Description

The sterilizer is based on the principle that the microbiological action of saturated steam at elevated temperatures is rapid and thorough. 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 that are commonly needed in medical, agricultural, and pharmaceutical institutions.

The high-speed sterilizer is fitted with high-wattage heaters. Primarily, it is intended for emergency sterilization of unwrapped surgical instruments and other components.

Construction:

The sterilizer is triple-walled with a steam jacket and separate boiler. The inner chamber and steam jacket are made up of heavy-gauge stainless steel sheet SS316L with leak-proof argon welding. 

The sterilizer has a single-piece door made of stainless steel plate SS316L. The back plate and ring are also made of thick stainless steel (SS316L). All the sterilizers are hydraulically tested to withstand 2.5 times the working pressure. 

The sterilizer is mounted on a tubular steel frame with ground-leveling screw flanges. The outer jacket is wrapped with glass wool to minimize heat losses due to radiation and is covered by polished stainless steel sheet SS316L for that elegant appearance.

Steam Generator:

The steam generator is made of heavy stainless steel sheet (SS316L). A heavy ring mounted in front of the boiler with a removable thick stainless steel plate (SS316L) is fitted with heating elements and a low water level cut-off device to protect these elements from burning out.

The 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 a water gauge glass for water level indication and water inlet and outlet valves.

Pressure Control:

The “PIEZOSTAT” (pressure control device) is incorporated in all sterilizers. It acts as a safety device, economizes on power consumption, 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-energizes the heating elements when pressure falls below the set point.

Heating Elements:

Flanged immersion heating elements made of high-grade material are high-wattage electric heaters that finish the sterilization within 6 minutes of achieving the desired pressure of 2.2 kg/cm2 and the corresponding saturated steam temperature of 134°C.

Safety Door:

The sterilizer has a self-locking, single-piece, thick stainless steel plate SS316L door that cannot be opened when under pressure. The self-locking device automatically removes the thread mechanism when the sterilizer is under pressure to preclude any eventuality of an accident.

Microprocessor Controller & Single Point Control:

The sterilizer is controlled by a fully automatic microprocessor controller with a color touch screen and a user-friendly interface for trouble-free operation. The microprocessor consists of test programs such as B&D tests, vacuum tests, etc. Secondly, there are eight user-selectable programs, and the user can program their own parameters into these eight freely selectable programs. Step-by-step printing can also be done by connecting a printer to the serial port. The printer is provided with the machine. The enhanced microprocessor warns in case of any alarms, malfunctions, or temperature or pressure deviations from their set parameters. The built-in audio-visual alarm system warns in the event of any malfunction. The user can also program the cycle name, batch number, operator name, and load description for documentation. In case of power failure, the user can complete the sterilization cycle using the multiport valve fitted at the 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 multiport 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 touch screen controller, Mains MCB, pilot lamps, relays etc. and mounted on the stand of the sterilizer for easy operation. 

Other Features:

  • Triple Safety: The sterilizer is provided with 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.
  • The secondary digital temperature indicator 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 release the steam in case the pressure exceeds the safety limit. All these safety features function independently of one another and sequentially, i.e., one takes over the charge in case of the other’s failure.
  • A plug screen prevents the discharge line from choking. The plug is easily removable for daily cleaning.
  • A powerful ejector for drying sterilized linen circulates air throughout the chamber. The circulating air passes through a corrosion-resistant metallic wool filter.
  • In the event of vacuum formation due to steam condensation, an automatic vacuum breaker is provided to break the vacuum.
