Unleash the power of our revolutionary and unique patented water treatment process. The Scale Defender System & The Tower Defender System are non-chemical, non-magnetic processes that eliminate and reverse scale and corrosion in cooling towers, boilers, chillers, heat exchangers, evaporative condensers, and storage tanks. Biocide and conductivity requirements are also integrated through SFI -patented solid-state controllers. Imagine never having to worry about EPA requirements, chemical shipping & freight costs or storage & handling costs. It’s environmentally safe and pollution free! Forget about cleaning and disposal of chemical drums. Acid cleaning or rodding of tubes becomes a thing of the past. All this makes the SFI process system marketable to commercial, institutional, industrial, food/beverage and shipping industries. Other benefits include a reduction of: Water Treatment Costs Labor Costs Sewer Costs Water Costs Energy Costs Maintenance Costs

SFI's unique process also dramatically increases service life of pumps, piping, cooling towers, evaporative condensers, boilers, heat exchangers, and other related equipment. Elimination of algae and slime growth is another huge benefit to SFI’s patented biocide control process. Again, it’s chemical-free & non-magnetic which means no more biocides, algaecides, corrosive oxidizers or chlorine-bromide. This time-proven method has been used by NASA since the 1960’s. Silver/copper ions are released into the water at less than 50% of what the EPA will allow in drinking water, and it's pollution free and environmentally safe. Scale Free International provides an engineered application of various metals placed in such a manner so that the greatest amount of dynamic electrical energy will be collected and grounded out from the heater, condenser, boiler or other equipment in question, thus removing the cause of scale formation, pitting and corrosion, as well as the cause for lowered heating efficiency. Probes & Control Monitor Boiler Scale Scale Free International’s patented water treatment process has been installed in 80 plus locations throughout the Midwest region. High-rise apartment complexes, hospitals, dairy processing plants, sewage treatments plants, and bottling companies are some examples of our clientele benefiting from scale removal and elimination.
