Working Principle of Dry Heat Sterilizer

Heating Cycle

The Vials placed in trays are washed in non-sterile room and loaded on the trolley.
The trolley is moved to the sterilizer on a transfer trolley. Temperature and Times are set on the Digital Controller. The Impeller mounted on the top circulates the hot air horizontally over the charge. The air is heated by elements mounted on the top. Fresh air enters the system through HEPA Filter Module. The system incorporates two doors, one opening into the sterile room and the other opening in the non-sterile room. Both the doors are pneumatically interlocked. The temperature profile during sterilization cycle is recorded on a circular chart recorder, validation of the system is provided by a six-point digital temperature scanner.

Cooling Cycle

After the time period required for sterilizing the batch has elapsed, the heating circuit shuts of the pneumatics damper (exhaust) opens and cooling operation commences.
