High-Temperature Furnace with SiC Rod Heating for Sintering Zirconia up to 1550 ยฐC

Designed as a table-top model with SiC heating rods, this comparably inexpensive hightemperature furnace offers numerous advantages when sintering non-translucent zirconia with
an operating temperature of up to 1500 ยฐC. Compared to other models, however, the costs for
changing the heating elements are higher.The large 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.

ย„ Tmax 1550 ยฐC
ย„ Working temperature 1500 ยฐC, increased wear and tear must be expected in case of working at higher
temperatures
ย„ Single-phase connection (LHTCT 01/16)
ย„ Dual shell housing made of textured stainless steel sheets with additional fan cooling for low surface temperature
ย„ Only fiber materials are used which are not classified as carcinogenic according to TRGS 905, class 1 or 2
ย„ Scope of delivery includes a starter set for charging on one level, additional levels as additional equipment
ย„ Adjustable air inlet
ย„ Type S thermocouple
ย„ Controller C450, freely programmable
ย„ Switching system with solid-state-relays, power tuned to the SiC rods
ย„ Easy replacement of heating rods
ย„ Defined application within the constraints of the operating instructions
ย„ NTLog Basic for Nabertherm controller: recording of process data with USB-flash drive
ย„ Controls description see page 22
