Nuclear-grade, Uniform Particle Size, Gel, Strong Acid Cation Exchange Resin for Water Treatment Applications in the Nuclear Power Industry

AmberLite IRN97 H Ion Exchange Resin is designed specifically for use in nuclear loops where highest resin purity and stability are required, and where the “as supplied” resin must have a minimum of ionic and non-ionic contamination. These high standards of resin purity enable plants to achieve reliable and safe production whilst reducing the need for equipment maintenance and minimizing the impact of unscheduled outages.

AmberLite IRN97 H is a higher capacity, 10% DVB cation resin used to remove cations for purification and pH control in primary water treatment. It contains a minimum of 99% of its exchange sites in the hydrogen form. The uniform particle size and the
absence of fine resin beads result in a lower pressure drop compared to conventional resins.

The particle size of AmberLite IRN97 H is specifically designed to give an optimized balance of pressure drop, exchange kinetics, and resistance to separation from the anion exchange resin, AmberLite IRN78 OH Ion Exchange Resin, when used in a mixed bed.
