1.2. GENERAL PURPOSE
The heating function is provided by means of the stainless heater placed inside the sterilization
chamber. The sterilization cycle consists of the water filling, heating, sterilization, steam discharge and
drying phases.
Water filling:
Distilled water is taken from the distilled water tank and pumped into the sterilization
chamber by means of a vacuum pump.
Heating:
The distilled water in the sterilization chamber is heated to generate steam at the required
temperature and pressure. During heating, the condense solenoid valve is opened and discharges the
unsaturated steam periodically.
Sterilization:
When the sterilization chamber temperature reaches the set temperature sterilization
starts. The sterilization chamber is kept at the required temperature and pressure during the set time.
During sterilization, the condense solenoid valve keeps the pressure in the chamber constant
according to the set temperature.
Steam discharge and drying (OT 020):
During the steam discharge phase, the steam in the
sterilization chamber is discharged and after the pressure has dropped to zero, moisture in the
sterilizator chamber is discharged according to driying time set on the OT 020.
Steam discharge and drying (OT 020V):
During the steam discharge phase, the steam in the
sterilization chamber is discharged and after the pressure has dropped to zero, the vacuum pump is
operated for drying. During drying, the air intake is ensured by opening the air intake solenoid valve
and taking in fresh air after it has been passed through 0,2
µ
m biological filter.
