ION Exchange Resin Cartridge and Media

Anti-scale, saltless softening, finishing and polishing using mixed-bed ion-exchange resin to
remove both positive and negatively charged ions in exchange for water forming molecules.

Consists of:
1. Cation Strong Gel Resin (Na⁺ Form) (gold)
2. Cation Weak Macroporous Resin (H⁺ Form) (white)

● Effectively combats both permanent and temporary hardness.
● Effectively reduces calcium and magnesium hardness levels in feed water.
● Prevents scaling that causes premature failure.
● Reduced energy cost in equipment longevity and less maintenance.
● Excellent selectivity of heavy metals including zinc, mercury and copper from potable
water supplies.
