Deionization (DI) Systems

Semiconductor-Grade Resins

Premium ResinTech and SUEZ resins, regenerated in high-quality U.S. facilities. The same grade used in semiconductor fabs and pharmaceutical plants — not commodity ion exchange beads.

Color-Coded Quality Labels

Every tank ships with a label documenting fill date, TOC count, silica level, and rinse quality — so your QA team has documented purity data, not vendor promises.

Configurations for Every Need

Cation only, anion only, mixed bed, and activated carbon — in tank sizes from 0.25 cf to 3.60 cf plus AF Series cartridges. Right-size for your flow rate and contaminant profile.

Standard DI Tanks · 0.25–3.60 cf

Five tank sizes from compact 0.25 cf (1,750-grain capacity) up to 3.60 cf (25,200-grain capacity). Available with cation, anion, mixed bed, or activated carbon resins. Color-coded labels document fill date, TOC, silica, and rinse quality.

• 5 sizes · 0.5–15 GPM range
• Mixed Bed Column option (1.6 cf, portable)
• FRP exterior · thermoplastic interior
• Service exchange program available

AF Series Cartridges

Drop-in cartridges that fit standard residential and industrial housings (10″ / 20″ in slim or 4.5″ Big Blue diameters). Mixed bed, twin bed, layered, low-TOC, and color-changing options. Lot-traceable, FDA-approved body materials, made in the USA.

• Standard slim or 4.5″ Big Blue housings
• Ultra-pure mixed bed up to 18 MΩ-cm
• Color-changing visual exhaustion indicator
• Low-TOC and low-odor variants

Cation Exchange

SAC-H resin removes positive ions (Ca²⁺, Mg²⁺, Na⁺) and replaces with H⁺.

Anion Exchange

SBA-OH resin removes negative ions (Cl⁻, SO₄²⁻, NO₃⁻) and replaces with OH⁻.

Mixed Bed Polish

SAC + SBA resins blended in one vessel for ultrapure water up to 18 MΩ-cm.

Activated Carbon

Optional carbon stage removes chlorine, organics, and dissolved gases ahead of DI resins.
