These high-temperature furnaces are ideally suited for sintering bridges and crowns made of translucent zirconia. The special heating elements made of molybdenum disilicide promise very good protection against chemical interaction between the charge and the furnace components. The bridges and crowns are loaded in ceramic saggars. These high-temperature furnaces are particularly convincing due to their very good price-performance ratio. The furnaces can be individually programmed for all recommended sintering curves by almost all zirconium manufacturers.

Tmax 1650 °C
Furnace chamber with a volume of 1 or 4 liters
High-quality heating elements made of molybdenum disilicide offer very good protection against chemical interaction between charge and heating elements
Dual shell housing made of textured stainless steel sheets with additional fan cooling for low surface temperature
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.
Scope of delivery includes a starter set for charging on one level, additional levels as additional equipment
Adjustable air inlet
Furnace chamber can be charged with up to two (LHT 01/17D) or three (LHT 03/17D) saggars, 15 or 25 individual crowns per level (depending on model)
Exhaust air opening in the roof
Type S thermocouple
Precise temperature control, also in the lower temperature range for drying
Switchgear with steady control of the heating elements
Freely usable for sintering blanks of almost all leading manufacturers
Controller with touch operation P580 (50 programs with each 40 segments)
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

付加装置

Additional equipment

Over-temperature limiter with adjustable cutout temperature as temperature limiter to protect the furnace and load
Stackable saggars for loading in up to two or three levels, depending on model
Process control and documentation via VCD software package for monitoring, documentation and control
