Applications
From insulated glass manufacturing to cryogenic air separation — SQ molecular sieves and activated alumina serve demanding industrial applications worldwide.
Insulating Glass Units (IGU)
3A molecular sieve is the industry standard desiccant inside double- and triple-pane window spacer frames. Its 3Å pore adsorbs moisture while excluding argon fill gas, preventing internal fogging for the lifetime of the window.
Oxygen Generation (PSA)
PSA oxygen systems use 5A or 13X APG to selectively adsorb nitrogen, producing 90–95% O₂ for medical, steel, and wastewater applications. 13X APG co-removes CO₂ for cleaner output and longer bed life.
Air Separation Units (ASU)
Cryogenic ASUs require ultra-dry, CO₂-free feed air before the cold box. 13X APG removes H₂O to below −70°C dewpoint and CO₂ to <1 ppm, preventing freeze-out that would block cryogenic columns.
Water Treatment & Fluoride Removal
Activated alumina removes fluoride from drinking water to WHO standards (<1.5 mg/L), and is also used for arsenic removal and air dryer beds. BET surface area ≥300 m²/g ensures high capacity and long service life.
