The doors have also been designed in the same way as the chambers, so as to eliminate critical
stress points and ensure maximum operator safety and minimum maintenance.
The tightness of the pressure vessel is ensured by a special gasket patented by Fedegari in 1982,
which is seated in a groove milled into the chamber frame and is pressed by compressed air against
the door. This gasket requires no vacuum for door opening.
Two door types are available: automatic sliding doors and semiautomatic hinged doors.
Sliding doors move vertically in smaller machines and horizontally in all the larger models.
Hinged doors use the same construction model as sliding doors, but the opening motion is divided into
two separate steps: a translational motion at 45° (automatic) and a rotation (manual).
These solutions offer maximum flexibility and allow adaptation of the sterilizer to any installation
constraint or preference.
All doors are equipped with various safety devices and mechanical, pneumatic and process interlocks,
so as to prevent opening in condition which could cause danger for the operator and loss of tightness
of the gasket in cases of power or pneumatic blackouts.
