• Heating elements on support tubes ensure free heat radiation and a long service life
• Multi-layer insulation with robust, lightweight refractory bricks in the furnace chamber
