High-Performance Activated Alumina Desiccant (γ-Al2O3)
Engineered for Heatless & Heated Regenerative Air Dryers, Compressed Air Systems, and Air Separation Units (ASU). Achieving pressure dew points down to -70°C (-94°F) with minimal attrition.
Dew Point: Down to -70°C Static Water Adsorption: ≥ 18.0 wt% Sizes: 3-5mm (1/8"), 4-6mm (3/16"), 5-8mm (1/4")
High-purity spherical activated alumina beads with smooth surface & uniform size.
Critical Performance Features for Air Dryers
- Ultra-Low Pressure Dew Point: Exceptional pore structure allows rapid water vapor trapping, delivering consistent dew points from -40°C to -70°C.
- High Crush Strength & Zero Dusting: Superior mechanical hardness prevents bead crushing under pressure swing, protecting downstream pneumatic valves, filters, and instruments from clogging.
- Excellent Hydrothermal Stability: Resists thermal degradation during continuous purge gas regeneration cycles (170°C - 250°C).
- High Water Resistance: Maintained structural integrity even under liquid water slug impact at bed inlets.
Desiccant Grade Engineering Benchmarks
Water Adsorption Capacity
18.0 %
Static water uptake at 60% Relative Humidity (RH) ensures longer bed operation cycles.
Crush Strength (4-6mm)
180 N / bead
High mechanical resistance prevents bed compaction and channeling during high flow rates.
Attrition Rate (Dusting)
0.1 %
Minimal surface abrasion preserves downstream particulate filter lifespan.
