Protect Heat-Transfer Equipment With Physics—Not Chemistry
Scale Free Systems provides a physics-based approach to controlling mineral scale, slowing corrosion, and inhibiting biological growth in cooling towers, chillers, boilers, heat exchangers, and evaporative condensers.
We treat the equipment—not the water.
The Information Your Team Needs to Evaluate a Change
Whether you design the system, install it, maintain it, or approve the investment, SFS supports a disciplined technical and financial review.
Mechanical Engineers
Application review, system requirements, equipment compatibility, technical documentation, and coordination for the basis of design.
Mechanical Contractors
Clear installation scope, piping and electrical coordination, startup support, and practical scheduling around facility operations.
Facility Teams
Lower treatment burden, fewer scale-related cleanings, simpler operation, measurable inspection points, and ongoing support.
Owners & Finance
A site-specific view of capital cost, water and sewer savings, energy impact, avoided maintenance, and expected payback.
What Is Your Current Program Failing to Control?
Treatment should be judged by equipment condition and operating results—not only by the presence of chemicals or a monthly service report.
Mineral Scale
Deposits insulate heat-transfer surfaces, restrict flow, increase approach temperatures, and force equipment to work harder.
Corrosion
Ongoing electrochemical activity can shorten equipment life, cause leaks, contaminate loops, and increase capital risk.
Biofilm & Biological Growth
Surface-attached growth interferes with heat transfer, contributes to under-deposit corrosion, and complicates system hygiene.
High Operating Cost
Excess blowdown, chemical purchasing, testing, cleaning, feed-system repairs, and energy loss can make the status quo expensive.
Control the Conditions at the Equipment Surface
Conventional programs primarily manage bulk-water chemistry. SFS takes a different approach by continuously conditioning the equipment environment where scale adhesion, corrosion activity, and biofilm formation occur.
Evaluate the System
We review equipment, loop configuration, water conditions, operating history, existing deposits, and treatment objectives.
Apply the SFS System
The engineered components are selected and positioned for the specific application, then commissioned to establish continuous equipment conditioning.
Verify Performance
Equipment condition, inspections, operating trends, water use, maintenance activity, and site-specific performance indicators are tracked over time.
Designed Around Heat-Transfer Equipment
SFS is evaluated and sized for the actual application—not offered as a one-size-fits-all device.
What Changes When You Move Beyond Chemical Dependency?
The goal is not change for its own sake. It is cleaner equipment, more stable performance, lower operating burden, and results that your team can verify.
| Evaluation Area | Traditional Chemical-Dependent Program | Scale Free Systems Approach |
|---|---|---|
| Primary focus | Maintain target chemistry in the circulating water. | Condition the equipment environment where deposits, corrosion, and biofilm affect performance. |
| Ongoing inputs | Chemical delivery, storage, feed pumps, calibration, dosing, and frequent adjustment. | Installed system components, electrical operation, inspections, and application-appropriate monitoring. |
| Scale management | Keep minerals suspended or chemically inhibited under maintained control limits. | Reduce the tendency of minerals to adhere to equipment surfaces and support gradual release of existing deposits. |
| Maintenance burden | Inventory, handling, feed-system service, testing, and corrective dosing. | Simplified routine operation with focus on system verification and equipment condition. |
| Performance evidence | Water-analysis reports plus equipment inspections. | Equipment inspections, operating trends, water use, maintenance records, and agreed site-specific measurements. |

Frequently Asked Questions
Does Scale Free Systems treat the water?
SFS is designed to condition the equipment environment rather than maintain performance through continuous adjustment of bulk-water chemistry. That is why we say SFS treats the equipment—not the water.
Is SFS just a magnet, coil, or signal device?
No. SFS is an engineered system selected for the application and designed around measurable equipment conditions, system components, installation requirements, and ongoing verification. A technical review is used to explain the proposed configuration for each site.
Can SFS remove existing scale?
SFS is intended to prevent mineral adhesion and can support the gradual release of existing deposits over time. The rate and extent depend on deposit composition, thickness, equipment condition, operating conditions, and water characteristics. Heavily fouled equipment may require an initial cleaning plan.
What happens to corrosion?
SFS is designed to slow and control the electrochemical conditions associated with corrosion. Existing damage cannot be reversed, so baseline inspection, metallurgy, operating conditions, and follow-up measurements remain important.
How does SFS address biological growth?
SFS is designed to inhibit biological growth and biofilm formation as part of the overall equipment-conditioning approach. Site-specific monitoring and the facility’s water-management obligations still apply. SFS should not be presented as a substitute for required Legionella risk management, testing, or regulatory compliance.
Will installation require a shutdown?
