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 sterilizer is suitable for sterilizing hospital dressings, linen, rubber, plastic goods, surgical instruments, glassware, utensils, etc.

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 with leak-proof argon welding.
The sterilizer has a single-piece door made of stainless steel plate. The back plate and ring are 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 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 for that elegant appearance.

Steam Generator:

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

Safety Door:

The sterilizer has a self-locking, single-piece, thick stainless steel plate door that 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 an accident.

Single Point Control

A complete sterilization cycle is controlled from one point with the help of a “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 digital temperature indicator, a mains MCB, pilot lamps, relays, etc. and is 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.
  •  A digital temperature indicator and controller also help 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.
  •  An automatic vacuum breaker is provided to break vacuum in the event of vacuum formation due to steam condensation.
