Process Explanation:
Weiber commercial series dehumidifier removes moisture
from the air, thus lowering the humidity. It does this by
condensing water onto a cold surface. A fan is used to speed
up the process. It blows warm air onto cold metal coils, and the
resulting water drips into a water collector. The resulting cold
air is then passed over warm coils to bring it back to room
temperature. The air is then reheated and sends back to the
room.

Application
Dry Air Storage (Multi Purpose)
In dry air storage our dehumidifier keeps the relative humidity
at the desired level all year round regardless of the
temperature. Basic dry air storage only requires an un
insulated, reasonably airtight, building fitted with a
dehumidifier. Steel and other metals, wood, paper, pulverized
products, military equipment are just a few examples of items
possible that can be stored safely and at low cost.

Production Facilities (Pharmaceutical)
Weiber dehumidifiers make it possible to produce
pharmaceutical products all year round in a controlled dry
atmosphere. These dehumidifiers increase production
capacity in spray dryers and fluidized beds that are used, for
example, in the food industry. Breweries can avoid mould and
condensation on cold surfaces by using dehumidifiers
Archives
Archives for photographic film must be kept at low
temperature and at low relative humidity, typically + 2 ºC, 30%
RH. A controlled climate with stable relative humidity is also
vital to prevent art collections, old documents, textiles, books
etc from being damaged by the ravages of time.

Power Plants And Buildings
Being able to supply dry air inside industrial facilities and
buildings is an important capability. Power plant boilers,
piping, steam condensers, turbines and bridges are examples
of dry air corrosion protection methods. Buildings that have
suffered flooding or moisture damage can often be made fully
functional again after drying out with dry air.

FAQ
What is humidity?
As most people already know, humidity is defined as the
amount of moisture in the air. Relative humidity is a way to
measure the amount of humidity present based on the
maximum amount of humidity the air can hold.
Basics of humidity
The amount of moisture that air can contain is roughly based
on its temperature. Cold air can hold, less moisture and warm
air can hold more. In the winter time your house is surrounded
by cold air that doesn't hold as much moisture, so the
conditions inside your home naturally try to match their
surroundings. This is why your house is typically dry in the
Commercial Dehumidifiers
ACMAS TECHNOCRACY PVT. LTD.www.measuring-meters.com | www.acmasindia.com | www.scientificlaboratoryequipments.com
winter (unless of course you are using a humidifier to add
moisture). The warmer summer air can hold more moisture,
and therefore your house also tends to have much higher
humidity levels in the summer time.
How do you calculate relative humidity?
How does this help to determine relative humidity? Any
temperature of air has a maximum amount of moisture it can
hold. The relative humidity is expressed as a percentage of
the current moisture level relative to the maximum moisture
level for the current temperature. For example, when the
inside temperature of your house is 68° F then 1 cubic meter of
air can hold 18 grams of water (called saturation, or 100%
relative humidity). If the air contains 9 grams of water per
cubic meter, then the relative humidity is 50% (9 / 18 = 50%).

How Dehumidifiers Work
Many people understand what dehumidifiers do, but not many
people understand how dehumidifiers work, and more
importantly what factors will help or hinder the dehumidifier
you choose.
The Basics of Dehumidifier Operation
We've all witnessed water forming on the glass of a cold drink.
The same principle is used by dehumidifiers to extract
moisture from the air. When warm air is exposed to a cold
surface, water is pulled from the air and collects on the colder
surface. This is called condensation. A dehumidifier uses a
fan to pull air across a metal coil that is cooled by a
compressor . Once the water is extracted from the air and
collected on the cold coils, the air is re-heated and exhausted.
The water that was collected falls into a reservoir where it can
be drained.

