Predrying temperature Stage 2 (only available if Infrared Technology "OFF")
Predrying for Stage 2 is only available if Stage 1 has also been activated. The parameters are set in the
same way. At this stage, the furnace head is half open.
Value range °C: OFF or 100 – 700 °C; Value range °F: OFF or 212 1292 °F
Predrying holding time Stage 2 (only available if Infrared Technology "OFF")
This parameter defines the duration of the predrying process for Stage 2 once the desired predrying
temperature has been reached.
Value range OFF or 00:00 – 60:00 (mm:ss)
Thermo Shock Protection (TSP) (only available if Infrared Technology "OFF")
The TSP function protects the dental-lab work during the closing process. For this purpose, the TSP function
gauges the temperature of the firing chamber in the furnace head upon the start of the firing program. If
required, the closing path within the set closing time S is adjusted.
Setting options: On / Off
Pre-vacuum
If a firing program with pre-vacuum is conducted, the vacuum pump is switched on at the end of the
closing time (as soon as the furnace head is closed) and runs until the pre-vacuum time has elapsed. The
heating phase begins after the pre-vacuum time is over.
The value V1 is ignored upon the start of a program with individually activated pre-vacuum. The vacuum is
maintained until V2 is reached. V2 must be higher than the stand-by temperature B.
Setting options: OFF or 01:00 – 05:00 (mm:ss)
Hv Vacuum holding time
With this function, the vacuum share of the holding time can be individually set.
Example: H (Holding time) = 02:00 (mm:ss). If a vacuum share of 50% is desired, the parameter "Vacuum
holding time (Hv)" has to be set to 01:00 (mm:ss).
Setting options: OFF or 00:01 – 60:00 (mm:ss)
Quick opening of the furnace head
If the option "Quick opening of the furnace head" is activated, the furnace head opens at maximum
speed at the end of the holding time.
Setting options: On / Off
Extraction system
If this function is activated, any vapours are extracted during the closing process by means of the vacuum
pump, and fresh air is sucked in for a better firing and drying result.
Setting options: On / Off
