These burnout furnaces are the perfect choice for daily work in the dental laboratory. These furnaces stand for excellent workmanship, advanced, attractive design and highest level of reliability. They are perfectly suitable for burnout of muffles and also for speed investments. These furnaces come equipped with either a flap door or lift door at no extra charge. The burnout furnaces come with a fiber insulation for 1100 °C or 1200 °C.
- Tmax 1100 °C or 1200 °C
- Dual shell housing made of textured stainless steel sheets with additional fan cooling for low surface temperature
- Heating from two sides by ceramic heating plates provides for an optimal temperature uniformity
- Thermocouple type N (1100 °C) or type S (1200 °C)
- Ceramic heating plates with integral heating element which is safeguarded against fumes and splashing, and easy to replace
- Exclusive use of insulation materials without categorization according to EC Regulation No 1272/2008 (CLP). This explicitly means that alumino silicate wool, also known as “refractory ceramic fiber” (RCF), which is classified and possibly carcinogenic, is not used.
- 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
- Solid state relays provide for low-noise operation
- Controller with touch operation B510 (5 programs with each 4 segments) resp. controller R7 for L 1/12 (adjustable for one temperature)
- MyNabertherm App for online monitoring of the firing on mobile devices for free download
- Freeware NTEdit for convenient program input via MS Excel on the PC
- Freeware NTGraph for evaluation and documention of firings using MS Excel on the PC
- NTLog Basic for Nabertherm controller: recording of process data with USB-flash drive
- Defined application within the constraints of the operating instructions
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 furnace 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
- 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
- Process control and documentation via VCD software package for monitoring, documentation and control
