NEWZirkonofen Turbo 



   


ZIRKONOFEN TURBO - A NEW ERA BEGINS
  Driven by diligence, dedication and enthusiasm, we strive tirelessly to give our clients always and only the best. We are aware of their requirements and we know our ambitions. It is the union of these two aspects that leads us to the best results. We never overlook any detail, searching for new solutions with meticulous attention until the finest point is set – only then can we be truly proud of our product. Our constant search for perfection and innovation drives us day by day and we do not know what the word "rest" means. 
No challenge is too tough for us and we have proved it again. 		  



With the new Zirkonofen Turbo and its pre-set fast sintering programs for each kind of Zirkonzahn zirconia, it is now possibile to sinter smaller zirconia structures in about 75 minutes. This cuts processing time by 84% and reduces electric consumption by 81%: zirconia structures can be milled, sintered and veneered in 1 hour and 55 minutes only!





The sintering platform is controlled by an intelligent electronic system developed in-house. This system monitors the temperature curve of the sintering chamber and controls the platform during the cooling phase.
 
  If the sintering chamber does not cool down quickly enough, the platform moves automatically downwards, ensuring optimal cooling processes and perfect sintering results.
 


 

SINTERING PROGRAMS

The Zirkonofen Turbo includes a large number of pre-set programs that are perfectly matched to each kind of Zirkonzahn zirconia. This means that the heating, holding and cooling phases vary slightly depending on the material. In addition, the user can create personal sintering programs.
The Speed and Ultraspeed programs cannot be used for sintering dental unit with a wall thickness exceeding 4 mm. Therefore, when selecting the sintering speed, attention must be paid to the elements' wall thickness and weight.


 
Personalised programs according to
the following parameters:
 
Temperature range    Heating rate
     
Room temperature  – 300 °C   50 °C/min
300 °C – 1100 °C   120 °C/min
1100 °C – 1700 °C   60 °C/min
     
Temperature range    Cooling rate
     
1700 °C – 1200 °C   60 °C/min
1200 °C – 800 °C   40 °C/min
800 °C – Room temperature    30 °C/min
  SLOW PROGRAM – 12 H   heavy   ≥ 5 g per  unit
 
  STANDARD PROGRAM – 8 H   medium heavy    3-5 g per unit
 
  SPEED PROGRAM – 3.5 H   light   2-3 g per unit
 
  ULTRASPEED PROGRAM – 75 min   super light   ≤ 2 g per unit
 
   
 
  Shortest program  – 45 min
 
  Large number of pre-set programs
 
  Personalised sintering programs
 
 
The Zirkonofen Turbo is equipped with pre-set fast sintering programs perfectly adapted to each Zirkonzahn zirconia material. The smaller and thinner the structure to be sintered, the shorter the required sintering time. With this furnace, 4-unit bridges can now be sintered in approx. 75 minutes.






 

Baking Recovery

  With the new Baking Recovery function, unsatisfactory sintering results are nearly impossible! After a power failure, the intelligent software checks whether the sintering program can be regularly completed without compromising the result or whether the sintering process must be must be suspended. If the sintering program can be continued, the user can see on the screen in which phase of the program the interruption occurred. If the program cannot be completed, the software will inform the user.



 

CAPACITY

In the Zirkonofen Turbo, zirconia restorations can be sintered by means of special accessories, like the sintering trays and the ceramic plate. The sintering chamber can contain up to 3 sintering trays stacked on top of each other, which permit sintering up to 120 zirconia elements in one single process. If bridges are sintered with a sintering stabiliser, the ceramic plate must be used, which offers space for up to 3 full-arch bridges.
 
   
To avoid pressure marks on the zirconia elements during sintering, the elements must be placed on the sintering tray well apart from each other. For a deformation-free framework, the base of the sintering tray should be covered with sintering granules.   The sintering chamber contains up to 3 sintering trays stacked on top of each other. In this way, up to 120 zirconia elements can be sintered in one sintering process.   To prevent discolouration or contamination of zirconia structures during the sintering process, it is recommended to cover the bridges with a ceramic protection cover. The new ceramic protection cover, with its curved shape, guarantees optimal heat distribution.



 

TEMPERATURE CALIBRATION

Every Zirkonofen Turbo is optimally calibrated before delivery, in order to achieve the best sintering results right from the first usage. Thanks to the temperature calibration program, the user can check at any time the oven's temperature control accuracy of +/- 2 °C at a final temperature of 1600 °C. If necessary, values can be corrected directly in the software.
 
   
1. Place the temperature calibration ring without using firing supports on the sintering platform and start the temperature calibration program   2. Let the ring cool down to room temperature and measure the diameter with a micrometer screw   3. Compare the measured value with the reference table and enter the difference in the software. Perform a second temperature calibration to check the final sintering temperature
 


 
  To obtain the highest quality results with unchanged translucency, colour gradient or flexural strength values, it is essential to adapt the sintering program to the material and to the structure to be sintered.
If parameters are correct but the results are still unsatisfactory, a temperature calibration must be carried out.

 
 
 

Software

The software, developed in-house, has been re-designed especially for the Zirkonofen Turbo.
A wider range of languages is now available to the users. Via the Internet connection, they can download and install updates directly in the furnace, in order to always work with the latest functions and sintering programs. The software also permits creating individual sintering programs in addition to the pre-set ones and, based on the user behaviour, it recognises the most frequently used programs and saves them as favourites, for an easier selection when starting a new sintering cycle.
