The challenge
Atmospheric air contains moisture which is a problem to materials and manufacturing
processes.
—Cold stores
—Utility buildings
—Computer rooms
—Switching and power stations
—Electronics production
—Pharmaceutical production
—Manufacturing areas
—Process drying
Protect your environment
A false economy
Even when you cannot see it, moisture
in the form of water vapour is all around
us, held in suspension in the air. The
relative humidity of the air in many cases
determines the extent of corrosion of
certain materials, the speed at which
moulds develop and the rate of increase
of bacteria that cause decay. Most
materials and goods are best stored under
cool dry conditions.
Traditionally the problem was disguised by
the use of heat or ventilation. This process
is exceptionally energy inefficient and
reliant on introducing outside air that is
generally not suitable unless expensively
heated. Drying by traditional heating
involves continuously warming a stream of
outside air on a constant ‘in and out’ cycle.
—Bottling and food plants
—Archives, museums and
libraries
—Sports halls
—Wet clothes drying rooms
—Ice rinks
—Boiler rooms
—Ship building and offshore
—Underground rooms
—Drying flooded areas or new
buildings
—Preservation of buildings,
plant, ships, drilling platforms
and turbines
Heating and ventilation
is extremely energy
inefficient and
expensive. Luckily
a solution does
exist to make the
air drier without
heating – Calorex
dehumidification
—Applying industrial coatings
—Maintaining bridges and locks
Relative humidity
Relative humidity (RH) is the expression
used to define how much water
vapour can be held in the air at a given
temperature as a percentage of what it
could contain at saturation (100% RH).
That is when the relative humidity reaches
the level at which air can hold no more
moisture. The maximum amount can vary
according to its temperature – warmer air
is capable of holding more moisture than
colder air.
The challenges of excess
moisture:
—Corrosion
—Product deterioration
—Condensation
—Damp
—Mould and mildew
—Prolonged drying
—Manufacturing delays
—Discomfort

Relative humidity in %
With an RH of over 60% the rate of
corrosion on steel rises rapidly. At an
RH of approximately 50%, virtually no
corrosion occurs.

The solution
The Calorex answer to this problem is its wide range
of dehumidifiers suitable for every environment from
warehouses and sub-stations to museums and garages.
A better way
Problem solved
Dehumidification is much more
sophisticated than heating. It recirculates
the same air and physically removes
moisture from it. This alleviates the need
to continuously reheat incoming air. Not
only that, a dehumidifier will cleverly
convert energy taken out of the room
as moisture (latent energy), to create
‘sensible energy’ that can be used to heat
the room, accelerating the drying process.
Our wide range of units and operating
temperatures ensure there is a system to
fit every need. From high tech problems
requiring sophisticated ‘total loss’ or ‘keep
dry recirculation’ systems to a simple
off the shelf mobile dehumidifier to plug
in and go - Calorex are unique problem
solvers in their field.

The process of dehumidification involves moisture-laden air being drawn into a
dehumidifier where the air passes across a refrigerated coil. The air is rapidly cooled
below its dew point, condensing the water vapour and recovering its latent heat
energy for re-use. The cooled air is then passed across the condenser where it is
reheated and returned to the served area at the required lower relative humidity.
