DuPont™ AmberLite™ IRA402 Cl Ion Exchange Resin – Industrial Demineralization Essential for Reliable Water Purification

As a classic strong base anion exchange resin under DuPont’s AmberLite™ series, the IRA402 Cl model stands out for its balanced performance, long service life, and wide adaptability. Designed specifically for industrial demineralization scenarios, it efficiently removes silica, strong/weak acids, and harmful anions from water, making it a trusted choice for chemical plants, power stations, electronic factories, and other industries requiring high-purity water. Below is a detailed breakdown of its core advantages, technical specs, and purchasing options to help you make an informed decision.
Why Choose DuPont™ AmberLite™ IRA402 Cl?
1. All-Round Demineralization Performance
• Targeted Anion Removal: As a Type I strong base anion resin, it excels at capturing negatively charged ions like chloride (Cl⁻), sulfate (SO₄²⁻), and silica (SiO₂) – critical for solving scaling and corrosion issues caused by high-silica water in industrial equipment.
• High Exchange Capacity: With a total capacity of >1.2 eq/L (Cl⁻ form), it adsorbs more anions per unit volume, reducing resin replacement frequency and lowering operational costs.
• Low Silica Leakage: Optimized for high-silica water treatment, it minimizes silica residue in treated water, protecting boilers, heat exchangers, and precision instruments from scaling damage.
2. Stable & Durable for Long-Term Use
• Strong Mechanical Strength: ≥90% whole uncracked amber spherical beads resist breakage during backwashing and regeneration, extending service life in continuous industrial operations.
• Controlled Swelling: Swelling rate ≤20% when converting from Cl⁻ to OH⁻ form, avoiding equipment clogging or resin bed deformation caused by excessive volume changes.
• Wide pH Adaptability: Stable across pH 0–14, it handles acidic/alkaline water sources without additional pH adjustment, simplifying system design.
3. Versatile for Industrial Systems
• Ideal for Co-Flow Regeneration: Tailored for co-flow regenerated systems (a common design in industrial water treatment), it ensures uniform regeneration and consistent performance.
• Broad Compatibility: Works seamlessly with DuPont cation resins (e.g., AmberLite™ HPR1200 H) to form complete demineralization systems, meeting diverse water purity demands.

FAQ
Q1: What’s the difference between Type I and Type II strong base anion resins?
A1: Type I resins (like IRA402 Cl) have higher thermal stability and silica selectivity, making them ideal for high-temperature, high-silica water; Type II resins have faster exchange rates but lower stability, suitable for general demineralization.
Q2: How often does the resin need regeneration?
A2: Regeneration frequency depends on water anion concentration and system flow rate. For typical industrial demineralization (anion content 100–500 ppm), regeneration is required every 1–2 weeks. Our team can provide a precise schedule based on your water analysis.
Q3: Can it be used in drinking water treatment?
A3: Yes – when paired with food-grade regenerants, it meets WQA NSF/ANSI standards and can be used in drinking water pre-treatment to remove harmful anions like nitrate.
