Specialty chemicals company LANXESS has developed the Lewatit NM 3367 mixed-bed ion exchange resin to demineralize the water used to charge and top up modern hot water heating systems. The custom-designed mixed-bed system not only prevents scale formation in the parts of a heating system that convey water but also provides lasting protection against corrosion. The specific mixing ratio takes into account the fact that anion exchange resins generally have a lower capacity than cation equivalents. The higher proportion of anion exchange resin ensures a long service life and thus highly efficient demineralization with the new mixed bed.
