WHAT
DOES THE M.F.C. DO?
(a) It prohibits scale and wax
build-up in pipes and equipment.
(b) It
progressively removes solids from existing pipes,
boilers, water towers, heat exchange units, production
equipment, portable domestic hot water systems etc.
(c) Removal or elimination of
solid deposits from the walls of the pipe or surfaces of
equipment greatly reduces the incidence of
"under deposit" pitting corrosion cells
from forming. Also a system
clean of scale deposits is much easier to keep free of
bacteria, fungus and algae.
3. HOW DOES IT DO
THIS?
The fluid
to be treated is accelerated through controlled and
intensified magnetic fields
creating enormous molecular excitation that affects
the size of particles of
precipitated compounds, the ability of crystals to
form, changes their shape and
alters the solubility of compounds.
In the case of calcium carbonate the
larger, misshapen crystals or flocculated particles will not
coagulate to form scale in the same way that smaller normal
crystals would.
Secondly the equilibrium between the
fluid and the existing scale is
disrupted by the larger crystals. Smaller particles, in
general, dissolve more easily so larger particles reduce the
local concentration of calcite
in solution-and remove the
existing scale.
4. HOW
LONG IS THE CLEANUP PERIOD?
The clean up period will take from
several weeks to several months because of many variables.
The type of scale or
combination of materials, the
temperature it has been exposed to as well as the velocity,
turbulence and conductivity of the
fluid are some of the variables.
5. WHERE DOES THE
SCALE GO?
Some of the dissolved solids are
precipitated to form large random shaped crystals which when
wet will settle out as sludge or when dry become amorphous
powder. This sludge will settle to the bottom
of boilers or in the basin of cooling towers where they are
removed by blow down or flushing.
Side stream solids separation
equipment can be effective in
removing these solids from some
systems. A portion of the existing scale will
return to solution and be
carried away in the bleed off.
The rest of the scale may fall
off in softened
pieces and have to be physically removed
from the system several times
during the clean up period. It is a slow but safe way to
remove scale.
6. WILL
IT WORK ON ALL TYPES OF
WATER?
The MagTek fluid conditioner is most
effective in hard water, salt
water and soft treated water. It also works very well
combined with chemical treatment so changing
from chemical to magnetic
treatment is easy. The combination of both chemical and
magnetic treatment makes the clean up
faster.
The reaction in highly conductive
seawater and oil field
production water is more pronounced. Scale problems in oil
well pumps have been eliminated with M.F.C.’s where the total
dissolved solids have been over 200,000 P.P.M. and the
hardness more than 20,000 P.P.M.
7. WILL IT TREAT
LARGE SYSTEMS?
There is no limit to the size that
M.F.C.’s can be built. They can be manifolded and only the
required number of units used to meet the
flow rate. One large unit can
treat the discharge of many pumps. Smaller units on the
discharge of each pump may be required if
the pumps cycle on/off. Units
have been installed on recirculation systems in excess of
30,000 feet in length.
8. IS THE M.F.C.
A WATER SOFTENER?
No. The
M.F.C. is not a water softener;
it does change the state of the
solids in the water and reduce
surface tension. In most cases
the use of a water softener can
be discontinued. An exception may be a boiler under
heavy load with no condensation
return and a very hard raw water supply.
If scale control has not been
achieved with a water softener
and chemicals, then leave the existing treatment in place
until control is achieved with the magnetic unit.
. Scale control chemicals can
then be cut back or eliminated. Just getting the scaling
problems under control will make the M.F.C. cost effective in
severe cases as the above-described boiler.
9. DO
I STILL NEED CHEMICALS?
The Magnetic treatment replaces the
chemicals in most cases except for an
Algaecide to control bacteria,
fungi and algae. You will experience a reduction in the
amount of algaecide used in
conjunction with the M.F.C. compared to chemicals only.
Steam
Boiler applications where mechanical de-gassing is not used
will require continued chemical treatment for dissolved
oxygen and carbon dioxide. These chemicals are only a small
portion of the overall chemical cost if chemicals only are
used.
10. WILL THE SYSTEM
SCALE UP AGAIN?
If the magnetic units are installed
and then the system neglected it will start to clean then
scale up again. The magnetic system is much easier to
maintain than a chemical only system. However, during the
clean up period solids must be flushed
from the system and correct
bleed off or blowdown
procedures followed.
After the initial clean up
period, the system will be very easy to maintain.
11. HOW DO I KNOW
IT'S WORKING?
(a) BOILER?
Visual inspection before and 30 to 60 days
after the M.F.C. installation
will demonstrate the clean up. Although
a T.D.S. continuity test will
indicate its reaction-the
operator or plant supervisor has schedules set up for
blowdown according to P.P.M. concentration in boiler water.
Our unit will increase the reading, showing the scale coming
into suspension and requiring more frequent
blowdowns initially. As the
scale is removed, the T.D.S. -
P.P.M. will again recede and blowdown should be
sequenced to maintain the
correct T.D.S. Because of the removal of existing deposits,
the heat exchange will be better and
fuel consumption will go down.
(b)
AIR CONDITIONING EQUIPMENT?
Monitor the
temperature spread across the condenser and watch it return
to the original specs. Since the condenser increases in
efficiency, the load can be reduced. Record this change to
calculate savings. Head temperature and oil temperature both
will decrease. This load change has two primary benefits,
(a) dollars saved in energy consumed, and (b) increases life
of equipment.
(c)
INDUSTRIAL HEAT EXCHANGERS?
Monitor in/out temperatures and pressures on both sides of
the heat exchanges as it returns to the original specifications.
(d)
DOMESTIC HOT WATER SYSTEMS?
Potable water can be safely treated with magnetics. MagTek
M.F.C.'s do not introduce any
foreign contaminates which would
alter the purity. Normal blowdown of the storage tank
will reveal a residue of crystal deposits being discharged
form the bottom drain.
Scheduled blowdown of the hot water storage tank should not
be neglected. By monitoring, you will note an increase in
temperature of the return hot water line. You will also note
a shorter recovery time. This indicates a more efficient heat
exchanger. Sectioning a piece of the water line at a remote
location will provide a method to
visibly inspect the removal rate. Water flow rates will
increase at all points in the system.
12.
WHAT ABOUT PRESSURE
DROP?
As the fluid to be treated is
accelerated through the magnetic fields
a pressure drop occurs across the M.F.C. This pressure drop
can be as little as one PSI or
as much as 10 PSI depending on
the system. As a general rule 2-6
PSI is normal.
The feet of head, pump specs. type of
system, flow rates required, etc., are all
taken into consideration in selecting
the right size and model M.F.C. for
your system. The pressure drop and more are gained back when
the frictional losses due to
scale are eliminated from the
system.
13. HOW ARE M.F.C.'S
INSTALLED?
Any person with a basic understanding
of elementary pipe fitting can install the magnetic
units in the pipe. At your request MagTek, Inc. will provide
you with a detailed instruction manual or insure that one of
our Reps. are present for the installation.
Our sales reps. will be pleased to inspect your system and
gather information to properly
size your M.F.C.'s.