Shutdown requirements depend on the application, piping, electrical scope, and available isolation points. SFS develops the installation plan with the owner, engineer, and contractor so work can be coordinated around facility operations.
How will we know the system is working?
The verification plan can include baseline and follow-up equipment inspections, approach temperatures, water and sewer consumption, energy trends, maintenance activity, cleaning frequency, corrosion indicators, and microbiological monitoring appropriate to the site.
Can SFS work in hospitals and other critical facilities?
SFS has experience in demanding commercial and institutional environments. Every critical-facility application requires a site review, coordinated installation plan, documented responsibilities, and continued compliance with the facility’s water-management program and applicable requirements.

For Industry Professionals
Questions Engineers & Facility Teams Ask
Evaluating water treatment for your facility or your next project? Start with these questions about Scale Free Systems, equipment requirements, and measurable performance.
How does Scale Free Systems work?
SFS uses physics-based equipment conditioning designed to control electrical conditions at equipment surfaces. The goal is to reduce scale adhesion, address corrosion, and inhibit biological buildup in heat-transfer equipment. Our focus is the equipment and its surface conditions. SFS does not use magnets or coils.
What types of equipment can be evaluated for SFS?
Applications include cooling towers, chillers, boilers, heat exchangers, and evaporative condensers. Suitability depends on the specific water circuit, equipment materials, operating temperatures, water quality, and system layout. Boiler and closed-loop applications need their own technical review; a cooling-tower application should not be assumed to apply to every system.
Can SFS be installed on existing equipment?
Contact SFS to evaluate a retrofit or a new project. For an existing system, provide equipment information, piping drawings or photos, current treatment details, and recent water reports. The project review should establish connection locations, access, electrical requirements, and any necessary modifications before installation is scheduled.
Will installation require a shutdown?
Shutdown needs depend on the approved installation design and site conditions. Confirm any piping work, isolation, electrical work, and commissioning requirements with SFS and your mechanical contractor. Include the agreed outage window and startup responsibilities in the installation scope.
Can SFS help with existing scale buildup?
SFS is designed to prevent new scale adhesion and help reduce existing mineral deposits over time. Results and timing depend on deposit composition, severity, and operating conditions. Heavily fouled equipment may still need cleaning, and loosened material needs an appropriate removal path. Establish a baseline inspection and follow-up schedule to evaluate progress.
Can we stop using our existing treatment chemicals?
Any change to chemical treatment should follow a documented, site-specific transition plan. Review water chemistry, equipment requirements, corrosion monitoring, and biological controls with the responsible treatment and facility professionals. Do not discontinue existing treatment solely because new equipment has been installed.
Does SFS replace a Legionella water management program?
No. Equipment conditioning does not replace a facility's Legionella water management program. Cooling towers still need appropriate monitoring, cleaning, disinfection, and corrective actions. Claims about general biological control should not be treated as proof of Legionella control.
See the CDC cooling tower guidance for water management considerations.
How should we verify scale and corrosion performance?
Agree on baseline measurements and acceptance criteria before making a change. Depending on the system, evaluation may include repeatable surface inspections, deposit records, corrosion coupons or probes, water analysis, and operating trends. Compare equivalent operating conditions and use qualified interpretation of the results. Photos are useful supporting evidence, but should accompany measurements.
What energy, water, and cost savings should we expect?
There is no single savings percentage or payback period that applies to every facility. Build the business case from your current energy use, makeup and blowdown water, sewer charges, treatment costs, cleaning, and maintenance. Compare those costs with the full proposed installation and service costs. Adjust performance comparisons for changes in load, weather, and operating hours.
Will we still need blowdown, filtration, and routine maintenance?
Plan to retain the operating controls and maintenance your system requires. Equipment conditioning does not make dissolved solids or debris disappear. Review blowdown settings, solids removal, strainers, filtration, inspections, and cleaning as part of the treatment design. Any change to these practices should be supported by operating data.
What technical information should engineers request?
Request the proposed equipment specifications, installation drawings, electrical requirements, materials compatibility, operating limits, and commissioning procedure. Also confirm available monitoring outputs, any building automation integration, and the supporting performance evidence for a comparable application. Verify model-specific capabilities before adding them to project specifications.
What should be included in the service agreement?
Define who handles startup, inspections, sampling, reporting, cleaning, and corrective action. Confirm service frequency, response arrangements, consumables, warranty terms, and any performance commitments in writing. Review equipment manufacturer requirements before changing the treatment program.
What do you need to evaluate our facility?
Start with your equipment type and capacity, location, operating schedule, recent water reports, and the problem you want to solve. Photos, piping diagrams, maintenance history, current treatment costs, and utility records help clarify the application and establish a useful performance baseline.
