The diagram opposite illustrates
the corrosion rate, e.g. for metal,
at different humidity levels. It can
be seen that the corrosion rate is
insignificant below 50 % relative
humidity (RH) and negligible below
40 % RH.
The corrosion rate increases
significantly above 60% RH. This
threshold for damage as the
result of humidity also applies to
other materials, such as powdery
substances, packaging, wood and
electronic units.
Buildings may be dried in a variety
of ways:
The correlations occurring when
air is dehumidified are based on
physical laws.
These are depicted here in graphical
form in order to provide you with a
brief overview of the principles of
air dehumidification.
Using
Climia air dehumidifiers
• Even if windows and doors
are well insulated, water and
moisture are still capable of
penetrating thick concrete walls.
• The water required for setting
in the production of concrete,
mortar and plaster etc. may only
be diffused after 1-2 months.
• Even moisture trapped in the
masonry after high-water or a
flood is released very slowly.
• The same is also true of moisture
contained in stored materials for
example.
The moisture (water vapour)
released from parts of a building
or materials is absorbed by the
surrounding air. As a result, the
moisture content increases, which
ultimately gives rise to corrosion,
mould, rot, peeling of paint and
other unwanted damage.

1.
By heating and
air exchange:
The air in the room is heated
in order for moisture to be
removed and then this air is fed
outside. All of the energy that
is involved is lost together with
the moist air that is released.
2.
By air dehumidification:
The moist air that is present
within an enclosed space is
continuously dehumidified
according to the condensation
principle.
