A.
Multifunctional
boiler compound
|
These
products are
one-liquid-multifunctional
boiler compounds.
They have the
effects of easing
scale and corrosion
inhibition,
sludge dispersion,
dissolved oxygen
removal and
pH adjustment.Feed
water hardness:
< 100 mg/LBoiler
pressure: <
10-20 kgf/cm2Suitable
for cylindrical
boilers and
water-tube-boilers |
W-100
series
|
B.
Boiler compound
(for high
hardness)
|
This
product can
be used to boilers
where raw water
is used as feed
water without
additional pretreatments.
Regardless of
pressure conditions,
it prevents
scaling and
turns hardness
components into
soft flowing
sludge that
can be discharged
during blowing. |
W-116
|
C.
Boiler compound
(for water
tube)
|
These
products are
used in small
size tube boilers
where contact
temperature
is extraordinary
high and general
boiler compounds
are unsuitable
to be used.
Especially it
is good for
boilers with
steam amount
lower than 1ton/day. |

(for food
grade)

|
D.
Non-PO4
type boiler
compound
|
These
products are
non-PO4 multi-functional
boiler compounds
that can substitute
boiler-compounds-for-high-hardness-systems
(dosage is too
high). They
are composed
of specific
polymers therefore
they are good
choices in case
phosphate regulations
apply. |
W-117~W-120
|
E.
Boiler compound
(for high
pressure)
|
This
product is used
in boilers where
pure water is
used as feed
water or pressure
is over 40kgf/cm2 |
W-113
|
| F.
Oxygen Scavenger |
These
products are
input into boiler
supply water.
By removing
oxygen in the
tube water,
it can prevent
oxygen-induced
corrosion problems. |

| G.
Corrosion inhibitor
(for condensate) |
These
products are
volatile amine
anti-corrosion
agents. They
can adjust the
pH of feed water
and condensate
water to weak
alkaline conditions
and inhibit
corrosion. They
are used together
with oxygen
scavengers when
applying boiler
compounds for
high hardness
systems. |
W-134,135 |
| H.
Corrosion inhibitor
(for hot water) |
This
product is a
scale inhibitor
only used in
hot-water room-heating
boilers where
temperature
is between 70-160°C
and pure water
or soft water
is used as feed
water. |
W-181 |
| I.
Corrosion inhibitor
(for shutdown
boiler) |
These
products are
used to inhibit
corrosion when
boilers are
necessary to
be shut down
temporarily
or for a long
time for maintenance
purposes. |
W-161
W-162 |
| J.
Ion exchange
resin cleaner |
These
products are
used to recover
the properties
of ion exchange
resins when
they are contaminated
with Fe or organic
compounds and
show lowered
performances. |
W-171,
172
W-173 |
| K.
Cleaning agent |
These
products are
used to clean
the cutting
oils, grease
dirt, sands,
and mud scales
present in the
tube lines of
new boilers
or the interior
parts of appliances,
also they can
be used to clean
pipelines contaminated
with scales
or by corrosion
during operation. |
W-5100
series |
| L.
Neutralizer
and anti-corrosion
agent |
This
product is used
to neutralize
and prevent
corrosion after
acid cleaning. |
