Like other physical water treatment devices, EMS applies electric force on ions in water, especially Ca++ and HCO3–, moves them in opposite directions, and turns some of them into neutral crystals suspended in water. These crystals, which we call “seeds”, absorb free ions and prevent them from adhering to surfaces and forming harmful limescale deposits.
The main idea behind EMS which makes it unique in the family is how it produces and applies electric force: EMS acts like a transformer. It uses a chain of electromagnetic bars as a core of the transformer, the primary winding is within the EMS while the pipe and water in it play the role of the secondary winding. This causes the electric force to apply throughout the pipe which means everywhere in the water loop the “seeds” are being produced. Another benefit of this would be the ease of EMS installation: it needs no cutting nor welding or any other intervention.
