Steri H.P. Cylindrical, Horizontal Sterilizer
Bearing ISI Mark : IS 3829 I
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
Suitable for Sterilizing hospital dressings, linen, rubber, plastic
goods, surgical instruments, glasswares, utensils etc.
Triple walled with steam jacket and separate boiler Inner chamber
and steam jacket are made up of Heavy gauge S.S. Sheet with leak
proof argon-arc welding.
The sterilizer has single piece door made of stainless steel. Back
plate and ring is also made of thick stainless steel sheet. All
the sterilizers are hydraulically tested to withstand 2.5 times
the working pressure.
Mounted on tubular steel frame with ground levelling screwed flanges.
The Outer jacket is wrapped with asbestos sheet or glass wool to
minimise the heat losses due to radiation and is covered by polished
stainless steel sheet for that elegant appearance.
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 efficiency.
Fitted with water gauge glass for water level indication, water
inlet and outlet valves.
The PIEZOSTAT (Pressure control device) is incorporated
in all electrically operated sterilizers. It 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.
Flanged type, immersion heating elements are made of high grade
material and duly ISI marked.
Sterilizer has hinged self-locking single piece thick S.S. 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.
Houses the PIEZOSTAT, main switch, 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. 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 takes over the charge in case of others
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.
