FOD ovens, such as autoclaves, run batch processes and are the ideal
solution for the sterilization of all those production lines in which
the variability of products, batches and formats do not allow the use
of continuous sterilizers such as tunnels. FOD ovens main advantage
lies on its particle contamination class assurance. Fedegari
guarantees the contamination level to remain under the established
standards values for 100 class. This accuracy is verified also during
the most critical phases such as heating and cooling, when the thermal
expansion of the filters may release a great amount of particles.
Particulate contamination control originates from complex fluid
dynamic studies and a close collaboration with Camfil, the world’s
most respected filter manufacturer, with whom Fedegari works at the
development of high-temperature filters. DESIGN & TECHNICAL
FEATURES
• Sterilizing chamber: sealed welding, made of AISI 304 stainless
steel 1,5 mm thick.
• Single-leaf flush door on both sides, internal surface in AISI 304
stainless steel.
100 mm thick rock-wool panels guarantee perfect thermal insulation:
average temperature of 40 °C on the external surfaces at operating
temperature of 250 °C.
Electric heating through AISI 321 stainless steel heating elements,
I5753093 assembled on a sliding frame for easy removal and
maintenance.
• Cooling by AISI 304 stainless steel heat exchanger.
• Continuous automatic control and regulation of pressurization of
the sterilizing chamber.
• Continuous filtering of air in the sterilizing chamber, thanks to
a system composed by 4 HEPA filters.
• 5 RTD PT100 temperature probes.
• Safety thermometer on non sterile front to prevent door opening if
chamber temperature exceeds set value.
• Stainless steel port for validation probe positioned on not
sterile side.
