2. Process-lock to prevent opening of the door after successful completion of the test cycle. 
3. Limit switch provision for door lock indication.  

Insulation 
The gap between the sterilization chamber and outer jacket will be heavily insulated with minimum of 50-mm thick R. B. Glass Wool material to avoid thermal leakage 


Vacuum Break Filter 
A 0.3-micron vacuum break Air filter is provided on the sterile side for pressure equalization after vacuum creation. 


Piping Package
All process piping in contact with the chamber will be fabricated from SS-304 grade material with argon welding. All connections and fittings used are sanitary tri-clamp with silicone seals. All non-contact piping will also be fabricated from SS-304 grade material with argon welding. All drain lines and exhausts systems are connected to a drain manifold. The pipelines will have a 2% slope for full draining to prevent contamination. All pneumatic lines will be of polyurethane material with aluminum die-cast connectors. 


Valve Package 
The process valves in contact with the chamber will be of SS-304 material with Teflon seat and tri-clamp connections. All non-contact valves will also be of SS-304 material with Teflon seat. All automatic valves will be pneumatically actuated angle valves. All the system valves will be actuated by instrument air controlled via solenoid valves. 


Steam Accessories 
The jacket and chamber are provided with an over pressure safety valve. The jacket is provided with a steam trap.


Surface Finish 
The inside surface of the chamber and doors are finished to a surface finish better than 0.8 Ra value. All other non-contact parts are polished to a surface finish better that 180 grit. 


Process Management System (In-built programs)
The sterilizer is designed to perform a wide range of test and production programs to meet the latest regulatory requirements. Following test cycles can be carried out during the operation

1. Gravity cycle (Slow exhaust cycle) - For sterilization of media in open containers
2. Component & Garment cycle
3. Chamber leak test cycle
4. Bowie & Dick test cycle

Temperature and pressure sensors 
Two TEMPERATURE SENSORS will be provided; one inside the chamber and one at drain outlet. Inputs/outputs of all sensors and electronic parts are monitored, processed and controlled by PLC and HMI for accurate data processing.  
A pressure transmitter is connected to the inside chamber. All utility lines to be provided with a pressure switches for generating an alarm in case of utility failure.
