Activated
Alumina
Van Gas activated alumina is a porous form of aluminum
oxide in the shape of a bead. The large surface area
of the activated alumina bead maximizes the adsorption
of moisture vapor. Van Gas Activated Alumina desiccant is used for drying small quantities of instrument gas and for use in heatless regenerative dryers. |

Silica
Gel
Available in indicating and non-indicating form, Van
Gas silica gel beads are of uniform size that contain
an immense network of inter-connecting microscopic pores.
These pores allow for excellent moisture retention through
physical adsorption and capillary condensation. Van Gas Silica Gel desiccant is used for drying small quantities of instrument gas and for use in heatless regenerative dryers.

Molecular
Sieve
Van Gas molecular sieve adsorbent desiccant is capable
of adsorbing water molecules over a much wider range
of temperatures than any other desiccant material. Molecular
sieve also has a much higher equilibrium capacity for
water vapor under very low humidity conditions. Van Gas Silica Gel desiccant is used for drying small quantities of instrument gas and for use in heatless regenerative dryers.
