    Enables linear cooling
    The ingenious software and the firing chamber design enable a linear cooling process when in TTC mode: this prevents chipping, micro-fractures and cracks in zirconia ceramics.
    * Available only in the VARIO 200ZR version.

    The Vario 200 series ceramic ovens feature a firing chamber with an inner diameter of 120mm and heating coil height of approx. 60mm. This unique size configuration allows for temperature homogeneity across the entire firing tray unattained until now. This new configuration in conjunction with Zubler's legendary temperature control systems, guarantee the utmost precision and highest quality firings no matter where on the tray you put your work!

    The firing of dental ceramics on zirconia sub-structures carries a high risk of crack formation while cooling. With the VARIO 200ZR the new TTC technology is at your disposal. When engaged, this feature controls the rate of temperature descent, linearly dropping the temperature by a user defined degree per minute to evenly cool the objects and avoid sudden changes in temperatures. This feature allows for cool rates between 5 °C/min and 45 °C/min. Thanks to the innovative design of the firing chamber and intelligent software, the actively controlled temperature descent of the ceramic below the temperature of transition is ensured. This process will help keep the occurrence of chipping, cracking and micro-fractures to a minimum.

    Z-120 Technology

    There is a considerable difference between the available and usable space inside a ceramic oven. The available space is generally considered to be the diameter of the firing tray plus the working height. The usable space, conversely, includes the thermal conditions of a firing chamber.

    The heating coils used in ceramic ovens radiate at temperatures far above 1000°C during the sintering phase. Consequently, temperatures in direct proximity to the heating coil are ‘useless’ for consistent results when processing dental ceramics.

    Zubler is the only ceramic oven manufacturer in the world to address this problem and develop a firing chamber with a larger inner diameter. The VARIO 200 series ceramic oven’s 120mm inside diameter ensures temperature homogeneity across the entire 80mm-diameter firing tray, irrespective of the position or number of objects.

    Z-Dry Mode

    For optimal pre-drying, to avoid cracks and blisters, it is best to pre-dry at a constant temperature of 130°C. Utilizing the symmetrical lift design, chamber temperature and lift position, the VARIO 200/200ZR maintains the optimal pre-dry temperature. By reading the chamber temperature, the VARIO 200/200ZR will adjust the lift to compensate for any changes in the radiant temperature. The advantages:
     Cracks or blisters are prevented by controlled drying with the
    Z-Dry Mode.

     In subsequent firings you save wait-time thanks to the Z-Dry Mode. The work can be placed on the firing tray well before the programmed start temperature has been attained.
