Steri H.P. Rectangular Horizontal Sterilizer
Bearing ISI Mark : is 3829 I
The sterilizer is based on the principle that microbiological action
of saturated steam at elevated temp is rapid and thorough. All models
work on downward displacement of air principle which is most economical
method of obtaining for all types of bulk sterilization which are
commonly needed in Medical, Agricultural and Pharmaceutical institutes.
Suitable for sterilizing hospital dressings, linen, rubber plastic
goods, surgical instruments, glasswares and utensils etc.
Robust and rugged all weld construction which is leak proof unlike
riveted construction. Inner chamber is made of thick plate of Mild
Steel of non magnetic stainless steel of 304/316 quality and jacket
is made out of rolled steel.
Sterilizers will have single door made out of rolled steel lined
with S.S. sheet on both sides. All the sterilizers are hydraulically
tested to withstand 2.5 times the working pressure.
The steam jacket is lined on the outer side with asbestos sheet
or glass wool which prevent heat losses due to
radiation and is covered by strong rolled steel sheet duly painted.
Made of thick stainless steel plate suitably located under the sterilizer.
High grade flanged type heating elements are fitted from front side
for easy replacement/repair. Fitted with water gauge glass for water
level, safety valve, water inlet and drain valves. It is also provided
with Low Water Level cut off device. This device protects the heater
in the generator from burning out dry. The steam pressure in the
boiler is indicated on a individual pressure gauge.
Safety Lock for Door
Every horizontal rectangular sterilizer is fitted with SELF LOCKING
SAFETY DOOR which cannot be opened when the chamber is under pressure.
The clutch mechanism automatically disengages the threads of the
radial locking system for precluding any eventuality of accident
when the chamber is under pressure. A heat resistant Neoprene Rubber
gasket ensure steam tight fitting.
Electrically operated PIEZOSTAT (Pressure Control Device)
is incorporated in all electrically operated sterilizers. It economises
power consumption and limits the use of release valve which would
frequently blow steam into the room.
It cuts off the power supply to heaters when the set pressure is
achieved and re-energises heaters when pressure falls down.
Complete sterilizing cycle is controlled from one point with the
help of Multi port valve fitted at front top. Two speeds
of exhaust are available for evacuating.
Two separate valves provided for evacuating air and steam from inner
chamber and jacket as and when desired. A steam trap is fitted in
the chamber discharge line to eliminate the condensate automatically.
Houses the Pressure control switch, Main switch, Pilot lamps, relays
etc. and mounted on the stand of the sterilizer for easy operation.
TRIPLE SAFETY : The sterilizer is provided with triple safety.
(a) By a pressure control switch which automatically limits the
pressure to the required set valve.
(b) Two spring loaded safety valves one each at chamber and boiler
(c) A dead weight safety valve at chamber level.
A PLUG SCREEN prevents the discharge line from choking. The
plug is easily removable for routing cleaning.
A powerful Ejector (for drying sterilized linen) circulates
air through the chamber. The circulating air passes through a corrosion
resistant metal wool filter.
A Dial thermometer is provided to show the chamber temperature.
AUTOMATIC VACUUM BREAKER is provided to break vacuum case
of vacuum formation due to steam condensation.
