The sturdy, convenient, time-saving unit will dry approximately 2200 liters of air, saturated with moisture at 21°C and 740mm pressure, to a dew point of approximately minus 79°C

When exhausted, the Drierite® may be regenerated by heating in very thin layers (one granule deep) in an open pan or tray, and with careful handling, the drying unit will last indefinitely. The tower is made of acrylic plastic with anodized aluminum cap. Packed with 8 mesh indicating Drierite.

Gases when expanded from a compressed state are not saturated with water, and the drying unit will, therefore, dry several times the volume of gas noted for saturated conditions. For maximum efficiency, the gas flow should not exceed 200 liters per hour. Intermittent requirements for dry gases are readily available by simply making a rubber tube connection between the laboratory bench air line or gas cylinder and bottom inlet of the drying tower.
