Molecular sieve 13X (so-called zeolites) are drying agents of type X and have 1-2x n-modules. As a result, the polar forces are somewhat weaker and these zeolites also selectively absorb non-polar organic substances in addition to water. These are synthetically produced aluminosilicates. Zeolites of type 13X contain sodium in their crystal lattice (Na86[(AlO2)86(SiO2)106]), the resulting pore diameter is approx. 1.0 nm. This constant structure results in a very high inner surface area of up to 1250m²/g. Together with their high electrostatic adsorption forces, these molecular sieves are therefore ideally suited for air drying.
Molecular sieves achieve a high absorption capacity even at low relative humidity. Thus they are able to dry the supply air very strongly. This makes it useful wherever the degree of drying is a decisive selection criterion. The maximum water absorption in a fully saturated environment is approx. 27%. There is no colour indicator to indicate the loading condition.
