The Protectoseal Series 782 Air Dryer provides a simple,
relatively inexpensive means of extracting unwanted moisture
from make-up air. It is recommended for tanks and systems
where the installation of an expensive central air drying or
inert gas system cannot be justified. Incoming air (from nor-
mal venting or during liquid pump-out) must pass through a
highly efficient desiccant material before entering the tank.
The desiccant is capable of absorbing a considerable amount
of moisture before it approaches its saturation point, where-
upon it can be either replaced or regenerated.
