Nabertherm LHTCT 03/16 Furnace

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

• 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
