Use a <strong>Vent</strong> Drier to prevent condensation or absorption of water vapor by a material<br />
in a storage tank. All <strong>Vent</strong> <strong>Driers</strong> have a sight glass window with Indicating<br />
desiccant to tell you when the drier is exhausted.<br />
Applications<br />
<strong>Storage</strong> <strong>Tank</strong> <strong>Vent</strong> <strong>Driers</strong><br />
• Guards sensitive materials against moisture<br />
• Protects tanks, pumps and pipelines from corrosion by condensed water vapor<br />
• Prevents biological growth by keeping out water<br />
• Prevents contamination of valuable liquids by corrosive sludge<br />
• Dries air to -100° F dew point or 2 ppm by weight<br />

NEE # Construction<br />
Condensation or absorption of water vapor by a material in a storage vessel can be prevented by the<br />
installation of one of these drying columns in the vent piping. When the material in a storage vessel is<br />
removed, the moisture laden air replacing the material is completely dried by the desiccant column in<br />
the vent line. Breathing through the vent line occurs daily from changes in atmospheric pressure and<br />
temperature. These dryer units will prevent contamination from this source. These driers will protect<br />
storage vessels up to 400,000 gal-<br />
lons. The drying units will produce dry<br />
air (-100° F dew point) for flow rates<br />
up to 1200 gallons per minute (160<br />
cfm). The moisture indicator elimi-<br />
nates guesswork; it tells you when<br />
the desiccant is exhausted. The glass<br />
window has a few ounces of indicat-<br />
ing desiccant behind it. The Indicating desiccant turns from blue to<br />
pink when the drier is exhausted. The drier contains the highly ef-<br />
ficient Du-Cal desiccant. <strong>Storage</strong> <strong>Tank</strong> <strong>Vent</strong> <strong>Driers</strong> are efficient and<br />
economical to operate.<br />

There is also a Model 1600 which is the maximum size for a housing based on Du-Cal density. The design flow rate is 120 CFM with maximum pump out rate (no<br />
more than 2 minutes) of 240 CFM or 1800 GPM. It removes 60 pounds of water and has a 4” NPT connection and maximum working pressure of 1 psi.<br />
