AMBERLITE™ HPR4200 Cl Ion Exchange Resin is a Uniform Particle Size, Gel, Strong Base Anion Exchange Resin for Industrial Demineralization Applications. It is a high-quality resin for use in industrial demineralization applications when high performance and cost-effective operation is required. The chemical properties and particle size of the resin have been balanced to combine excellent operating capacity with low pressure drop, while reducing chemical regenerant and rinse water usage. AMBERLITE HPR4200 Cl is compatible with all system technologies; it has the flexibility to be used in lead single or layered anion bed and in mixed bed polishers, allowing users to inventory only one strong base anion resin for their demineralization needs. In mixed bed applications, the light color of this anion resin is designed to allow easy visual distinction from the dark-colored cation resin following backwash separation. AMBERLITE HPR4200 Cl is designed for use in single bed or layered bed systems when paired with AMBERLITE™ HPR9600 or AMBERLITE™ HPR9500 Ion Exchange Resins. In mixed bed applications AMBERLITE™ HPR4200 OH Ion Exchange Resin is recommended, but AMBERLITE HPR4200 Cl may be used if chloride-form is preferred by the user.
