AmberLite HPR550 H

Summary

Product identification

• Product Name: AmberLite™ HPR550 Cl Ion Exchange Resin
• Product Type: Uniform Particle Size, Gel, Strong Base Anion Exchange Resin
• Intended Applications: Condensate Polishing and Mixed Bed Demineralization Applications for the Power Industry
• Previous Name: Previously sold as DOWEX MONOSPHERE™ 550A Ion Exchange Resin.

Description

AmberLite™ HPR550 Cl Ion Exchange Resin is a high-capacity resin designed for high purity industrial demineralization and condensate polishing in power stations. It features exceptional bead integrity and rapid exchange kinetics due to its small average particle size, making it suitable for high flowrate demands. Its uniform bead size and light color are intended to complement AmberLite™ HPR650 H Ion Exchange Resin for easy visual confirmation of separation. It can be used as an alternative to the OH-form for mixed bed polishing with strict silica specifications.

Applications

• Mixed bed condensate polishing in fossil power plants
• Mixed bed polishing in industrial demineralization
• Demineralization, especially when treating water with a high percentage of silica, or when the goal is removal of strong and weak acids with minimal silica leakage.
• Single bed industrial demineralization requiring high water purity.

Resin Pairings

• Recommended: AmberLite™ HPR650 H Ion Exchange Resin (gel)
• Additional Options:
  • AmberLite™ HPR1600 H Ion Exchange Resin (gel)
  • AmberLite™ HPR2000 H Ion Exchange Resin (macroporous) – for external regeneration systems.
