Do
You Have A Water Problem With your Compressed Air System? You Need A Dryer!
All
Air Compressors produce water as a by-product.
Why air compressors put out water is a common question. The answer is
actually rather simple. Air always contains a certain amount
of water (actually water vapor) in it. This is what the
Meteorologists call relative humidity, the same thing that makes it rain
outside. In the simplest terms,
as air is compressed into a smaller volume, it has less and less ability to
hold this water vapor (a gas). Since the water vapor has nowhere else
to go, it condenses and forms liquid water. This
liquid water must be dealt with or it will flow throughout your system and
exit through your tools and get into your air-operated equipment, causing
all sorts of expensive problems.
This is why
a properly designed
air system has automatic drains that empty
accumulated water periodically and has an appropriate type of compressed air
dryer installed in the system. Now, if you think you have a properly
designed system and you still have a water problem, this is an entirely
different matter. There can be many causes for this issue. We
suggest that if you are experiencing water problems you should contact
Nebraska Pneumatics and let us help you solve your problem.
Refrigerant
Air Dryers are NOT the only type of air dryer available.
There are other types or air dryers commonly used, desiccant
air dryers and deliquescent air dryers.
They each have their use. The big question that dictates the type of
dryer you need is where you will be using your air. Will you be using
your air inside of a heated plant, in an unheated plant or a warehouse?
Do the lines run outside between buildings? Depending on the answers
to these questions, you may actually need one of the other types of dryers.
Desiccant dryers can dry air in extremely cold environments
as well as any environment that “defeats” the drying ability of a
refrigerant dryer. Deliquescent dryers have some of
the same attributes of the desiccant dryers (and at a lower cost!) but they
unfortunately, are messy to use. In a deliquescent dryer, the drying
agent, urea (salt), is consumed in the drying process. It is for this
reason that deliquescent dryers are rather uncommon. These
dryers can be a good choice in certain situations, especially where the
system temperature will get down to well below freezing or the dryer will
have to be outdoors. These dryers also don't require any electrical power to
operate either which can be a plus in some installations.
If
you have questions about which dryer type will serve you best, please
contact Nebraska Pneumatics. We will be happy to assist you in
choosing the dryer that is right for you.
