Horizontal Cylindrical Autoclave

Introduction : National Horizontal Cylindrical Autoclave is based on the principle that microbiological action of saturated steam at elevated temperature is rapid and through. All models work on the principle of downward displacement of air which is the most economical method of obtaining sterilization. Robust and rigid construction, designed for all types of bulk sterilization which are commonly needed in Medical, Agricultural, research Institute and Pharmaceutical Industries. Suitable for Sterilizing hospital dressings, rubber, plastic goods, surgical instruments, glass wares, etc.

Construction : Triple walled with steam jacket and separate boiler Inner chamber and steam jacket are made up of Heavy gauge S.S. 316/304 Sheet with leak proof argon-arc welding. The sterilizer has single piece door made of stainless steel 316/304. Back plate and ring is also made of thick stainless steel sheet. All the sterilizers are hydraulically tested to with stand 2.5kg/cm2 times the working pressure. Mounted on tubular steel frame with ground leveling screwed flanges. The Outer jacket is wrapped with asbestos sheet or glass wool to minimize the heat losses due to radiation and is covered by polished stainless steel sheet for that elegant appearance.

Steam Generator : Made of heavy stainless steel sheet. Heavy ring mounted in front of the boiler with folding thick stainless steel plate is fitted with heating elements and low water level cutoff device to protect the former from burning out dry. Front folding plate system provides for easy cleaning of the deposited scale on the elements and the walls for long life and e efficiency. Fitted with water gauge glass for water level indication, water inlet and outlet valves.

Pressure Control  : The “PIEZOSTAT” (Pressure control device) is incorporated in all electrically operated sterilizers. I t economizes on power consumption and reduces the frequent opening of the steam release valve and thus prevents the release of steam in the room, It cuts off the power supply to heaters when the set pressure is achieved and reenergies the heating elements when pressure falls below the set point.

Heating Elements : Flanged type, immersion heating elements made of high grade materials having ISI certification.

Safety Door : Sterilizer has hinged self-locking single piece thick S.S. 316/304 plate door and cannot be opened when under pressure. The self-locking device automatically disengages the thread mechanism when the sterilizer is under pressure to preclude any eventuality of accident.

Single Point Control : Complete sterilizing cycle is controlled from one point with the help of “Multiport Valve” fitted at front top. Two speeds of steam exhaust are available; fast and slow. Easily readable jacket and chamber pressure on gauges mounted on the multi port valve. A moisture trap is fitted in the chamber discharge line to absorb the condensate automatically to prevent moistening of the subject matter to be sterilized.

Other Features :

• Triple Safety - The Sterilizer is provided with the triple safety features. At the boiler level by a PIEZOSTAT which automatically limits the pressure to the required set value and a spring loaded safety valve in case of its failure which releases the steam to keep pressure within the safety limits. At the chamber level, a spring loaded safety valve and a dead weight release valve to release the steam in case the pressure exceeds the safety limit. All these safety features function independent of one another and sequentially i.e. one take over the charge in case of other's failure.
• A plug screen prevents the discharge line from choking. The plug is easily removable for daily cleaning.
• Powerful Ejector for drying sterilized linen circulates air throughout the chamber. The circulating air passes through a corrosion resistant metallic wool filter.
• A dial thermometer is provided to show the chamber temperature.
• Automatic Vacuum breaker is provided to break vacuum in case of formation of vacuum due to steam condensation.
