Desiccant Dehumidificationvs Mechanical Refrigeration
Both Desiccant Dehumidifiers and mechanical refrigeration systems can
remove moisture from the air, so the question is - which type is best suited for
a given application? There really are no simple answers to this question but
there are several generally accepted guidelines which most dehumidifier
manufactures follow :
• Both desiccant-based and refrigeration-based dehumidification systems
work most efficiently when used together. The advantages of each
compensate for limitations of the other.
• Refrigeration-based dehumidification systems are more economical
than desiccants at high temperatures and high moisture levels. In
general, mechanical refrigeration systems are seldom used for
application below 45% RH. For example, in order to maintain an outlet
condition of 40% RH, it would be necessary to bring the coil temperature
down to -1°C (30°F), which results in the formation of ice on the coil and a
reduction in moisture removal capacity. Efforts to prevent this (defrost
cycles, tandem coils, brine solution, etc) can be very cumbersome and
expensive.
• Desiccant-based systems are more economical than refrigeration
systems at low temperatures and lower moisture levels. Typically, a
desiccant dehumidification system is utilized for air application below
45% RH down to less than 1% RH. Thus, in many applications, DX or
chilled water pre cooling coil is mounted direct at the dehumidifier inlet.
This design allows for removal of much of the initial heat and moisture
prior to entering the dehumidifier where the moisture is further reduced.
• The difference in the costs of electrical power and thermal energy (i.e.
natural gas or steam) will determine the ideal mix of desiccant to
refrigeration-based dehumidification in a given application. If thermal
energy is inexpensive and the power costs are high, a desiccant based
system may be more economical to remove the bulk of the moisture from
air. If power is inexpensive and thermal energy for reactivation is costly, a
refrigeration-based system may be the most efficient choice.
Using Desiccant to Dry Air
A simple straightforward way to obtain dry air is to use desiccants - that is,
adsorbents or materials that have a natural affinity for water. A desiccant is
able to take up the additional moisture given up by the air without swelling. So
an air stream can pass through a desiccant and become significantly drier
without elaborate cooling, compression, or other complex systems or
controls. After the drying task is complete, the desiccant is dried using hot air
in a process called regeneration, and is ready to dry more air.
A Bry-Air Desiccant Dehumidifer utilizes only a small amount of desiccant at
any one time and constantly regenerates as part of a continuous cycle. This
simple equipment is manufactured in many sizes, from very small to very
large to meet various dry air requirements.
An added feature of the Bry-Air Dehumidifier is its ability to function equally
well at extremely low to very high levels of humidity with no regeneration
problems and no changes in cycle control. Its versatility in performing in any
type of application is unique among the methods of drying air.
The new EcoDry dehumidifiers incorporates the BrySmart EMS (Energy
Management System) technology. Unlike the present product technologies ®and control systems, BrySmart EMS, is a microprocessor-based, cutting-
edge dehumidification control system, based on inputs of several key
parameters, processing these with in-built algorithms and modulating various
devices/components in the system to optimize energy usage based on
varying ambient conditions and internal sensible & latent loads.It is possible
for existing installations to save upto 45% energy by retrofitting their existing
installations with an EcoDry BrySmart EMS. This results in less energy
consumption and hence lower electricity bills.

