Description
Premium Water Softening Resin for Residential & Commercial Systems
Aquatrol MED-CAT110E is a premium strong acid cation exchange resin designed for water softening applications. Manufactured with a 10% crosslinked gel structure, CAT110E provides excellent hardness removal together with improved physical strength and resistance to oxidation compared with standard 8% crosslinked softening resins.
CAT110E exchanges hardness-causing calcium and magnesium ions for sodium ions, making it suitable for replacing exhausted resin in a wide range of residential, commercial and industrial water softeners.
Its higher crosslink level makes CAT110E particularly suitable where longer resin life and greater durability are required, including systems operating on chlorinated municipal water.
Key Features
- Premium 10% crosslinked strong acid cation resin
- Sodium-form ion exchange resin
- Removes calcium and magnesium hardness
- Excellent physical bead strength
- Improved resistance to chlorine and oxidation compared with standard 8% resin
- Suitable for residential and commercial water softeners
- Suitable for replacement and re-bedding applications
- Regenerated using standard sodium chloride water softener salt
- Gel-type resin with uniform spherical beads
- Suitable for many Kinetico and other premium water softening systems where compatible
Why Choose 10% Crosslinked Resin?
Most standard water softening resins use an approximately 8% crosslinked polymer structure. CAT110E uses a 10% crosslinked structure, creating a stronger and more tightly bound resin bead.
This provides improved resistance to physical degradation and oxidation, which can help extend resin service life, particularly where the incoming water contains chlorine.
The additional crosslinking is primarily a durability advantage rather than simply increasing softening capacity.
Typical Applications
CAT110E is suitable for:
- Domestic water softeners
- Commercial water softeners
- Twin alternating softeners
- Automatic regenerated softening systems
- Replacement of exhausted cation resin
- Premium or high-cycle softening applications
- Selected Kinetico water softeners
- Bore and municipal water treatment applications
Always confirm the original media specification and required resin quantity for your particular softener model before replacement.

Important
Water softener resin should be installed by a suitably experienced person. Resin quantity, freeboard, distributor compatibility and regeneration settings should be confirmed for the particular water softener being serviced.
Do not completely fill a pressure vessel with resin. Correct freeboard must be maintained to allow the resin bed to regenerate and expand correctly.
