3.1 Programs description
If vacuum pulse is determined '= 0' in any program by the operator, the program
can be used as a 'Gravity' program. A message 'Gravity' is displayed on the right
side of the screen.
Program 1 - for Unwrapped goods (Fast 250)
This program is intended for unwrapped rigid (like instruments) and other goods,
which its manufacturer declares their compliance to be sterilized in the following
conditions:
♦
Sterilization temperature 250ºF
♦
Sterilization time: 15 mins.
♦
Dry time: 10 mins.
Performance description:
Residual air is displaced due to 3 vacuum pulses (down to 25 kPa) and 2 steam
pulses up to 199 kPa. The third vacuum pulse is followed with introducing
saturated (controlled) steam into the chamber to the required sterilization
temperature.
Sterilization period is controlled in a way that the sterilization temperature will not
drop below the required temperature, neither will increase by more than 37.4ºF.
The saturated steam conditions are controlled in such a way that fluctuation of
pressure does not allow a drop below 1kPa, neither an increase of 3 kPa above
the high limit of the Ste. Temperature.
Fast exhaust stage is performed by discharging rapidly the pressure from the
chamber. When the pressure reaches a level of 115 kPa the ejector is activated
until a pressure drop to 25 kPa.
Pressure equilibration . To enable the door to be opened, air is introduced to the
chamber through a microbiological filter till the equilibration with atmospheric
pressure.
Note:
The temperature of the chamber must be below 230ºF and the pressure must
be below 115 kPa to enable the door to be opened.
