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 tell you when the drier is exhausted.
- 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
The moisture remaining in gases dried with DRIERITE at 25° - 30° C is 0.005 mg./liter, (data verified by the National Bureau of Standards). Air is dried to a dew point of -100° F. Organic liquids are dried to the low ppm range. There is little change in efficiency at temperatures up to 100° C.
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 completely
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
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 tells 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 Du-Cal DRIERITE. DRIERITE Storage Tank Vent Driers are
efficient and economical to operate.
