Introduction : National Horizontal Rectangular Autoclave is based on the principle that microbiological action of saturated steam at elevated temp is rapid and thorough. All models work on downward displacement of air principle which is most economical method of obtaining for all types of bulk sterilization which are commonly needed in Medical, Agricultural, Research Institute, Pharmaceutical. Suitable for sterilizing hospital dressings, rubber plastic goods, surgical instruments, glass wares etc.
Boiler (Steam Generator) : Made of thick stainless steel plate suitably located under the sterilizer. High grade flanged type heating elements are fitted from front side for easy replacement/repair. Fitted with water gauge glass for water level, safety valve, water inlet and drain valves. It is also provided with low water level cut off device. This device protects the heater in the generator from burning out dry. The steam pressure in the boiler can be seen an individual pressure gauge.
Construction : Robust and rugged all weld construction which is leak proof unlike riveted construction. Inner chamber is made of thick plate of Mild Steel of nonmagnetic stainless steel of 304/316 quality and jacket is made out of rolled steel. Sterilizers will have single door made out of rolled steel lined with S. S. 304 sheet on both sides. All the sterilizers are 2 hydraulically tested to withstand 2.5kg/cm the working pressure. The steam jacket is lined on the outer side with high quality heat resistance materials to prevent heat losses due to radiation and is covered by SS 304 Sheet.
Doors Safety Lock : Every National Horizontal Rectangular Autoclave is fitted with Self Locking Safety Door which cannot be opened when the chamber is under pressure. The clutch mechanism automatically disengages the threads of the radial locking system for precluding any eventuality of accident when the chamber is under pressure. A heat resistant Neoprene Rubber gasket ensures zero leaks of the steam.
Pressure Control : Electrically operated “PIEZOSTAT” (Pressure Control Device) is incorporated in all electrically operated sterilizers. It economies power consumption and limits the use of release valve which would frequently blow steam into the room. It cuts off the power supply to heaters when the set pressure is achieved and re-energies heaters when pressure falls below the require limit/tap.
Sterilization : Complete sterilizing cycle is controlled from one point with the help of “Multi port valve” fitted at front top. Two speeds of exhaust are available for evacuating.
The Chamber : Two separate valves provided for evacuating air and steam from inner chamber and jacket as and when desired. A steam trap is fitted in the chamber discharge line to eliminate the condensate automatically.
Control Panel Switch Box :

• Electrical control panel box is mounted on the stand of the sterilizer for easy operation of the unit.
• Electrical parts – pressure switch, contactor, water level relay, MCB, RYB Indicators, & on off switch.

Other Features :

• Triple Safety - The sterilizer is provided with triple safety.
  
  • Pressure control switch which automatically cuts off the pressure at once required set value is achieved.
  • Two spring loaded safety valves are provided one at chamber and another at boiler level.
  • A dead weight safety valve at chamber level.

• A Plug Screen prevents the discharge line from choking. The plug is easily removable for routing cleaning.
• A powerful Ejector (for drying sterilized linen) circulates air through the chamber.
• The circulating air passes through a corrosion resistant metal wool filter.
• A Dial thermometer is provided to show the chamber temperature.
• Automatic Vacuum Breaker is provided to break vacuum in case of vacuum formation due to steam condensation.

Automatic Process Control Unit :

• The control unit is based on advance HMI With PLC controller or Microprocessor technology. This unit control different sterilization cycles with the help of in -built different program combinations.
• Unit has facility to operate in manual mode also.

Operating Temperature and pressure :
