Interactive Graph Screen
Multi-stage program is interactively illustrated on the graph and the cycle’s elapsed time is visually indicated by color change.
Sky is the Limit – Unlimited choices of heating, cooling stages and holding durations provide a host of programming capabilities. The furnace is universally compatible to a wide variety zirconia.

The furnace can be remotely monitored and operated from PC, smartphone and tablets. Connectivity via Wifi (logo) links to our platform for connecting with devices for online operation and monitoring of the furnace. This connectivity also provides service applications such as online upgrades of software versions, program downloads and system diagnostics.


The Fast cycle
Fast cycles for maximum efficiency in minimum time.
SINTRA PRO/90zr tested and validated fast* 90 minutes with specific ZrO2 materials.
SINTRA PRO/120zrf is designed to deliver an Ultra-fast* cycle by 30%.
*Subject to the material being sintered, the sintering time can be relatively shortened.
