Why
dehumidification?
- Corrosion
Iron and steel will not rust if the air in contact with the
surface has a humidity below 50% relative humidity (RH)
- Condensation
Moisture will not condensate on a surface if the air in contact
with it has a dew-point lower than the surface temperature
- Ice
formation
Ice will not form on a surface if the air in contact with it
has a dew-point lower than the surface temperature
- Handling
of hygroscope materials
The quality of dry drugs, dry food, hard candy and other hygroscope
materials can only be maintained through production to the consumer
if it is kept in contact with air at a low relative humidity
- Drying
buildings
When drying moisture from a building, whether it is a new building
or a building with water damages, the most effective way is
to use sorption dehumidifying
- Mould
Mould and fungus formation is prevented if the surrounding air
is kept below 70%RH. This is important in many situations, for
example in storage of wooden products
- Product
drying and cooling
When drying and cooling products a low relative humidity is
essential for a fast process. If the products to be dried are
sensitive to high temperature, the low relative humidity can
only be obtained with dehumidification
- Bacteria
Bacteria need humidity to survive and multiply. Often the humidity
required for bacteria to multiply is found on hygroscope materials
- Odours
Unpleasant odours, will drastically be reduced if the relative
humidity is kept below 50%RH. For example in sewage stations
the odours can be controlled by installing a dehumidifier.
Applications:
- Pharmaceuticals
Dry air is most important during the production as well as during
the storage of pharmaceutical products.
- Food and confectionery
- Dry air storage
Dry air storage is used for a variety of materials, such as
corn, coffee, powders, sugars and electronic equipment. As the
name indicates, dry air is essential for maintained quality.
Using air is far more economical than heating and ventilating
large storage areas.
- Dehumidification of
indoor ice-rinks
- Dehumidification of
storage tents
- Power stations
Machinery
installed in power plants require protection against moisture.
Evaporation occurs from water surface and pipes containing
water resulting in high humidity conditions within the normally
well insulated buildings. Condensation will occur whenever the
warm air comes into contact with the surfaces of pumps and pipes
containing cold water.
- Waste water purification
plants/pump stations
- Defence
Military storage:
Since the 1970's, desiccant equipment has been used by the military
all over the world for preservation by dehumidification. Inactive
ships, tanks, aircraft, weapons and supplies are kept in dry air
storage, provided by dehumidifiers. The technology enables an
increased combat readiness and decreases the preservation costs
drastically.
Example of dehumidifiers
from Seibu Giken DST AB:
CF-152 of the Flexisorb
series Industrial sized dehumidifier. This unit was sold by ExactAir
- Saudi Arabia
Products:
All DST dehumidifiers contain
the SSCR-rotor from Seibu Giken, a guarantee for high quality.
Small
dehumidifiers
DR/DC-series
Stainless steel units. These dehumidifiers are used for purposes
such as dehumidification in military warehouses, hydropower plants
and for permanent installations in areas with relatively low moisture
levels.
DR-40/50
DR -40 and DR-50 are easy to maintain. The components are easy
to disassemble.
DR-40 and DR-50 are suitable for several applications, for example
cold and dry air storages and cargo protection. The DR-40 can
be delivered with a 10A or 16A fuse.
Medium-sized
dehumidifiers
The R-060BR and R-061R are stainless steel units used in fields
such as process industry, warehouses, plastic halls or in the event
of serious water damage. The
R-series
For larger applications. Double skin insulation and built-in
fans. It has been widely used in for example pharmaceutical applications
and confectionery production.
The
RZ-range
The RZ-range consists of three compact units made of
galvanized steel with fans on the outside. Ideal for the process
industry, for example.
Flexisorb
-dehumidifiers for industrial applications
Flexisorb mean flexibility. The Flexisorb range has been developed
by DST to satisfy the varying requirements of the industry. Flexisorb
units are modular in their design, and have tremendous potential
to be adapted according to the specific requirements of each application.
Contact your nearest agent for more information.
Flexisorb uses the Recusorb, Consorb, Econosorb or Flexisorb dehumidification
principle.
Aquasorb
A-30B
Aquasorb is a sorption dehumidifier that condenses out
the moisture. The chassis is made of stainless steel, which is
especially important in condensing units. The rotor is, as always,
washable, all energy is accumulated in the dry air. Aquasorb operates
at dew-points
below 0°C.
Rotor
Cassettes
Rotor cassettes are used when a standard dehumidifier is not suitable
or does not satisfy the customers' needs, e.g. air treatment units.
The rotor cassettes contains:
- Seibu Giken's unique SSCR rotor
- Rotor motor with transmission
- Sector seals
