repeated steam entry and discharge, sucks the air out of the chamber and
introduces saturated steam into the chamber.
Depending on selected program and the current chamber temperature at
program start, additional
→fractionations follow.
Heating-up phase
The heating-up phase follows after the evacuation phase. A pressure
discharge with a corresponding display is carried out at the end of the
