AmberLite HPR550 Cl

Summary

Product identification

AMBERLITE™ HPR550 Cl Ion Exchange Resin is a uniform particle size, gel, strong base anion exchange resin. It is designed for condensate polishing and mixed bed demineralization applications in the power industry.

This resin was previously sold as DOWEX MONOSPHERE™ 550A Ion Exchange Resin.

Applications

• Mixed bed condensate polishing in fossil power plants
• Mixed bed polishing in industrial demineralization
• Demineralization, particularly for:
  • Water with a high percentage of silica
  • Achieving the lowest silica leakage
  • Removal of strong and weak acids
• Single bed industrial demineralization requiring high water purity
