Intended
Use
and
System
Design
The
P2131
sterilizer
is
designed
for
sterilization
of
porous
and
nonporous
and
heat
‐
and
moisture
‐
stable
materials
(e.g.,
surgical
instruments
and
textiles)
used
in
healthcare
facilities.
The
P2131
sterilizer
is
a
rugged,
transportable
device
designed
for
field
use
in
a
variety
of
austere
environments.
Ambient
operating
conditions
include
sea
level
to
8,000
feet
altitude
and
40°F
to
130°F.
The
P2131
sterilizer
is
a
pre
‐
vacuum
and
post
‐
vacuum
sterilizer
that
has
a
conditioning
stage
with
vacuum
air
removal
before
the
start
of
the
exposure
stage,
as
well
as
a
post
‐
exposure
drying
stage
that
is
based
on
the
combined
operation
of
heat
and
vacuum.
The
sterilization
agent
is
steam
that
is
electrically
generated
in
a
jacketed
boiler.
The
P2131
sterilizer
consists
of
three
components
that
work
together
as
one
integrated
system.
These
components
are
the
(1)
Sterilizer
Main
Unit
(SMU),
(2)
Water
Recovery
System
(WRS),
and
(3)
Sterilizer
Water
Softener
(SWS).
The
WRS
reclaims
hot
condensate
and
exhaust
steam
for
re
‐
use
by
the
SMU.
The
WRS
also
includes
a
water
eductor,
which
provides
the
vacuum
capability
for
the
pre
and
post
‐
vac
phases
of
sterilization.
The
SWS
deionizes
the
incoming
water
to
prevent
scale
buildup
and
reduce
the
effects
of
water
on
the
metal
components.
A
manual
hand
pump
is
also
provided
with
the
SWS
to
pull
water
from
a
Jerry
can
or
bucket
if
a
pressurized
water
system
is
not
available.
The
P2131
sterilizer
is
an
automated,
microprocessor
‐
controlled,
pre
‐
vacuum
autoclave.
A
visual
alert
indicator
(LED
light)
and
an
audible
alarm
notify
the
operator
of
any
abnormal
condition
during
operation.
It
has
a
fully
jacketed,
horizontal
‐
type
pressure
vessel
and
is
designed
as
a
transportable
sterilization
unit.
The
P2131
sterilizer
is
of
welded
‐
aluminum
alloy
construction
to
minimize
weight.
The
chamber
assembly,
with
internal
dimensions
of
16
″
diameter
x
36
″
long,
is
supported
in
a
combination
frame
and
endcap
assembly
to
provide
rigidity
and
protection.
The
endcaps,
when
closed,
completely
enclose
and
protect
the
sterilizer
and
provide
the
capability
to
serve
as
a
shipping
container.
When
the
endcaps
are
opened
they
provide
an
integral
stand,
placing
the
sterilizing
chamber
and
operating
controls
at
a
convenient
working
height.
Universal
shelves
are
supplied
to
provide
three
shelf
levels,
the
top
two
in
any
combination
to
provide
flexibility.
The
shelves
are
removable
and
stack
for
compact
storage.
The
sterilizer
is
designed
to
use
the
jacket
as
a
steam
boiler.
Electric
immersion
heaters
boil
the
water
and
produce
steam.
Water
is
retained
in
the
jacket
of
the
sterilizer,
and
when
it
is
heated,
the
steam
is
directed
through
a
solenoid
valve
and
tubing
into
the
chamber.
A
baffle
disperses
the
steam
as
it
enters
the
chamber.
A
water
level
sight
glass
is
located
at
the
rear
of
the
SMU.
A
low
‐
water
cutoff
switch
is
provided
for
protection
of
the
electric
heating
elements.
In
addition,
