Application

<p style="text-align: justify;">
<strong>Activated Alumina Desiccants:</strong></p>
<p style="text-align: justify;">
Activated Alumina Desiccants is a porous form of aluminum oxide. It has a high surface area which adsorbs vapors without any change in form. Activated Alumina Desiccants  will not soften or disintegrate easily when immersed in water.</p>
<p style="text-align: justify;">
Dew points to -40°F and lower may be achieved with Activated Alumina Desiccants  depending on dryer design and operating conditions.</p>
<p style="text-align: justify;">
The 1/8” (2-5mm) bead is the size most frequently used in regenerative dryers.</p>
<p style="text-align: justify;">
The 3/16” (4-8mm) bead is used when pressure drop and surface area requirements fall between 1/8” and 1/4” material.  It is suitable for most systems.</p>
<p style="text-align: justify;">
The 1/4” (5-10mm) bead Activated Alumina Desiccants  is used both as a pre-bed material to support large desiccant beds or as a buffer for silica gel beads. Pressure drop is slightly lower than 1/8” (25mm) material. </p>
<p style="text-align: justify;">
If size is not known or specified, the 1/8” (2-5mm) size is usually satisfactory. However, if Activated Alumina Desiccants is used in a regenerative dryer and the desiccant retaining screens cannot be measured, the 1/4” (5-10mm) size should be used as a bed support (6” layer). If at all possible, obtain a sample and measure it  before ordering.</p>

Using Procedure

<p style="text-align: justify;">
<strong>Product Benefits:</strong></p>
<ol>
<li style="text-align: justify;">
<strong>High adsorption capacity</strong>. With high surface area and excellent pore distribution, Activated Alumina Desiccants  has a high water adsorption capacity. This reduces initial cost, energy consumption and operating costs through smaller bed sizes and/or longer operating cycles.</li>
<li style="text-align: justify;">
<strong>Low abrasion. </strong>Insures less dusting during tower depressurization or loading. Low abrasion means low pressure drop and a reduced chance of plugging the afterfilter.</li>
<li style="text-align: justify;">
<strong>Resists liquid water.</strong> Water slugging due to upstream failure of aftercooler, separators or drain traps will not fracture the alumina beads. The adsorption capacity of the desiccant can be restored after complete regeneration.</li>
<li style="text-align: justify;">
<strong>High crush strength.</strong> High crush strength, which limits dusting, is important during loading of desiccant towers. High crush strength makes alumina effective as a prebed material when used with other types of desiccants.</li>
<li style="text-align: justify;">
<strong>Uniform bead sizes.</strong> Activated Alumina Desiccants is a uniformly sized bead. It provides low pressure drop to minimize channeling and ensures utilization of the full bed column section.</li>
