Designed as table-top models with silicon carbide heating rods, these furnaces offer a variety of advantages when sintering Zirconia units. The large heating chamber, fast heat-up ramps and the apparent lack of chemical interactivity between zirconia and silicon carbide heating elements make these models the right choice for CAD/CAM manufacturing of zirconia restorations. The controller can be programmed for the individual zirconia material. The furnace is available in three different sizes. The 1 liter model can even be connected to the single phase power supply.

• Tmax 1400 °C, 1500 °C, or 1600 °C
• High-quality fibre materials, selected for the working temperature
• Housing made of sheets of textured stainless steel
• Double-walled housing for low external temperatures and high stability
• Typical cycle time for zirconia firing at 1500 °C approx. 8 hours including cooling down
• Optional flap door (HTC) which can be used as work platform or lift door (HTCT) with hot surface facing away from the operator
• Adjustable air intake opening in the furnace door, exhaust air opening in the back wall
• 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
• Spacer recommended to be placed under the bottom saggar for better temperature uniformity
• Manual or automatic gas supply system
