2Cooling Tower and Condenser /Chiller Systems The major problems in these water systems are:-scalesludgebio-film/slimelegionella andalgae.
3Typical scale, sludge & biofilm/slime fouling In a chemically treated Building Air-Conditioning System
4Non-Chemical Control of Scale, Sludge and Bio-film/Slime Scale-X Magnetic Fluid Conditioners can control and eliminate scale, sludge and bio-film/slime deposition in water process systems.Typical treatable scales include the following:-Calcite (calcium carbonate) Gypsum (calcium sulphate) Magnesite (magnesium carbonate) Dolomite (calcium/magnesium carbonate)
5Typical Building Air-Conditioning System Scale-X MFCs eliminate scale, sludge & biofilm/slime fouling

8Magnetic Conditioning of Water Changes Crystal Size & Nucleation IEEE Transactions on Magnetics, Vol Mag-21, No 5, Sept 1985Dr. Klaus L Kronenberg, California State Polytechnic UniversityTreated WaterThe smaller crystals have a tendency against adhesion to the surface of pipes and vessels as scaleUntreated Water

14Typical cooling tower efficiency Scale-X MFCs vs Chemical treatment
15Biofilm increases energy usage up to 4 times faster than calcium carbonate Some deposits are more insulating than others and thus have a greater impact on the head pressure and energy requirements. For example, calcium carbonate scale deposits transfer heat up to 4 times better than biofilm deposits (slime). As a result, slime increases head pressure and energy requirements and will shut down a chiller much faster than “normal” scale.HVAC Energy ConservationThrough Cooling Water TreatmentBy: A.

16Scale thickness and increase in energy usage Biofilm/slime can cause an increase in energy usage of up to 4 times that of calcium carbonate for the same thickness of buildup.
17Biofilm reduces efficiency and accelerates corrosion Biofilms also plug water passages and piping, help to accelerate corrosion, and reduce heat exchanger efficiency.Cooling Water ManagementBasic Principles and TechnologyBy: Timothy Keister, CWTFellow, American Institute of ChemistsCertified Water TechnologistProChemTech International, Inc.
18Controlling BacteriaBacteria feed on the bio-film and scale in fluid systems.By reducing and eliminating scale and bio-film, bacteria can be reduced and eliminated.Scale-X Magnetic Fluid Conditioners can control and eliminate bio-film and scale when correctly applied.
19Control of Algae, Bacteria and Legionella Scale, sludge and corrosion in the fluid systems provide the nutrients for bacteria, fungus and algae to live. Legionella lives on a bacteria in the water which derives its nutrients from the scale and sludge in the water. Magnetic fluid treatment prevents scale from forming, cleans away existing scale and the water becomes cleaner.Cooling TowersThus Scale-X MFC’s reduce and/or remove the food chain (nutrients) on which the harmful bacteria lives.This can result in a significant reduction and/or elimination of the bacteria and algae problem.
20MFC Control of Algae, Bacteria and Legionella in 29 Cooling Tower Systems A survey of 29 cooling towers using magnetic fluid conditioners and not using biocides and scale inhibitors showed no towers were a health risk and Legionella had been controlled in all towers.

23Warm Water Systems An example of treating a scaled (dirty) system. Note:- Magnetic Technology recommends that the system be cleaned before the Scale-X MFCs are installed so that bacteria and algae elimination are not delayed by the removal of existing scale.
