Start with the operating problem

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.

01

Mineral Scale

Deposits insulate heat-transfer surfaces, restrict flow, increase approach temperatures, and force equipment to work harder.

02

Corrosion

Ongoing electrochemical activity can shorten equipment life, cause leaks, contaminate loops, and increase capital risk.

03

Biofilm & Biological Growth

Surface-attached growth interferes with heat transfer, contributes to under-deposit corrosion, and complicates system hygiene.

04

High Operating Cost

Excess blowdown, chemical purchasing, testing, cleaning, feed-system repairs, and energy loss can make the status quo expensive.

How Scale Free Systems works

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.

STEP 01

Evaluate the System

We review equipment, loop configuration, water conditions, operating history, existing deposits, and treatment objectives.

STEP 02

Apply the SFS System

The engineered components are selected and positioned for the specific application, then commissioned to establish continuous equipment conditioning.

STEP 03

Verify Performance

Equipment condition, inspections, operating trends, water use, maintenance activity, and site-specific performance indicators are tracked over time.

Important distinction: We do not describe SFS as simply “chemical-free.” It is a physics-based water-treatment approach that happens not to rely on continuous treatment-chemical feed for its core function.

Is SFS Appropriate for Your Facility?

Credible system selection begins with qualification. We review the complete application before recommending a conversion.

Strong candidates

Facilities seeking measurable operating improvement

  • Recurring scale, corrosion, biofilm, or maintenance problems
  • High chemical, water, sewer, cleaning, or energy costs
  • Cooling, heating, or process equipment with accessible installation points
  • A facility team willing to establish a baseline and verify results
  • Owners looking for lower long-term treatment burden
What we evaluate first

Site conditions determine the design

  • Open-loop or closed-loop configuration
  • Capacity, flow, temperature, load, and operating schedule
  • Makeup-water quality, cycles of concentration, and discharge requirements
  • Materials of construction and existing equipment condition
  • Biological-control requirements and the facility water-management plan

SFS recommendations are application-specific. Supplemental filtration, cleaning, monitoring, or other controls may be appropriate depending on the facility, source water, equipment condition, and governing requirements.

Technical questions

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.
