Contaminant Removal Media
Molecular sieves are synthetic crystalline aluminosilicates with uniform pores that trap water molecules.
When a gas or liquid passes through a molecular sieve bed, the water molecules are adsorbed through a highly selective process. This allows water to be adsorbed, while larger molecules, such as hydrocarbons, pass through.
Molecular sieves can achieve dew points below -100°F, making them ideal for applications requiring extremely low moisture levels, where silica gel or activated alumina do not work.
Our line of products include:
- Siliporite NK10
- Siliporite, NK30
- Siliporite NK10CL
- Siliporite OPX-R Pellets
- Siliporite G5
- Siliporite EPX-38 Beads
Silica gel is a porous, granular form of silicon dioxide (SiO2). Its highly porous structure provides a large surface area that effectively adsorbs water vapor, making it ideal for moisture control in gases and liquids.
