Spot free DI Resin Refill
Eliminate water spots and swirl marks for good with professional-grade deionized water. Our 20" large diameter DI cartridge produces 0.1µS/cm purity water that dries completely spot-free, so you can skip the drying towel and avoid scratches entirely. The upgraded mixed-bed resin actively removes dissolved solids like nitrates, heavy metals, and salts that cause spotting and corrosion.
Perfect for detailers seeking flawless finishes, the SRDI works right from your tap when paired with a simple pre-filter, or integrates seamlessly after RO systems for ultra-pure polishing. The industrial-strength design delivers reliable performance batch after batch, protecting your vehicle's finish and eliminating the frustration of water marks.
Why Choose the Aqua Gleam SRDI?
✔ Flawless, spot-free finishes – Say goodbye to water spots on cars, windows, or equipment. DI water dries pure, leaving zero residue.
✔ Swirl-free drying – Skip the towel altogether. No contact = no scratches or swirl marks on delicate surfaces.
✔ Plug-and-play simplicity – Works seamlessly in your existing water filter system—just install and start purifying.
✔ Protects your investment – Removes corrosive ions (like chlorides) that degrade paint, metal, or lab equipment over time.
✔ Lab-grade purity on demand – Produce 0.1µS/cm water for detailing, electronics, or medical uses without expensive setups.
Features
- Mixed-bed deionization – Removes both cations and anions (e.g., zinc, fluoride, copper).
- Softening compatible – Pairs with cation resin to tackle calcium/magnesium (hard water).
- Compact but mighty – Efficient for small-batch DI production without bulky systems.
- Industrial-grade resin – Consistent performance under demand.
Specification
- Technology: Mixed-bed deionization (DI)
- Purity Output: 0.1µS/cm average conductivity
- Target Contaminants: Nitrates, zinc, fluoride, copper, dissolved ions
- Diameter: Large (20")
- Operating Temperature Range 4-45°C
- Max. Operating Pressure 5.5 bar
- Max. Operating Pressure Differential 1.0 bar
- Typical car rinse is 10-20 Litres (single filter will cover):
- 1600L @ 75mg/l TDS
- 800L @ 150mg/l TDS
- 400L @ 300mg/l TDS
How It Works
- Ion Exchange:
- Cations (e.g., calcium, copper) → Swapped for hydrogen ions (H⁺).
- Anions (e.g., nitrates, fluoride) → Swapped for hydroxide ions (OH⁻).
- Result? H⁺ + OH⁻ = Pure H₂O.
- Nitrate Selectivity: Resin prioritizes toxic nitrates, exchanging them for safer chloride ions.
- Polishing Power: When used post-RO, it scrubs residual ions for near-perfect permeate.
Pro Tip "For spot-free car rinses, pair this with a sediment filter to prevent resin fouling and maximize cartridge life."
