To obtain air without moisture directly from the
atmosphere to be used in industrial applications
is almost impossible. If moisture remains
untreated in the compressed air that is used in
industries it could affect the performance of air
used in the process and cause damage to machinery
that is sensitive to moisture. This article
outlines the advantages of using desiccant dryers
in industrial air drying processes.
The atmosphere is awash with water vapour in high
temperatures and lower temperatures. In the
summer months, the conditions in the Middle East
especially the coastal region like the UAE is
extremely humid and hot, with temperatures that
exceed 43 degrees Celsius (109 degrees
Fahrenheit) and humidity that is at over 90 per
cent. This has a profound effect on the amount of
water present as the atmosphere is compressed.
Disruptions and problems like corrosion of pipes
could result from water vaporization in pipes and
the equipment that is connected. To prevent this
from happening it is essential that the
compressed air be dried.

Deciding on the best dryer to deal with wet
compressed air is dependent on the demands and
tolerance levels of the equipment that makes use
of compressed air. There are a variety of air
dryers on the market but one of the most utilized
for applications that require a lot of attention
for the Middle East region is a desiccant air
dryer.
What is the Desiccant Dryer?
A desiccant dryer, also known as an absorption
dryer, is a type of industrial equipment which
makes use of desiccant substances to remove all
water in the air that passes through it. A
typical desiccant dryer utilizes a two-tower
configuration for a continuous air-drying cycle.

What does it mean by a Regenerative Desiccant air
Dryer?
"Regenerative" is a term used to describe a
"regenerative" is used to describe an industrial
desiccant dryer that can renew its desiccant by
reversed adsorptive processes. Regenerative
dryers typically are equipped with towers packed
with desiccant that allow water absorption and
material regeneration to happen simultaneously.
Twin Tower Compressed Air Dryers
Desiccant dryers with twin towers are dual
desiccant dryers that continually switch between
absorptive as well as regenerative modes.
Indicators determine the degree of saturation of
the water in each tower and automatically switch
to regenerative mode as needed.
It's the Ideal Method for Compressed Air Drying
Utilizing the highest-quality activated alumina
desiccant by Ingersoll Rand gives you better
control over the conditions of your system, such
as temperature, pressure, and levels of moisture.
It also assists in achieving low-pressure dew
points that range from -40degF up to 100degF
(-40degC from -70degC) ensuring the most dry and
clean air and maximizing the performance of
equipment and the life of your equipment.

How Does Activated Alumina Function Within an Air
Dryer?
The adsorbent, which is the principal component
of the air dryer, is subjected to constant
pressure as well as water vapour and heat shocks.
These can easily result in mechanical failure as
well as medium defacement. This reduces the
effectiveness of the adsorbent. Because activated
alumina replaces silica gel as the primary
adsorbent, a variety of properties including
constrictive strength as well as resistance to
water absorption are greatly improved to a
superior degree if there is no "renewable energy
use" and other related activities occur. Certain
aspects like activated alumina treatment and
compressed air's dew point, stability of the
temperature of -40 degrees Celsius, and a
time-to-life of three to two years are all
guaranteed in the process. Compressed air that
comes from the rear of the compressor is a type
of supersaturated compressed air which contains
condensate. The dryer is not influenced by a tiny
amount of condensate. If a gas water divider and
filter are not installed on top of the dryer or
if a significant amount of condensate water
enters the adsorption tower due to unintentional
causes the adsorption can decrease and the
temperature of the dew point will increase
dramatically. The adsorbent may disintegrate into
powder in extreme conditions, leading to dust
being discharged from the muffler or obstruction
of the dirt filter in the rear, in addition to
the requirement of replacing the adsorbent. In
dryers using compressed air 1/8 inch (2-5
millimetre) activated alumina beads is the most
utilized. The 1/4" (5-10 millimetre) activated
alumina is commonly used as a pre-bed to support
large desiccant beds or as a buffer in silica gel
bedding. The 3/16 (3-5 mm) (5-10 5-10 mm) beads
are used for situations where the pressure drop
or surface requirements are between 1/8 or 1/4''
materials.

Active Alumina Desiccant Features
The beads are uniform and smooth minimize
pressure drop and ensure that the entire
desiccant bed. Abrasive-resistant reduces
dusting during loading, transport, and service
life. Reduces pressure drop. Strength of High
Crush to allow for faster tower load and
efficient use of desiccant. Large capacity for
adsorptive Reduces the initial cost as well as
operating expenses and energy consumption. Long-t
erm service duration provides longer service
intervals, ranging from 2 to 5 years. Dusting is
low and prolongs the service intervals The
dryer's filter prevents its after-filter from
getting blocked and delivers better-quality,
clean air.

When do I have to replace the Desiccant?
Desiccant lifespan varies based on the use. The
greater the humidity and flow within your dryer
the more frequently your desiccant must be
replaced. Here are a few indicators to help you
determine when you should change the desiccant
beads inside your dryer. The desiccant beads are
coated with oil which makes them ineffective at
effectively adsorbing water. The presence of oils
or contaminants in the dryer. The desiccant
appears discoloured. Desiccant tests are advised
every six months as a part of the routine
maintenance. But, as the activated alumina
builds up water as time passes, it eventually
reaches an equilibrium point. Regeneration is
required to maintain the efficiency for the
desiccant. Regeneration typically involves
redirecting some of the dry air from drying
towards the desiccant bedding or using direct
heat to remove the water away from the particles.
The Activated Alumina is distinguished by the
ability to undergo multiple regeneration cycles,
making it a more economical option for drying
compressed air systems. Each method of air
drying has each method's benefits and is
according to criteria like the necessary dew
point and the volume of air that requires drying,
energy considerations and the requirements
specific to an industry. Whatever the method the
importance of drying compressed air for the
compressed air system, in conjunction with the
importance of activated alumina's part to this
procedure, can't be overstated.
