The device typically supports up to 50 individual firing programs , allowing technicians to store custom protocols for different ceramic materials. Operational Features

Then, the cooling cycle. It was agonizingly slow, but necessary. Rapid cooling would introduce stress fractures. The Vacumat beeped softly, signaling the end of the program, but kept the door locked until the safe opening temperature was reached.
Press the key to loop through target values like firing time, temperature, and vacuum duration. Use the numerical block keys to adjust the target values for your specific porcelain or alloy parameters. Press the SET key to lock in the parameters to the desired program number. 3.

Users can set pre-drying times, pre-drying temperatures, rise times, and vacuum firing times (up to 20 minutes for each phase). Safety Features:
Clean the firing tray lift guide rails with a dry, lint-free cloth to ensure smooth upward and downward travel. Do not use liquid lubricants on the exposed rod.
Elias watched the vacuum indicator. This was the moment of truth. The Vacumat 50 engaged its vacuum pump, sucking the air out of the chamber. This pressure differential forced the porcelain particles to fuse densely, eliminating porosity. It was the difference between a dull, lifeless tooth and one that mimicked the vitality of natural enamel. The device typically supports up to 50 individual
Pressing "Start" raises the lift into the firing chamber to begin the cycle. Maintenance & Support
Input the updated firing temperature, ramp rate, or hold duration via the numerical block.
: The external vacuum pump is critical for vacuum firings. If the furnace fails to pull a vacuum, users are instructed to first check the pump and its connections independently from the furnace. If the pump is functioning correctly, then the vacuum system of the furnace itself should be inspected for leaks or blockages. Rapid cooling would introduce stress fractures
Dual high-contrast LCDs provide dedicated telemetry for program selections, chamber temperatures, remaining step times, and real-time vacuum depth.
While newer models like the VITA VACUMAT 6000 M have largely superseded it in modern labs, the Vacumat 50 is known for its:
Approximately 19 kg (excluding the optional vacuum pump). Firing Chamber: 96 mm diameter and 70 mm height. Max Temperature: 1,200°C. Power Consumption: Maximum of 1.5 kW. Programs: Features 50 custom firing programs. Operational Features
: A specialized "Slow Cool" feature that activates a controlled cooling phase once a firing cycle is complete to prevent thermal shock to the ceramic.
