BETE Molecular Sieve Feature:
1. Efficient desiccant
2. Consistent high adsorption speed
3. High contamination resistance
4. Strong crushing strength
5. Increasing cyclic times which provide an extended product life
3A molecular sieve
3A Molecular Sieve is primarily for removing moisture from liquefied and gaseous materials. It has an aperture size of 3A or 3 angstrom. Any molecule larger than 3A will not be able to be adsorbed. The sequence rate of adsorption rate is helium, neon, nitrogen and water.

Application:
It has become one of the most reliable desiccants for a variety of applications including:
- Refrigerant Drying
- Moisture removal in PU Plastic or Paint
- Natural Gas Drying
- Drying Cracked Gas
- Static drying of insulating glass units, whether air filled or gas-filled.
- Dehydration of highly polar compounds, such as methanol and ethanol.
- Dehydration of unsaturated hydrocarbons (e.g. ethylene, propylene, butadiene)

Packing:
Plastic bag: 30kg / bag
Stainless steel drum: 135-150kg/drum
Storage:
Keep 3A Molecular Sieve in an air tight container until ready for use to avoid unintended moisture adsorption, reseal packages after opening to prevent contamination and unintended water adsorption. We recommend that you rotate stock so oldest material is used first.
Regeneration:
3A Molecular Sieve can be regenerated and reused. To regenerate the sieve you need to remove the adsorbed moisture and other materials. To regenerate 3A Molecular Sieve need to heat up to 180-350℃ for 3-6 hours; the highest temperature should not exceed 600℃
