Challenges
Take control of your climate
From food to archives to utilities, data centers or
defence, nearly all industries have climate control
challenges. Moisture, temperature and air quality
are all factors that can impact processes throughout the world. And without proper humidity control,
excess environmental moisture can lead to unexpected downtime, defective products, safety andhealth issues, and fincancial losses.

But you can address the unique climate challenges
you face with a tailored Munters dehumidification
solution. Proven, energy-efficient air treatment from
Munters will help you optimize your indoor climate
for long-term, sustainable business.

Bacterical growth, mould
and fungus
Moist air which is laden with bacteria can increase the potential
for contamination in production
and storage. When the humidity
level is higher than 70% RH, mold,fungus, and mildew flourish.
From raw materials, production,
packaging through transport andstorage. All products and buildings are affected by high relative
humidity. The product’s lifetimeand quality can be significantly
improved with dehumidification.

Chemical reactions

Condensation

Moisture or water vapour is one of
the components which can cause
an undesired chemical reaction.
For instance, lithium (used in the
production of lithium batteries)
will react violently with water
vapour. This is why production oflithium batteries can only be donein an extremely dry (dehumidified)area. Also explosives and propellants are known to be sensitive tochemical reactions with moisture.

When water evaporates it
becomes water vapour. When thiscomes into contact with cool surfaces, condensation forms. This
could drip onto walls, ceilings,
and products, which will increase
the risk for product contamination, as well as for a decrease insafety and product quality.

Controlling humidity using dehumidificaiton will prevent undesired reactions that might leadto an unstable product, dangerof explosion, or the forming of
unwanted and dangerous chemical compounds, for instancehydrogen gas.

Dehumidification systems create
low humidity atmospheres toprevent this contamination andto reduce the medium for mould
and microbe formation. Using a

Ice build up

Moisture absorption

Mechanical properties

Product caking/sticking

Close control

Corrosion, or the oxidation of
metal, is heavily influenced by thepresence of moisture in the air. A
high relative humidity causes athin layer of water vapor molecules to settle on the surface ofthe metal.

Ice and frost build up effects productivity, quality and safety.

The climate needs to be strictly
controlled during production,
packing and storing of hygroscopic products. Moisture absorption can disturb the precise
function of a final product, justas the shelf life is affected if the
product takes up moisture during
production. Some products
need to be produced and packed
in environments with relative
humidity levels below 25% RH.

Materials are in balance with
their surroundings. In wet climates materials will take up
more moisture from the air, in dry
climates the opposite occurs. In
some cases this can influence themechanical properties of materials. Paper that is too wet will not
be straight anymore. Some typesof moisture-sensitive glue willloose their bonding power, andnylon will absorb so much moisture that product size and tolerance is impacted.

Many powders and products
attract and retain moisture. Whenthese products are stored in silos
or bins, or transported in pneumatic conveying systems, moisture can cause these ingredientsto stick to silo walls and cause
blockages. Lower productivity, higher production costs andreduced product quality are theresults of these problems.

Munters provide complete packaged climate control solutions,providing precise humidity andtemperature control with varying
levels of filtration.

Dehumidification can lower relative humidity to 45–50% without
any problem, stopping corrosion.
This will dramatically reduce
damage and maintenance costs.
Proven applications
Steel storage
Military equipment andVehiclesLeisureSuspension bridges
Water treatment works

A dehumidification solution will
help to maintain the highest
safety levels by stopping ice andcondensation in their tracks. No
ice means workers won’t slip andequipment won’t be damaged byfalling ice. No mist means reduced
accidents due to reduced visibility.
The improved climate conditions
also enhance the efficiency of
evaporators and freezer equipment by preventing ice occurring,ensuring better performance,
reducing defrost cycles andsaving on maintenance costs.
Eliminating fog and mist insidecold stores will improve visibility
and safety.

Product coating

Product drying

Spray drying

Waste heat

When hygroscopic ingredientsand powders absorb moisturethey become sticky and build up
inside the conveying lines. The
resulting flow problems slow theprocess, create hygiene concerns and eventually cause costly
downtime.

Coating processes can be shortened and made more consistentby adding dry air. Regardless ofthe season, climate conditions
in coaters will be stable all year
round thereby securing optimal
conditions. Productivity increases
and energy costs may be cut. The
risk of contamination of the conditioning system by any wet return
air would be eliminated by using a
Munters desiccant dehumidification system.

The most common method for
product drying is to introduce hot
air, thus evaporating the moisture
contained within the product.
However this is not ideal as theincrease in heat and humidity
increases the risk of mould andfungus growth. This in turn cancause corrosion to machinery andthe extra heat can damage theproduct being dried.

Spray drying is common practice
all over the world for a variety of
products. In hot and humid conditions, the spray drying process
is susceptible to seasonal fluctuations. Changes in the ambient
weather influence the conditions of the inlet air to the drying
process and the consequences
are low drying capacity, heavy
process fluctuations and difficulties in drying the more sensitive
products.

Utilise heat generated fromsources such as CHP. This cancome in the form of low pressure
hot water (LPHW), typically 85°C.

Pre-drying the air using a Muntersdehumidifier ensures that the
products are transported in a dry
environment. The result is quick
and continuous problem-freeconveying with no unscheduled
production stops.

Data centres

Defence

The right indoor climate is essential for data centers. Efficiently
maintaining the right conditions
can improve reliability, reduce
operating costs and ensure thatthe data center is run in a moresustainable way. The equipment
within a data center generates asignificant amount of heat, andoperates most efficiently and reliably within certain temperature
ranges. Incorrect moisture levels
within data centers can lead toelectrostatic discharge or corrosion, which can damage servers,
while inadequate ventilation cancompromise working conditions.
Munters solutions can efficiently
maintain the perfect indoor climate with proper ventilation andhumidity control.

The climate in and around military and aerospace equipment,
systems and components has adirect influence on the quality andcondition of the items. Controlled
humidity environments save on
maintenance costs, as well as
ensuring equipment availability
is increased. In addition, dry air
reduces and even stops corrosion by lowering relative humidity
levels to around 40–45%. On
infrastructure as well as on itemswith organic material, mould
and fungus growth will also be
stopped. And ammunition chemical compound degradation isslowed down or can even be
stopped, optimising their safe
shelf life.
Proven applications
