Vacuum Firing Furnace
Engineered for the modern prosthetic laboratory, this dental porcelain furnace delivers precise, repeatable ceramic firing across the full spectrum of fixed restorations — from feldspathic layering to lithium disilicate pressables.
A motorized platform automates tray positioning throughout every firing cycle, removing manual handling at the moments that matter most.
The high-purity quartz tube chamber, driven by a Kanthal A1 heating element and backed by a –97 kPa oilless vacuum pump, creates the clean, controlled environment your porcelain demands.
Whether you’re firing PFM copings, glazing full-contour zirconia, or sintering pressable ceramics, this vacuum porcelain furnace keeps every result consistent and every crown ready on time.
FEATURES
Vacuum System — fewer porosities, stronger bonds
- Integrated oilless pump reaches –97 kPa with multi-layer line filtration
- Stable, contamination-free evacuation throughout every cycle
- Deep vacuum + correct vacuum timing → reduced porosity and reliable porcelain-metal bonding on PFM crowns
Thermal Precision — correct shrinkage, no cracks
- ±1 °C accuracy via K-type thermocouple; no perceptible overshoot at the 920 °C optimal hold point
- Programmable ramp rates up to 150 °C/min and fully customisable soak times
- Precise temperature control + correct ramp/soak profiles → predictable ceramic shrinkage, accurate fit, and reduced cracking
Chamber & Throughput — consistent esthetics, higher output
- Ø 100 mm × 80 mm firing chamber sized for full arch cases and multiple-unit spans
- 100 stored programs covering glazing, crystallisation, and sintering — fully customisable
- Adequate chamber size + repeatable program recall → higher daily throughput with uniform esthetic outcomes
Energy-Efficient Construction
- BR-1430 high-purity ceramic fibre insulation (Japanese imported) cuts energy use 40% vs. conventional muffle designs and weighs 30% less
- Overnight standby hold at 300 °C draws only 10 W/h
Electrical Resilience Wide 94–264 V AC tolerance with anti-interference circuitry protects against mains fluctuations common in laboratory environments.
