The
Original "Honeycomb" Wheel.
A Munters Innovation |
|
Our dehumidifiers uses
a desiccant to remove moisture from the air. The
desiccant is impregnated into a wheel made up
of a corrugated ceramic composite material. During
operation the wheel rotates continuously through
two air streams separated by seals.
The desiccant removes moisture from the process
air thereby drying (dehumidifying) it. Meanwhile
desiccant which is moving in the heated reactivation
air stream gives up the moisture it had earlier
picked up from the process air. The moisture is
then discharged outdoors together with the wet
air.
|
 |
| The desiccant is thus
dried up (reactivated) in preparation for moisture
removal when it rotates into the process air stream
again. The result is a consistent humidity level
of the dry air stream as it leaves the desiccant
wheel. The wheels are built to operate 24 hours
a day, 7 days a week for years. |
|
| |
| Advantages of the rotary
Honeycomb design. |
|
- Very lightweight and porous structure.
- Different kinds of desiccant (Licl, titanium gel,
molecular sieve) can be loaded into the structure,
which allows a wheel to be tailored for specific
applications.
- Low dewpoint and high capacity can be achieved.
- Energy efficient.
- Simple, reliable and easy to maintain.
- Reduced air pressure resistance.

| Applications |
|
The Applications of Munters dehumidifiers are too
wide to list exhaustively. In view of that we list below
the main areas of requirement for our equipment and
most applications are linked to one or more of these
areas in one way or the other.
We hope that you can identify your problems with one
of the following.
Preservation
against corrosion
Steel components does not corrode in environment of
40% relative humidifty (RH) and below. Very little corrosion
occurs between 40 to 50%. Thus, where corrosion present
a problem in downgrading of material / equipment quality
or cause damages, the solution is to control the RH
with a dehumidifier.
Preservation against mouldiness,
fungus and rot
All materials are hygroscopic to various degree. The
amount of moisture in materials increases with increased
RH of the environment. High moisture content in materials
encourages growth of mould, fungus and bacteria which
results in rotting of the materials. Control RH at
60% or below with our dehumidifier to avoid these
damages.
Prevents caking up of powders
Too much moisture in powders causes them to cake up
which prevents free flow of the materials. By maintaining
the powder in dry air conditions caking will not occur.
Prevents product rejects due
to vapourisation of residual moisture in raw materials
In the production of products where raw materials
are heated to molten state the vapours from residual
moisture causes weakness and poor finish by forming
bubbles in the finished products. For laminates the
vaporisation of this moisture causes delamination.
Removing the residual moisture from the raw materials
removes these problems.
Drying of materials at low
temperatures
Products which are sensitive to high temperatures
needs to be dried with very dry air. The desiccant
dehumidifier can provide such dry air.
Prevents short circuiting of
dormant electrical components
The insulation of electrical cables breaks down when
they are kept dormant for long period in an environment
of high relative humidity. This causes short circuiting
when the eletrical components are put in operation
again. Enveloping the components in dry air gets rid
of such problems. |
