FUNCTIONING EN
4.6. 2nd PRESSURE RISE
This phase is similar to the 1
st
PRESSURE RISE and brings the pressure from the negative value reached during
vacuum pulse to 1.00 bar.
The sequence of vacuum pulses and pressure rises eliminates almost totally the residual air from the sterilization
chamber, which is also discharged from any hollow bodies or porous materials belonging to the load.
The elimination of air will allow for an optimal diffusion of steam, ensuring the same temperature in all the areas of
the load.
