VENT DRIERS 干燥器
STORAGE TANK VENT DRIERS
Use a DRIERITE Vent Drier to prevent condensation or absorption of water vapor by a material in a storage tank.
All DRIERITE Vent Driers have a sight glass window with Indicating DRIERITE to l you when the drier is exhausted.
Applications
· Guards sensitive materials against moisture
· Protects tanks, pumps and pipelines from corrosion by condensed water vapor
· Prevents biological growth by keeping out water
· Prevents contamination of valuable liquids by corrosive sludge
· Dries air to -100° F dewpoint or 2 ppm by weight
Condensation or absorption of water vapor by a material in a storage vessel can be prevented by the installation of one
of these drying columns in the vent piping. When the material in a storage vessel is removed, the moisture laden air
replacing the material is compley dried by the desiccant column in the vent line. Breathing through the vent line
occurs daily from changes in atmospheric pressure and temperature. These DRIERITE units will prevent contamination
from this source. These driers will protect storage vessels up to 400,000 gallons. The drying units will produce dry
air (100° F dewpoint) for flow rates up to 1200 gallons per minute (160 cfm). The moisture indicator eliminates
guesswork; it ls you when the DRIERITE is exhausted. The glass window has a few ounces of Indicating DRIERITE behind it.
The Indicating DRIERITE turns from blue to pink when the drier is exhausted. The drier contains the highly efficient
DuCal DRIERITE. DRIERITE Storage Tank Vent Driers are efficient and economical to operate. Refer to the Technical
Data section of this catalog for information on sizing a Vent Drier.
Window Placement
Standard driers have the sight glass window and the connection for the storage tank at the top of the drier. Low window driers
( – LW behind model number) have the sight glass and the connection for the storage tank at the bottom of the driers.
See Technical drawings and Installation drawings.
Assembly
Fill the DRIERITE Vent Drier to just above the sight glass window with 4 mesh Du-Cal DRIERITE. Then hollow out a small pocket behind the window and place a few ounces of 4 mesh Indicating DRIERITE against
the window. Quickly fill the tower with Du-Cal DRIERITE to a point 1 inch below the top outlet connection.
The upper connection of the drier is the outlet on standard driers and is connected to the storage tank through a vent line using a union or a flange.
