Scale defender


As a pioneer in the non-chemical water treatment industry for over 30 years, Fenton, Mo.-based Scale Free International LLC (SFI) has introduced the patented “Scale Defender?? and “Tower Defender?? systems. This totally eliminates the need for chemicals in boilers, cooling towers, chillers and heat exchangers. Patented microprocessor controls alter the positive nature of process water to a negative or neutral state thus eliminating scale formation and addresses microbial concerns without the use of magnets.
