GA 11 UPS

Strong Base Anion Exchange Resin Type - I Uniform Particle Size

DOSHION GA 11 UPS is a uniform particle size, high quality strong base type - I anion exchange resin designed for use in all general demineralisation systems. The uniformity and mean particle size of GA 11 UPS have been optimized for use in industrial equipment including mixed beds, when paired with DOSHION CSA 9 UPS.
The Characteristics of GA 11 UPS:
• Exceptional Physical stability for a conventional gel type resin which permits a long life without the development of excessive pressure drop.
• Excellent regeneration efficiency
• Ideal for demineralisation, condensate polishing and chemical process applications.
