High-Temperature Sintering Furnaces up to 1550°C

Designed as a table-top model with SiC heating rods, this comparably inexpensive high-temperature furnace offers numerous advantages when sintering non-translucent zirconia with an operating temperature of up to 1500°C. The heating chamber and fast heat-up times make this model a good choice for CAD/CAM machining of zirconia. The controller of the furnace is freely programmable for the individual sintering of the zirconia material. The high-temperature furnace is also designed for connection to the single-phase power grid.

· Tmax 1550°C
· Working temperature 1500°C, increased wear and tear of heating elements must be expected in case of working at higher temperatures
· Single-phase connection (LHTCT 01/16)
· 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
· Furnace chamber can be charged with up to two (LHTCT 01/16) or four (LHTCT 03/16) saggars, 15 individual crowns per level
· Adjustable air inlet
· Type S thermocouple
· Switching system with solid-state-relays, power tuned to the SiC rods
· Easy replacement of heating rods
· Controller with touch operation C550 (10 programs with each 20 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 documentation 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
