Horizontal Cylindrical Steam Sterilizer

Introduction:
The sterilizer 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 and Pharmaceutical Institutions. The sterilizer is suitable for Sterilizing hospital dressings, linen, rubber, plastic goods, surgical instruments, glassware, utensils etc.

Construction:
The sterilizer is triple walled with steam jacket and separate boiler. The inner chamber and steam jacket are made up of Heavy gauge Stainless Steel sheet with leak proof argon welding.

The sterilizer has single piece door made of stainless steel plate. Back plate and ring is also made of thick stainless steel. All the sterilizers are hydraulically tested to withstand 2.5 times the working pressure.

The sterilizer is mounted on tubular steel frame with ground levelling screwed flanges. The Outer jacket is wrapped with glass wool to minimise the heat losses due to radiation and is covered by polished stainless steel sheet for that elegant appearance.

Steam Generator:
The steam generator is made of heavy stainless steel sheet. Heavy ring mounted in front of the boiler with removable thick stainless steel plate is fitted with heating elements and low water level cut-off device to protect these elements from burning out dry.
Front removable plate system provides easy cleaning of the deposited scale on the elements and the walls for long life and efficiency. The boiler is 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 sterilizers. It acts as a safety device, economises 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 re-energises the heating elements when pressure falls below the set point.

Heating Elements:
Flanged types, immersion heating elements are made of high grade material.

Safety Door:
Sterilizer has hinged self-locking single piece thick Stainless Steel 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 left and right of the multi port valve. A moisture trap fitted in the chamber discharge line absorbs the condensate automatically to prevent moistening of the subject matter to be sterilized.

Control Panel:
The control panel includes a pressure switch, a microprocessor based digital temperature indicator cum controller, Mains MCB, pilot lamps, relays etc. and mounted on the stand of the sterilizer for easy operation.

• 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.
• A digital temperature indicator cum controller also helps in monitoring the chamber temperature and switching off and on the heaters. 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.
• Automatic Vacuum breaker is provided to break vacuum in case of formation of vacuum due to steam condensation.
