RELITE CNS - Weakly Acidic Resin

RELITE CNS is a weakly acidic resin used for water softening. It has a high operating capacity, excellent physical stability, and small volume changes. It is especially suited for very hard waters due to its first-class kinetics and resistance to stress. RELITE CNS can also operate at temperatures up to 100°C. It has a porous acrylate-DVB matrix and complies with food processing regulations.

RELITE CNS - Weakly Acidic Resin

TDS 10031

RELITE CNS

RELITE CNS is a new porous weak acid cation exchanger having an acrylic matrix.

This resin is characterised by very high operating capacity, excellent physical stability, and relatively small
volume change on conversion to the monovalent alkali form. The first class kinetics and resistance to attrition
and osmotic shock make RELITE CNS especially suited for application in the most exacting of conditions eg
very high temporary hardness waters either in the hydrogen or monovalent alkali form. A further aspect of
stability (see Recommended Operating Conditions, below) is the ability of RELITE CNS to perform at
temperatures up to 100°C.

The composition of this resin complies with the existing food processing rules and regulations.
