C-100ELT is used to produce soft-water. This media can be regenerated using sodium or potassium chloride. It is a high-purity premium grade of gel poly (styrenesulfonate) cation exchange resin designed expressly for the treatment of foodstuffs, beverages, potable waters and water used in the processing of food. C-100ELT meets the latest European standard for use in potable water applications and is in compliance with the U.S. Food and Drug Administration Code of Federal Regulations section 21, paragraph 173.25, for use in the treatment of foods for human consumption. Its high bead integrity, excellent chemical and physical stability and very low extractible content play a large part in its successful employment in these areas. In order to maintain the required standards, this product must be stored under the recommended conditions, in the packaging supplied, and be given the appropriate conditioning rinse (as laid down by the above directives) before use. Any unused resin should not be left open for use at a later date because of the possibility of external contamination. Application: This product is primarily used in water softening in a wide variety of applications from small domestic softeners to large industrial applications. Regenerated with sodium chloride or potassium chloride, the resin will give excellent softened water quality if operated within Purolite company guidelines. We do not recommend its use in demineralization.
