The operating challenge

Deposits affect more than appearance.

Thin plates and closely spaced passages make deposit control especially valuable. Scale adds thermal resistance; accumulated solids and biological fouling can restrict water flow.

01 / PROTECTION FOCUS

Surface protection

SFS targets the water-contact surfaces where mineral deposits adhere. The objective is to maintain useful heat transfer through plates or tube walls.

02 / PROTECTION FOCUS

Metal protection

Metallurgy, dissimilar-metal connections, and water conditions inform the corrosion-control plan. Inspection and corrosion trends are used to evaluate performance.

03 / PROTECTION FOCUS

Flow-path cleanliness

Biological control is included where the water circuit calls for it. Strainers, filtration, and scheduled cleaning address debris and solids that electrical treatment does not physically remove.

How SFS fits

We treat the equipment.

SFS focuses on the electrical environment at water-contact equipment surfaces. Its scale-control approach is designed to discourage mineral adhesion, while its corrosion-control approach addresses electrical conditions at those surfaces.

Scale and corrosion protection use the specified controller, probe, and grounding configuration. Biological control is a separate treatment function where included in the project scope.

Your application

A protection plan built around your system.

Each fluid circuit is evaluated independently. A treatment connection on one side does not establish protection of the other side. Access, gasket compatibility, pressure ratings, and existing maintenance procedures are considered during scope development.

Minerals do not disappear. Released deposits and suspended solids still need an appropriate removal route. Performance depends on equipment condition, water quality, operating conditions, and the agreed service program.

Measure the result

Start with a baseline. Track the change.

Use operating records and inspection results to assess protection over time. Compare like-for-like conditions so weather, load, and flow changes are not mistaken for treatment results.

  • Approach temperature at comparable flows and loads
  • Pressure drop across the treated water circuit
  • Plate or tube condition during planned inspection

Questions about heat exchangers

Does this work on both exchanger designs?

Plate-and-frame and shell-and-tube equipment can be evaluated. Suitability depends on the specific water circuit, materials, duty, and access; the installation is not one-size-fits-all.

What does SFS need to evaluate my equipment?

Share the equipment model, water circuit layout, operating temperatures, current treatment program, recent water tests, and any scale or corrosion photos. SFS can then review the application and discuss an appropriate scope.
