Physics-Based Water Treatment for Commercial & Industrial Heat Transfer Systems

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.
