FROM SEIBU
GIKEN DST
Seibu Giken DST
is certifi ed according
to ISO 9001.
About Seibu Giken DST
Established in 1985
A leading international supplier of desiccant dehumidifi ers
More than 40 representatives world-wide
Seibu Giken DST has just the dehumidifi er for you!
There is moisture everywhere. Damp air in the
wrong place can damage products and buildings
or reduce the effi ciency of a production pro-
cess. Dehumidifi ers from Seibu Giken DST AB
are your best means of avoiding such harmful
moisture.
There is a Seibu Giken DST dehumidifi er for all
applications from small portable units to large
dehumidifi ers, for e.g. the process industry. All
of DST’s units use the unique SSCR rotor from
Seibu Giken, Japan. A guarantee of high dehu-
midifi cation capacity!
DST’s dehumidifi ers are characterized by:
high level of operational reliability
low energy consumption
service-friendly design
The SSCR rotor from Japan is at the heart of every DST dehumidifi er
Seibu Giken in Japan manufacture the rotors
for all of DST’s dehumidifi ers. Thanks to our re-
search and development efforts, the SSCR rotor
has been at the leading edge of sorption tech-
nology for many years. The quality of the rotor is
crucial for a dehumidifi er.
Contact your nearest DST agent for more information!
There are agents in approximately 40 countries
all over the world at your service. DST is
now one of the world’s leading suppliers of
dehumidifi ers.

Incoming air.
Outgoing dry air.
Outgoing wet air,
condensed in certain cases.
Small dehumidifi ers
Stainless steel units. These dehu-
midifiers are used for purposes
such as dehumidification in stor-
ages, pump stations, laboratories,
hydropower plants and for water
damage restoration.
Mid-range dehumidifi ers
R-060BR and R-51R/-61R are stain-
less steel units used in fi elds such as
process industry, museum, archives,
warehouses, or in the event of serious
water damage.
The RZ series consists of four compact
units made of galvanised steel with
fans on the outside.Ideal for the proc-
ess industry, for example. Available
with pre- and post cooler.
Dehumidifi cation principles
The basic principle of sorption dehu-
midifi cation is that the rotating rotor
continuously adsorbs the moisture.
The moisture is discharged via an
independent wet air outlet.
Recusorb R operates using in-
tegrated heat recycling. During
the rotor’s regeneration (green),
heat is absorbed, and then
recycled in the “purge zone”,
where incoming air is pre-
heated and partly dehumidifi ed.
Energy consumption falls and
the dry air becomes both drier
and cooler compared to other
sorption dehumidifi ers.
Like Recusorb R, Recusorb DR
has heat recycling, but has a fan
for both the dry airfl ow and the
wet airfl ow. This makes instal-
lation simpler when you require
overpressure in the room to be
dehumidifi ed. This principle is
also suitable when you want to
achieve very low dew points.
The Consorb principle is nor-
mally used at low regeneration
temperatures, e.g. if you have
surplus heat or when dehumidi-
fying very damp air.
Frigosorb is a principle pa-
tented by DST. Frigosorb is
used in applications where it
is diffi cult to remove a wet air
airfl ow. Thanks to the heat
pump function Frigosorb is
very energy-effi cient, using
approx. 1/3 of the total energy
consumption of regular sorption
dehumidifi ers.
Aquasorb basically functions as
a Consorb but the wet air fl ow
is condensed in an air-chilled
condenser instead of being led
out. Thanks to the common
fan for dry air and cool air, all
energy is accumulated in the
dry air. Aquasorb has a high
dry airfl ow, which improves the
drying effect.
Econosorb combines a heat
pump with the sorption rotor
in a unique way, providing very
low energy consumption and a
low dry air temperature. Pro-
bably the most energy-effi cient
dehumidifi er on the market, with
approximately 1/4 of the total
energy consumption of regular
sorption dehumidifi ers. Econo-
sorb has both condensation and
wet air.

Control equipment
A good control system for dehumidifi cation in-
stallations will usually have a very short payback
period. DST offers a number of tried and tested
controls to meet the needs of various appli-
cations with regard to energy-saving, climate
control and monitoring. See DST’s separate
brochure for further information.
Choose between four different rotor from Seibu
Giken, all with unique qualities.

Flexisorb dehumidifi ers for industrial applications Flexisorb means fl exibility. The Flexisorb range
has been developed by DST to satisfy the varying
requirements of industry. Flexisorb units are
modular in their design, and have tremendous
potential to be adapted according to the specifi c
requirements of each application.
Econosorb – the most energy ef-
fi cient unit in the DST range. No
high temperature gain across the
process sector.
Dry air fl ow: 1 400–18 700 m3/h
Energy consumption: 0,4 kWh/kg*
Frigosorb – an energy effi cient dehu-
midifi er with built in condenser.
Dry air fl ow: 3 700–33 700 m3/h
Energy consumption: 0,6 kWh/kg*
Recusorb – embraces internal heat
recovery whilst being highly energy
effi cient.
Dry air fl ow: 900–61 100 m3/h
Energy consumption: 1,4 kWh/kg*
Consorb –suitable where there is a
wide temperature difference between
the process air and regeneration air.
Dry air fl ow: 1 000–61 100 m3/h
Energy consumption: 1,7 kWh/kg*
Flexisorb uses the Recusorb,
Consorb, Econosorb or Frigosorb
dehumidifi cation principles.
