The hardness of the water for steam generators feeding must not be higher than 12° F (French
degrees), 6,5 dH (German degrees) or 8,4° (Clark degrees). The use of water softeners with ionic
exchange resins temporarily reduces the water hardness but it brings down the PH (acidity). PH
values lower than 6,5 indicate that water is acid, consequently corrosive. The acidity can be
neutralized from polyphosphate by means of suitable measuring caps. We advise you to have
water analyzed by qualified technicians to avoid any damage to steam generators and to water
connections
