Saturated Steam Sterilizers

The high operating flexibility of these autoclaves arises from the intrinsic characteristics of the saturated-steam process, from the features of the auto¬clave's construction and from the process controller's flexibility.

Every sterilizer is equipped with a water-ring vacuum pump which operates during various steps of the process, such as:

• initial evacuation of the air by vacuum/steam pulses or by steam injection
• constant draining of the condensate from the chamber, according to the principle of "dynamic steam"
• treatments below 100°C
• final drying of the loads.

Another special feature - one which used to be opposed but is now adopted by other manufacturers as well - is the control of the sterilization stage according to a pressure signal, rather than temperature.

The flexibility of the sterilizers of the FOF series, once the suitable plant options have been selected, makes them suitable for a wide range of treatments, some of which are mentioned below:

• sterilizations of various solid materials.
• sterilizations of porous materials.
• sterilizations of filled ampoules with fast vacuum for tightness test.
• sterilizations of filled ampoules, vials or bottles with cooling by means of

D.I. water spray under counter-pressure of sterile air sterilizations as above, with cooling by means of:

• heat-sterilized and cooled D.l. water spray
• circulation of cold water in jacket with optional circulation of the air by magnetically driven fan(s).
