1.      WHAT IS A (M.F.C.) MAGNETIC FLUID CONDITIONER?

(a) The M.F.C. unit is a series of very powerful magnetic circuits mounted in a case equipped with standard pipe threads or flanges at each end.

(b) Diameter and length of the M.F.C. will depend on the volume of fluid to be treated and the intensity of treatment. Length will vary from 12 to 48 in.

(c) Installation is in line with the piping so that all the fluid passes through the M.F.C.

(d) "State of the Art" RARE EARTH permanent magnets make the M.F.C. self powered with a life expectancy of decades.

(e) No external electrical power or recharging is needed.

(f) Normally, the diameter of the M.F.C. will be the same or close to the diameter of the system piping and seldom more than one or two pipe sizes larger or smaller. M.F.C.'S are sized by flow rate not line size.

Always consult your Mag-Tek distributor or factory for correct flow rate/unit size.

 

2. 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 MagWell 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 recirculating 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 Algacide to control bacteria, fungi and algae. You will experience a reduction in the amount of algacide 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. MagWell 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 MagWell, 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.
