DEM plants are directed to the obtaining of demineralized water through the use of specific cationic and anionic resins capable of absorbing from the water the saline and mineral part to be extracted. Thanks to this feature the installations DEM are particularly suitable for creating closed circuits of demineralized water that is constantly treated passing through the plant. A warning LED will indicate the state of saturation of resins which, once exhausted will be replaced in a simple operation which does not require
specialized technical personnel.
The plants DEM are normally used in washing machines to get a perfect absence of residues from surfaces.
