This Vacuum Porcelain Furnace is a laboratory-grade ceramic firing unit engineered for the precise sintering and glazing of fixed prosthetic restorations.
Its motorized platform delivers fully automatic lift-and-lower tray positioning, eliminating manual handling during critical firing cycles.
The firing chamber employs a high-purity quartz tube construction paired with a premium Kanthal A1 resistance element, ensuring exceptional thermal uniformity throughout the working zone.
Temperature accuracy of ±1°C is maintained across a continuous working range up to 1,000°C, with a maximum ceiling of 1,200°C for advanced ceramic applications.
An integrated oilless vacuum pump delivers stable vacuum down to –97 kPa, keeping restorations free of contamination throughout the evacuation cycle.
Compatible with Vita In-Ceram, feldspathic and leucite-reinforced layering porcelains, lithium disilicate pressables, and all major ceramic systems routinely processed in a full-service prosthetic laboratory.
FEATURES
Maximum firing temperature of 1,200°C with a continuous working range up to 1,000°C, accommodating all low- to high-fusing dental ceramic systems.
High-precision K-type thermocouple maintains ±1°C temperature accuracy with no perceptible overshoot, ensuring repeatable and predictable firing outcomes.
Kanthal A1 resistance heating element fully enclosed within a quartz tube, preventing porcelain adhesion to the wire and extending element service life.
Colour LED touch screen panel with storage for 100 fully customisable firing programs, covering glazing, crystallisation, and sintering protocols.
Integrated oilless vacuum pump reaching –97 kPa; multi-layer vacuum line filtration protects internal components and ensures long-term system reliability.
BR-1430 high-purity ceramic fibre insulation reduces energy consumption by 40% vs. conventional muffle designs; overnight standby hold at 300°C draws only 10 W/h.
Wide voltage tolerance of 94–264 V AC with anti-interference circuitry, safeguarding the unit against instantaneous mains fluctuations common in laboratory environments.
