The Drierite Indicating Gas Drying Units can be used anywhere to provide dry air or gas for applications such as: blanketing, sample preparation, instrument protection, reaction mixtures, purging, vacuum release, venting with dry air.

Column is made of molded polycarbonate, while polycarbonate cap is fitted with o-ring gasket. Desiccant is held in place between felt filters and stainless steel supports and coil springs.

Unit will dry air to a dew point of -100° F at atmospheric pressure or pressures up to 90 psig. A simple connection by rubber hose to the bottom inlet of the dryer provides an immediate flow of dry air or gas. Continuous flows are possible with two units in the line and the necessary valves so that the exhausted column may be refilled while the alternate column remains in use.

The Indicating DRIERITE gives constant visual assurance of active desiccant. When active, Indicating DRIERITE is a distinct blue color. When exhausted, it turns pink. The zone between the two colors in the column may be a purple color and should be a sharp narrow band when the flow rate is at equilibrium. Regeneration will restore the drying capacity.

Key Features
