SILVERBLUE is the latest generation softening system that uses the entire volume of resin, regenerating only the one actually used with an immediate saving of water and salt. The microprocessor considers water consumption and, based on this, calculates how much salt and water are needed for the subsequent regeneration. The operating mode used is that of the ‘‘blocked bed’‘ with counter-current regeneration. E-VOGLIO! It can regenerate in TIME, DELAYED VOLUME, IMMEDIATE VOLUME, and FORCED 7-DAY modes. Drinking water treatment equipment per Ministerial Decree 25/12 and Ministerial Decree 174/04.
