Device for chemically treating of Water, in particular to avoid boiler scale

摘要

The unit, consisting of a cylindrical housing (2) containing a chemical treatment cartridge (9) for water entering through an inlet (4) and circulating through an annular cavity (16) between the housing and cartridge before passing through the latter to be treated by the chemicals (10) inside it, includes a second cartridge (13) that surrounds the first to filter sediments. The filter cartridge surrounds the chemical treatment one to form a second annular cavity (15). The first cavity receives the incoming water, while the second delivers filtered water to the chemical treatment cartridge. The two cartridges are installed with seals (14) between the two cavities, and the filtered water enters the chemical treatment cartridge through radial holes (12) at its end furthest from the inlet, passing out through a sieve (17) at the top that retains the limescale and corrosion-inhibiting chemicals.
