Fedegari FOA

Autoclaves/Sterilizing Ovens/Freeze Dryers

The FOA air-steam steriliser from 2003 is suitable for:
- Sterilisation of parenteral solutions,
liquids in closed non-deformable containers (e.g. glass tubes)
and liquids in closed deformable containers
(e.g. plastic bags or bottles).
- Terminal sterilisation of pre-filled syringes.

The machine is designed to operate with the new RTWS3
temperature sensors, which,
especially in the large automatic loading models,
offer unparalleled ease of use and optimal process control:

It is equipped with fully automatic discharge/loading conveyors for maximum
productivity with virtually zero maintenance inside the sterilisation chamber.

Where the product is subject to separation or to accelerate
the thermal transition phases,
the entire load can be rotated throughout the process.

Steam-air FOA process:
Magnetically driven fans force a high rate of fluid circulation
within the chamber. Internal sanitary hollow plates
add additional heating/cooling capacity,
minimising the creation of condensation.

Steam and air are injected according to control algorithms
to finely control the process.
This system is the usual choice when terminally sterilised
products need to be dry-discharged.

Superheated water FOW process:
Water is continuously circulated through the system
and sprayed onto the load.
Fine control of heating and sterilisation is achieved
by superheating the water with modulated steam.
Cooling of the load is achieved by subsequent
cooling of the circulated water.
Back pressure control is in accordance with the steam-air mixing process.
The process is efficient and faster than the FOA process.
It is also an ideal process for processing at
