Installation of these breathers has
been made quick and simple, with a direct connection to an existing breather or
vent pipe. This ensures that any incoming moisture vapour is removed before
entering the tank. The effects of air transfer will lead to a dry gas blanket
over the stored product.

A removable adsorbent container
allows the unit’s desiccant material to be changed without breaking the
breather pipe connection. Furthermore, a
distinctive change in the desiccant’s colour, signals when it is saturated and needs
to be replaced or reactivated. The colour change is from bright orange to a
distinctive dark green.

Stored products characteristics can be adversely
changed by an increase in moisture content. These effects can include: reduced
viscosity, lower electrical insulation, chemical stability and concentration.

Some of the range of
storage tank vent dryers are suitable for use in aggressive and hostile
environments such as the North Sea, and are designed for use with storage tanks
containing corrosive fluids such as acid and alkalis. Typical locations would
include chemical sites, plant works and processing installations.
