Many
fluids, semi-solids and powders stored in 55-gallon drums will
adsorb water vapor when exposed to normal atmospheric humidity. This
water vapor will condense, causing these substances to become
contaminated and permanently damaged from the resulting chemical
changes.
Drum Desiccant Breathers, also known as Drum Vent Dryers, prevent this contamination, which occurs during
storage and use. Changes in temperature, barometric pressure,
and fluid pumping will result in air entering the drum. This
air passes through a column of blue indicating silica gel, which
removes and retains the water vapor. The silica gel changes
from blue to pink when the desiccant is saturated and requires
replacement. The units can also be filled with orange silica gel, which is acceptable for use in the European Union. The Drum Desiccant Breather is reusable — saturated
desiccant can easily be replaced by removing the access port
plug.
The Drum Desiccant Breather begins to work from the moment it is installed. Field
testing has demonstrated that when a Drum Desiccant Breather is fitted
to a new drum of uncontaminated fluid, the air space above the
fluid is made safe from condensation within a few hours. |
