6.5 Program 5: Liquid A – Cooling (ELC – cooling models only)
For liquids when the manufacturer recommends autoclaving at
temperatures of 121ºC. for 15 minutes.
Nominal parameters default settings
Sterilization temperature:121C (250F).
Sterilization time: 15 minutes.
Operations sequence:
(PV, pre-vacuum model only) Air removal stage; four vacuum pulses
removes air by drawing the chamber down to 20kPa.
Water enters the chamber and is heated until pressure reaches 110 kPa
Heating by actuation of electrical heaters until the sterilization
temperature is reached.
Sterilization temperature is maintained constant during the sterilization
time.
Forced cooling to the required end temperature (approx. 85ºC), while
the pressure in the chamber remains the same as the sterilization
pressure, by supplying compressed air into the chamber. The forced
cooling shortens the cooling stage significantly.
Fast exhaust, the steam is exhausted out of the chamber at a fast rate
until pressure decreases to ambient pressure.
Note: (BH, bio-hazard model only) If the cycle fails, fast exhaust is
performed through the bio-hazard filter.
