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
Scope of delivery includes a starter set for charging on one level, additional levels as additional equipment
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 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
Square saggar for charging of up to two layers (15 single crowns)
Lid for top saggar
Process control and documentation via VCD software package for monitoring, documentation and control
