5. Operation and Configuration
5.2.6 Adjustable parameters in the IRT menu
With the Infrared Technology active, the temperature measurement during the closing or predrying process is conducted
directly on the surface of the object placed in the furnace. The furnace regulates the closing and predrying process on the
basis of the measuring data provided by the infrared camera.
Gentle drying and heating of the object is achieved by heating the heating muffle and by the furnace head movement
(furnace head opens and closes depending on the given situation).
There are different operating modes available for the IRT function, which can be selected using the [IRT] button.
IRT
IRT is the preferred and recommended operating mode for conventional veneering and all-ceramic firing
cycles.
If the operating mode "IRT" is selected, the infrared camera controls the predrying and closing processes
in such a way that the processes are conducted as quickly and efficiently as possible. The time-savings
compared to conventional predrying and closing processes are up to 20%.
IRT Plus
If the operating mode "IRT Plus" is selected, the infrared camera controls the predrying and closing
processes with a reduced drying rate. The closing and predrying processes are thus prolonged.
The operating mode IRT Plus is recommended for opaquer firing cycles and massive restorations.
IRT Off
If the operating mode "IRT Off" is selected, the infrared camera is deactivated. Closing and predrying
processes are conducted in the conventional manner, e.g. by entering a closing time.
IRT2 function after firing
After the firing process, the IRT2 function measures the surface temperature of the fired objects while the
furnace head is opening. The thermal image is shown on the screen and a notification on the display indi-
cates when the objects have reached the ideal temperature to be removed from the furnace.
The IRT2 function is only available in combination with the IRT function. The IRT2 function can be switched
on/off in the Settings menu.
