Molecular sieves beads and pellets are applicable in different industries, some of which include medicals, refineries, natural gas, coal chemical, and oxygen generation among others. Our expertise in the supply of quality molecular sieves has allowed us to work with clients from all over the world. Molecular sieve 4A, also called zeolite 4A, is one type of aluminosilicate crystal with average pores measuring 4 angstroms (0.4 nm). Molecular with kinetic diameter smaller than 4 angstroms will be adsorbed by zeolite 4A, otherwise, be excluded.4A molecular sieves are typically used for dehydration in the air brake systems, natural gas drying.
We are excited for our work and how it positively impacts clients.

Why we focus on Natural Gas Molecular sieves are crystalline compounds created from alumina silicates, with controlled and precise structures, which contain pores of uniform size. These compounds have an affinity for various molecules, especially for polar compounds such as water, hydrogen sulfide and carbon dioxide. Molecular sieves can therefore be used for removing water from sour gas, or t...
The need of dry air in various industry production As a process, air drying takes away the moisture from the air, keeping the machinery and equipment running uninterrupted. This is an energy-efficient and cost-effective method of maintaining moisture levels within the area, which can help reduce production and maintenance costs.
The product should be stored in original pack or air-proof package in cool and dry conditions should not be left exposed to open air.
Molecular sieve 4A can be regenerated by increasing temperature or reducing the pressure.
