PDF datasheet mirror for LEWATIT® S 9267 (Lanxess LEWATIT). Verify with OEM before design.
Summary
Product identification
Lewatit® S 9167 is a food grade, highly regenerated mixed bed ion exchange resin. It consists of a 1:1.6 mixture of a strong acid cation exchange resin and a strong base anion exchange resin type-I. The resin mixture is ready for use without regeneration.
Applications:
- Demineralisation of potable water and process water in food applications
- Mixed bed units for polishing after primary demineralisation systems
- Demineralisation of service water in small units (e.g., laboratories, household appliances like dishwashers, steam irons, air humidifiers)
