The residential models control limescale deposits and corrosion in plumbing systems (including hot and cold water lines), water heaters, icemakers, humidifiers, and more. The Tricon International® reduces the surface tension of water, making it “wetter” or more penetrable so that soap will lather better, resulting in cleaner laundry, dishware, cars, etc. The reduced surface tension also creates a better rinsing effect that reduces or completely eliminates spotting when drying.
