    2. 3A-XH Molecular Sieve Desiccant for Refrigerants3A-XH molecular sieve desiccant for refrigerants is silica aluminates in potassium and sodium form with a pore opening of 3 angstroms or 0.3 nm. It is a generic kind of desiccant, which can be classified as three types of molsieve adsorbent, XH-7 type, XH-9 type and XH-11 type.
    2. Activated AluminaActivated alumina features numerous microporous channels and large specific surface area for the use of adsorbent, desiccant, catalyst and so on. With strong affinity to water, oxide, acetic acid, alkali and more, our product is not only micro water depth of desiccant, but also an adsorbent which adsorbs polar molecules.
