Furnace chamber with high-quality fiber materials and SiC heating rods on both sides of the furnace
Over-temperature limit controller
Designed as table model with SiC heating rods, these models offer numerous advantages when sintering zirconia. The large heating chamber and fast heating-up times make this model a good selection for the CAD/CAM processing of zirconia. The furnace controller can be freely programmed for the individual sintering of the zirconia material. The furnace is available in three different sizes. The model HTCT 01/16 is moreover designed for connection to the single-phase mains supply.
- Tmax 1600 °C
- Working temperature 1550 °C, increased wear and tear of heating elements must be expected in case of working at higher temperatures
- Model HTCT 01/16 with single phase connection
- High-quality fiber material, selected for the working temperature
- Housing made of sheets of textured stainless steel
- Dual shell housing for low external temperatures and high stability
- Optional flap door (HTC) which can be used as work platform or lift door (HTCT) with hot surface facing away from the operator (HTCT 01/16 only with lift door)
- Switching system with solid-state-relays, power tuned to the SiC rods
- Easy replacement of heating rods
Additional equipment
- Over-temperature limit controller with manual reset for thermal protection class 2 in accordance with EN 60519-2 as temperature limiter to protect the oven and load
- Square saggar for charging of up to three layers
- Lid for top saggar

Electrically driven lift-bottom
Saggar
Due to their maximum temperature of 1650 °C these models are perfectly suited for sintering of translucent zirconia. The electrically driven lift-bottom provides for easy charging. By using special heating elements made of molydenum disilicide crowns and bridges are protected against chemical contamination at the best. The charge will be placed in saggars made of technical ceramics. Up to three saggars on top of each other guarantee high productivity. Model LHT 02/17 LB Speed is additionally equipped with rapid cooling device. The table automatically opens stepwise for faster cooling. Depending on the charge and the type of saggars process times shorter than two hours can be realized.
- Tmax 1650 °C
- Special, high-quality heating elements made of molybdenum disilicide offer best possible protection against chemical interaction between charge and heating elements
- Furnace chamber lined with first-class, durable fiber materials
- Outstanding temperature uniformity due to all-round furnace chamber heating
- Furnace chamber with a volume of 2 liters, table with large footprint
- Electric screw drive with push button operation, automatic opening of Speed model for cooling possible
- Housing made of sheets of textured stainless steel
- Exhaust air vent in the roof
- Speed model with drying function. When starting the program the table will be driven in drying position and closes automatically at 500 °C
Additional equipment
- Over-temperature limit controller with manual reset for thermal protection class 2 in accordance with EN 60519-2 as temperature limiter to protect the furnace and load
- Square saggar for charging of up to three layers
- Process control and documentation with Controltherm MV software package
