Evaporative Condensers
Protect the coil that rejects the heat.
Physics-based protection for the recirculating spray-water side of evaporative condensers used in refrigeration and industrial cooling.
Discuss your equipment →The operating challenge
Deposits affect more than appearance.
Spray water evaporates from the outside of the condenser coil, concentrating minerals in the remaining water. Deposits on coil exteriors interfere with heat rejection, while basin debris and blocked nozzles reduce coverage.
External coil scale
SFS targets adhesion on water-wetted coil exteriors. The goal is to preserve the surface through which refrigerant heat passes into the spray water and air.
Wetted-metal protection
The service plan considers coil materials, basin construction, and associated piping. Corrosion monitoring helps evaluate conditions in the spray-water circuit.
Spray-loop biological control
Where specified, copper-silver ionization supports the biological-control program. The facility continues cleaning, testing, and other required water-management measures.
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.
Protection is scoped to the spray-water circuit. It does not treat refrigerant inside the coil. Basin maintenance, nozzle inspection, conductivity control, and solids removal are coordinated with equipment-level protection.
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.
- Condensing performance at comparable load and weather
- Coil exterior condition and spray coverage
- Basin condition, conductivity, and biological trends
Questions about evaporative condensers
Is an evaporative condenser the same as a cooling tower?
No. An evaporative condenser condenses refrigerant inside a wetted coil. A cooling tower cools circulating water that usually serves separate heat-rejection equipment.
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.