How Air Movement Affects Dehumidifiers
Now that you understand the basics of dehumidifier
operation, you need to also understand what characteristics a
dehumidifier must have to work well. For starters, a
dehumidifier must have a fan of some sort that actively draws
air into the dehumidifier, across the cold coils, and back out
again once the moisture has been extracted. The amount of
air a dehumidifier can move is measured in CFM, or cubic feet
of air per minute. The more CFM a dehumidifier can move, the
better job it can do removing moisture from larger spaces.
Without an effective air mover, the dehumidifier would only
remove air from the space immediately surrounding the unit.
Smaller portable dehumidifiers move less air and are typically
best suited for single-room dehumidification. Large whole
house units are equipped with larger fans and can extract
moisture from much more air, and therefore much larger
spaces (like an entire basement or crawlspace).

How Relative Humidity Affects Dehumidifiers
Dehumidifiers have an easier time extracting moisture when it
is readily available in the air. Dehumidifiers can extract much
more moisture when they are running in a moist environment.
It is much more difficult for a dehumidifier to remove moisture
as you lower the relative humidity. So, if you are trying to bring
a moist area (relative humidity of 70% or more) down to a
normal level of 50%, many whole house dehumidifiers can
accomplish that task. If, however, you are trying to get your
relative humidity down to 20% you'll need a much more
powerful dehumidifier for that task.

Why Does CFM Matter?
What is CFM?
CFM stands for Cubic Feet per Minute, and is used to measure
how much air a fan or piece of equipment can move. For
dehumidifiers, CFM is important because moisture can only
be extracted from air that can be moved through the
dehumidifier. Simply put, if your dehumidifier cannot move
any air (CFM = 0), then it cannot extract any moisture.
How much CFM do I need?
The CFM needed is based the square footage and level of
humidity in the space you want to dehumidify. Technically
we're interested in the cubic footage (square footage x celing
height), which will determine how many cubic feet of air that

we need to cycle through the dehumidifier. Determining the
level of humidity will indicate how many times the air should be
cycled through the dehumidifier every hour (know as ACH, or
Air Changes per Hour). The higher the relative humidity the
more often that the air needs to be cycled through the
dehumidifier.
If you have a hygrometer (an inexpensive device that can
measure the relative humidity), you should be able to test the
humidity levels in your basement or crawlspace. If you do not
have a hygrometer or any other way to get a fairly accurate
measurement of the relative humidity, you can typically come
up with a good estimate from the table below.
To calculate the minimum CFM that your dehumidifier should
have, take the cubic feet of your basement or crawlspace,
multiplied by the number of times per hour that air should be
changed (ACH), and then divided by 60 minutes. The
resultant number should give you the CFM that your
dehumidifier should have. Below is an example to calculate
CFM:
Commercial Dehumidifiers
ACMAS TECHNOCRACY PVT. LTD.www.measuring-meters.com | www.acmasindia.com | www.scientificlaboratoryequipments.com
4. 65% relative humidity = 3 air cycles per hour
5. 1,000 ft² * 7 ft ceilings = 7,000 ft³
6. 7,000 ft³ * 3 ACH / 60 minutes = 350 CFM
The CFM calculation should serve as a guide for sizing your
dehumidifier. If you find that your suggested CFM is much
higher than any dehumidifier you can find, you can always
install more than one unit to increase the dehumidification. If
the dehumidifier you choose has a higher CFM rating that
what you need, then the dehumidifier will run less frequently to
achieve the desired relative humidity levels (in other words, it's
OK to get a larger dehumidifier than you need).

How much will my dehumidifier be able to lower the
humidity?
A) That will depend on a lot of things. Most importantly, the
temperature in your room will determine the minimum
humidity level you will be able to achieve. With most
dehumidifiers the air comes out at around 30% humidity. At 70
degrees and higher it is possible to reduce the humidity to
35% to 40%. As the temperature goes below 70 degrees and
down into the 50's this will rise to 60 %. If the humidity reached

is not as low as you want, you can heat the room or raise the
dehumidifier off the floor where it is coldest. Since heat rises
the air temperature will be higher as you elevate it towards the
ceiling. This will enable you to further lower the humidity. There
are other factors affecting how low you can bring the humidity
level, such as the size of the area you are dehumidifying,
construction of the room, and the area of the country where
you live.
