Compliant with industry standards and backed by 20 years of manufacturing expertise, it offers exceptional durability, reusability after high-temp reactivation, and broad industrial applications including petrochemical gas drying and refrigeration. Its robust anti-crash and anti-pollution properties ensure long-lasting performance, making it the essential moisture control solution for professionals. ## Description 3A Molecular Sieve-3A molecular sieve desiccant is a type of compound aluminosilicate desiccant whose effective pore size is 0.3nm. It is mainly used to absorb water and does not absorb and molecular larger than 0.3nm. Its application characteristics in industrial use are: rapid absorption seed, a mass of reusable times, strong anti-crash strength, and strong anti-pollution ability, which improves the use effectiveness of molecular sieve and extends its service life. It is a type of necessary absorbent material in petrochemical industry for deep drying refiling and polymerization for gas.Complies with Industry Standard, Strict Quality Control-Wisesorb 3A molecular sieve desiccant goes through strict quality control process before they are released from the factory. It complies with molecular sieve industry standard and ensure that every bottle if product are qualified and has premium quality.Wide Range of Use-Pore size of 3A molecular sieve is 3A, which is applicable for drying of all types air, hollow glass, refrigerating fluid, natural gas, methane, unsaturated hydrocarbon, pyrolysis gas, ethylene, acetylene, propylene, butadiene, etc.Rapid Moisture Absorption, Reusable-Wisesorb 3A molecular sieve has strong moisture absorption ability even under low temperature and low humidity rate. At the time, it still possesses certain moisture absorption under high temperature . It can be reactivated when dried under 550°C.How to Reactivate-The 3A molecular sieve can be placed in a muffle furnace and backed at 550°C (1020℉) for 2 hours, then transferred to a drying cylinder, and cooled to room temperature for use.20 YEARS OF DESICCANT MANUFACTURING EXPERIENCE: We have fully automated desiccant manufacturing and packaging machine manufacturing facility that is located in Marlton, NJ.
