Cautions!
Both PT100 temperature sensors must be inside the bottles.
For proper sterilization, fill the bottles with approximately the
same amount of liquid.
Nominal parameters default settings
•
Sterilization temperature: 121
C (250
F).
•
Sterilization time: 15 minutes.
Operations sequence:
•
Heating:
Air enters the chamber followed by steam that heats it up
until the sterilization temperature is reached. Air adds pressure
needed to prevent swelling or warping of soft plastic items
.
Chamber
fan is used to mix air with steam.
•
Sterilization:
Sterilization is controlled in a way that the sterilization
pressure remains approx. 30% above the theoretical pressure
corresponding to the same temperature according to the steam table.
•
Cooling:
Forced cooling to the required end temperature, chamber
pressure remains at approx. 300 kPa and the cooling valve is opened.
•
Fast Exhaust:
The steam is exhausted out of the chamber at a fast
rate until pressure decreases to ambient pressure.
•
Drying:
N/A
•
Ending:
The system checks that End temperature and End pressure
have been reached, and then releases the door.
