| Parameter | Value | |-----------|-------| | Dimensions (W x D x H) | 320 x 470 x 570 mm | | Chamber diameter x height | 90 x 75 mm | | Weight | 38 kg (approx. 84 lb) | | Power | 230 V / 50‑60 Hz, 1,800 W | | Fuse | 10 A (slow-blow) | | Cooling | Forced air (fan-assisted) |
The furnace utilizes a PtRh-Pt (Platinum Rhodium-Platinum) thermocouple housed within a ceramic protection tube. The temperature range spans from 0°C to 1600°C (optional up to 1650°C with specific firmware), with a heating rate adjustable from 1 to 99°C per minute. The stability is rated at ±1°C, ensuring that even multi-layer ceramics fire without distortion.
The VITA VACUMAT 50 UPD is the dental equivalent of a classic mechanical watch. It lacks the digital bells and whistles of modern furnaces, but it performs its core function—firing beautiful, bubble-free ceramic restorations—with exceptional reliability.

For the price-to-performance ratio, the VITA VACUMAT 50 UPD remains a gold standard for dental ceramic firing. By following the maintenance schedules and understanding its limitations, this furnace can deliver a decade or more of reliable service.
In the world of modern dentistry and dental technology, precision is not just a goal—it is a requirement. For dental technicians and lab owners, the firing process of ceramic restorations can make or break the final aesthetic result. Among the pantheon of dental furnaces, one model has consistently stood out for its reliability, German engineering, and technological longevity: the VITA VACUMAT 50 UPD. | Parameter | Value | |-----------|-------| | Dimensions
Whether you are troubleshooting an existing unit, looking to upgrade your lab’s equipment, or simply researching the best pressing and firing furnace on the secondary market, this guide covers everything you need to know about the VITA VACUMAT 50 UPD.
Rating: 8.7/10
Best for: Medium-to-large dental labs that need a reliable, precise, and fast furnace for veneers, crowns, bridges, and pressing ceramics.
Not for: Budget startups or labs that exclusively sinter high volumes of zirconia (dedicated sintering furnaces are more efficient for that).
The Vacumat 50 UPD is an updated version of Vita’s legendary Vacumat 40/50 line. It improves temperature uniformity, vacuum control, and user interface while keeping the robust build quality that made its predecessors industry staples. You should skip this model if:
| Problem | Likely Cause | Fix | |---------|--------------|-----| | Porcelain bubbles | Too high vacuum / too fast ramp | Reduce vacuum start temp, slow heating | | Underfired (glassy) | Too low final temp | Increase 10 °C | | Overfired (blurred anatomy) | Too high temp / long hold | Reduce temp or hold time | | Cracked restorations | Fast cooling / wet tray | Slow cool, dry tray before firing | | Vacuum error | Pump failure or door seal leak | Check seal, clean pump filter |
Before first use, or after moving the unit, run a calibration routine. Place a calibration ring or a sample ceramic disc on the stand. Access the "Service" menu and select "Calibrate Offset." The furnace will heat to 500°C to verify thermocouple accuracy.
Even the best furnaces have occasional hiccups. Here are issues specific to the VACUMAT 50 UPD.
