The Scale Free System is a patented, non-chemical water treatment technology that prevents scale formation, corrosion, and microbiological growth. It works by neutralizing the electrical activity in pipes and equipment using a control panel and grounding system, without altering water chemistry. Scale Free Systems has been in business for 15 years providing this service nationally and internationally. The document discusses the technology and its benefits over chemical water treatment, including reduced operating costs, increased efficiency, and sustainability advantages. It provides examples of applications and customer installations in various markets.

1. NON-CHEMICAL WATER TREATMENT

2. What is the Scale Free System?
• Industry leading, patented technology
• “Green" alternative to water treatment that prevents and
reverses scale formation, halts corrosion and prevents
microbiological growth for all heat transfer systems without
the use of chemicals
• Best non-chemical water treatment system available on the
market today utilizing “system neutralization” technology.
• Reduces water usage, energy consumption and operating
costs while eliminating chemicals from your facility
• Unlike all other non-chemical systems, SFS does NOT
attempt to change or alter water chemistry in any way,
rather SFS treats and protects your equipment
History of Scale Free Systems, Inc.
• Established 15 years ago in St. Louis, Missouri
• National and International provider of water treatment

3. Threats to Your Bottom Line
Scale Bacteria Corrosion
Scale, Bacteria & Corrosion will Destroy Your Equipment…leading to costly
capital budget expenditures for equipment replacement.
Scale is the biggest problem associated with
the efficient and cost-effective operation of
your heat exchange equipment.
Studies have shown that as little as an ⅛” of
scale formation on heat transfer surfaces
can lead up to a 15% increase in energy
consumption.

4. Protect Your Bottom Line
SFS neutralizes the pipes and equipment shell to the same
polarity as the ions in the water.
Engineered application pulls the dynamic electrical energy
out of the water, through a control panel that regulates
and controls the energy flow and ultimately out to an
independent grounding system.

Growth
SFS utilizes Copper-Silver Ionization for microbial control;
a dispersive process that introduces stable, long-lived,
positively charged copper and silver ions into the water
system to destroy biofilms and slimes that can harbor
harmful bacteria.
Safe ionic concentration levels are maintained by regular
monitoring of the water in the system, offering additional
long-term residual protection.
Halt
Corrosion
SFS eliminates the electrical bridge that starts the harmful
corrosion process.
By neutralizing electrical activity, chemical decomposition
necessary to produce free oxygen and free hydrogen in
solution (agents responsible for pitting and corrosion) is
eliminated.

7. Microbiological Control
COPPER-SILVER IONIZATION is approved by the US EPA (as per its Safe Water
Drinking Act) for biological treatment of domestic water supplies against
infections of Legionella, E. Coli, Salmonella and a host of other microbes as
well. It is a dispersive process that introduces long-lived, stable, positively
charged copper and silver ions into the water system.
1- The copper-silver ionization process is provoked by
running DC voltage between the copper and silver
electrodes submerged in water, thereby releasing the
positively charged Cu and Ag ions into the water.
2- Having water flow between the electrodes carries
away the metallic ions into the water system.
3- Once in the water reservoir, the positively charged
copper and silver ions bind themselves to and attack
negatively charged microorganisms such as
Legionella bacteria and commence the biocide
process.
4- Upon contact with these microorganisms, the
copper-silver ions attack in a multiphase process to
disrupt the overall cell metabolism causing cellular
lysis (death). Safe ionic concentration levels are
maintained by monitoring the water system and thus
offer additional long-term residual protection.

9. Reuse Blowdown Water and Save!
SFS Biological Control is compliant with EPA standards for drinking
water quality set forth in the Safe Drinking Water Act (SDWA).
All blowdown water exiting the system is compliant with the Federal
Water Pollution Control Act.

10. Sustainability: SFS Green Solution
• Immediately reduce the environmental footprint of a facility by eliminating
toxic water treatment chemicals.
• Installing SFS presents a compelling opportunity to generate operational
savings while treating water in an environmentally friendly manner.
PLUS - Use of SFS will also earn points in the LEED system.
• Chemical-free discharge water can be reused for other purposes on site
instead of being sent to a treatment facility.
• The cycles of concentration will increase inside the system, saving water
and reducing costs.
• SFS provides a distinct environmental advantage, while mitigating the risk
of accidental chemical spills, chronic exposure and bioaccumulation of
persistent chemicals in the food chain.

11. Essential Cooling Tower Treatment
Good Tower Treatment
STARTS with:
• Knowledge of makeup water
chemistry and operating
conditions.
• A treatment system designed
to meet scale, biological and
corrosion control.
• Good conductivity control.
• Consistent monitoring and
maintenance of the system.
Good Tower Treatment
ENDS with:
• Water and energy savings.
• Lower facility operating and
maintenance costs.
• Clean condenser tubes and
good heat transfer.
• No corrosion of equipment
surfaces and piping.
• Reduced environmental
footprint by eliminating
chemicals – Reuse
Blowdown!

12. Why Should You Consider
Non-Chemical Water Treatment?
• Cooling system operation represents 12-18% of an
industrial building’s operating costs.
• Poor water treatment reduces operating efficiency by
as much as 25%.
• SFS reduces water consumption by increasing the
cycles of concentration through the system over what a
chemical treatment program can achieve.
• More cycles means less water consumed!
• Environmental standards groups such as LEED are
encouraging facility owners to implement changes that
positively impact the environment while protecting the
bottom-line.
• Facility owners and managers are increasingly aware of
the safety and liability risks/costs associated with the
storage and handling of chemicals on-site.
