How FRE-FLO™ Technology Works

Upon entering a FRE FLO™, water experiences a pressure drop and turbulent flow. This causes dissolved carbon dioxide (C02) to become a gas in the water (much like bubbles in carbonated water).

The pressure drop changes the chemical characteristics of the water, producing a "saturated" condition with respect to calcium carbonate. This means the water in the FRE FLO™ is ready to precipitate or grow crystals of calcium carbonate (calcite). Calcium carbonate is commonly called "scale."

As the saturated water travels over the core in the FRE FLO™ housing, the core promotes the nucleation or growth of scale crystals. However, the force of the water passing through the FRE FLO™ continually keeps the core free of scale. The crystals are then carried out of the unit suspended in water.

The benefit comes as the FRE FLO™ treated water passes through applications such as cooling towers, ice and coffee machines, humidifiers, misting systems, evaporative coolers, or any system that uses water. At locations where scale would ordinarily grow on equipment surfaces, the scale now grows on the scale crystals grown within the FRE FLO™ (because the crystals that were generated within the FRE FLO™ function as alternative growth surfaces). This process can also attract and eliminate scale that was present in the equipment before the FRE FLO™ was installed.

In essence, FRE FLO™ takes existing total dissolved solids (TDS) and, through the processes of epitaxial nucleation and lattice matching, converts a portion of the TDS to suspended solids. That portion of the TDS that is converted to suspended solids protects the equipment from the growth of scale. The crystals stay suspended within the system and are discharged when the water exits the system.

The equipment stays clean and the scale goes down the drain. FRE FLO™ works with nature to prevent scale from growing on your equipment.
