The Griswold SBC represents the most advanced non-chemical water treatment device on the market today.  Griswold had done pioneering research into the use of high frequency  electromagnetic energy to alter the way calcium and other minerals precipitate.  Instead of precipitating as hard insulating scale that clogs pipes and inhibits heat transfer, minerals precipitate as a free-floating powder which flows harmlessly through the system until it is flushed out during blowdown.  The SBC uses four independently controlled coils and a unique SBC AutoSeek™ feature to assure most efficient tuning in any water condition.
