Product Overview
3A 8x12 Molecular Sieve Desiccant by Delta Adsorbents is a high-performance zeolite desiccant engineered for selective moisture removal in industrial and commercial processes. With a nominal pore size of ~3 Å, it efficiently adsorbs water molecules while excluding larger compounds such as unsaturated hydrocarbons and highly polar alcohols (e.g., methanol, ethanol). This makes 3A molecular sieves ideal for applications where water control is critical but product purity must be preserved.
Where it fits
- Gas drying: removal of water vapor from natural gas and process gases
- Ethanol dehydration: efficient drying of ethanol for fuel-grade and industrial applications
- Air drying: moisture control in compressed air and pneumatic systems
- Insulated glass units: prevents fogging and condensation in double-pane glass
- Cryogenic operations: moisture removal in ultra-low temperature environments
Key advantages
- High adsorption capacity for water vapor at standard conditions
- Precise 3 Å pore size excludes larger hydrocarbons and alcohols
- Strong crystalline structure with excellent mechanical durability
- Performs reliably in cryogenic and low-temperature processes
- Available in multiple industrial packaging options: 220 lb drums, 2000 lb super sacks
