Process:
Drying at 110 °C during a certain time with inlet- and outletvalves opened. Air intake is through the Hepa filter. After this time, sterilizing at 180 °C, c.q. required sterilizing temperature, or higher with all valves closed during a sterilizing time. Sterilizing begins when temperature in the objects has reached the required sterilization temperature. After this sterilizing time inlet and outletvalves, inlet- and outletair through Hepa-filters, opens to cool down. When the cooldown temperature of 50 °C has reached all the valves will be closed.
During the whole process, all the doors are locked. Only when the process has run through correctly after checking the temperature registration, the doors at the clean room side can be opened. The doors at the non clean room side remains locked. After removing the trolleys and closing the doors at the clean room side, the doors at the non clean room side opens. In case of failure the process will be shut down.