The Nature of Water Vapour
Consider two closed rooms adjacent to one another. If the partial pressure of
the water vapour in room #1 is greater than the partial pressure of the water
vapour in room #2, then the water vapour will travel through the wall into room
#2 The amount of water vapour transmitted (called permeation) will depend
on the materials and quality of construction of the wall.
Let’s take this hypothetical example a step further. If the absolute humidity of
the air in room #1 is greater than that of the air in room #2, then the water
vapour pressure will be higher in room #1. Therefore, when drying room #2,
the problem of water vapour coming through the wall from room #1 must be
considered. A vapour barrier cannot completely eliminate the permeation and
infiltration of water vapour, but it can greatly reduce it.
The choice of water vapour barrier is based on the degree of dryness required
in the controlled space; the efficiency of the equipment being used for drying;
and the cost of construction.
Commercial vapour barriers, moisture resistant construction material, paints
and other coatings, offer a variety of design alternatives. Manufacturers of
vapour barrier materials can supply information on their products.
Construction of Controlled Spaces
1. Any vapour barrier must be continuous, without breaks or tears.
2. All lap joining must be tightly closed. (This is particularly critical when
mechanical or caulked joints are used).
3. Insulation between vapour barrier can be a potential problem. If
construction occurs in humid weather, moisture can be “sealed in
between the two vapour barriers.
Sealed-in water vapour will travel into the controlled space and impose
an extra drying load on the drying equipment. This extra load lasts only
until the insulation dries out, but meanwhile humidity control is difficult.
If a heat source is present (even heat from the sun), serious damage can
be caused by the expanding trapped vapour. There have been cases
when so-called “non-permeable” material have split open at a joint
because of vapour pressure. Examples include a floor or tiled wall that
has literally lifted from its mounting surface because the surface was wet
during the application.
4. Final inside vapour barriers should be applied after the enclosed area has
been dried. Drying equipment should be used to withdraw as much
moisture as possible before the final barrier is applied. Of course, without
a barrier in place, equipment cannot dry the area to design specifications,
but a significant amount should be removed before all the vapour barrier
material is in place.(Although this strategy is not included in most
industrial planning suggestions, the concept of drying the structure
before applying the final vapour barrier is a precaution that is often
overlooked and can help prevent problems associated with trapped
water vapour).
5. All doors, service or personnel, should be weather-stripped or air locked
through vestibules if the desired conditions warrant it. Any crack or
opening around a door will admit water vapour.
6. When a conveyor opening (or similar element) is used a strip curtain,
shroud, or tunnel will reduce the migration of water vapour into space.

vapour in room #2, then the water vapour will travel through the wall into room
#2 The amount of water vapour transmitted (called permeation) will depend
on the materials and quality of construction of the wall.
Let’s take this hypothetical example a step further. If the absolute humidity of
the air in room #1 is greater than that of the air in room #2, then the water
vapour pressure will be higher in room #1. Therefore, when drying room #2,
the problem of water vapour coming through the wall from room #1 must be
considered. A vapour barrier cannot completely eliminate the permeation and
infiltration of water vapour, but it can greatly reduce it.
The choice of water vapour barrier is based on the degree of dryness required
in the controlled space; the efficiency of the equipment being used for drying;
and the cost of construction.
Commercial vapour barriers, moisture resistant construction material, paints
and other coatings, offer a variety of design alternatives. Manufacturers of
vapour barrier materials can supply information on their products.
Construction of Controlled Spaces
1. Any vapour barrier must be continuous, without breaks or tears.
2. All lap joining must be tightly closed. (This is particularly critical when
mechanical or caulked joints are used).
3. Insulation between vapour barrier can be a potential problem. If
construction occurs in humid weather, moisture can be “sealed in
between the two vapour barriers.
Sealed-in water vapour will travel into the controlled space and impose
an extra drying load on the drying equipment. This extra load lasts only
until the insulation dries out, but meanwhile humidity control is difficult.
If a heat source is present (even heat from the sun), serious damage can
be caused by the expanding trapped vapour. There have been cases
when so-called “non-permeable” material have split open at a joint
because of vapour pressure. Examples include a floor or tiled wall that
has literally lifted from its mounting surface because the surface was wet
during the application.
4. Final inside vapour barriers should be applied after the enclosed area has
been dried. Drying equipment should be used to withdraw as much
moisture as possible before the final barrier is applied. Of course, without
a barrier in place, equipment cannot dry the area to design specifications,
but a significant amount should be removed before all the vapour barrier
material is in place.(Although this strategy is not included in most
industrial planning suggestions, the concept of drying the structure
before applying the final vapour barrier is a precaution that is often
overlooked and can help prevent problems associated with trapped
water vapour).
5. All doors, service or personnel, should be weather-stripped or air locked
through vestibules if the desired conditions warrant it. Any crack or
opening around a door will admit water vapour.
6. When a conveyor opening (or similar element) is used a strip curtain,
shroud, or tunnel will reduce the migration of water vapour into space.

Production Rooms For Lithium Battery
Manufacturing
The relative humidity of the air is a critical factor in the manufacture of lithium
batteries. Pure lithium metal is extremely sensitive to water, and even tiny
amounts of water vapour in the air in the manufacturing areas will significantly
affect the quality of the batteries produced. When water vapour in the air
contacts lithium metal, a chemical reaction occurs that forms lithium
hydroxide and hydrogen gas. The reaction is exothermic, so the lithium metal
becomes hot. The lithium hydroxide on the metal surface decreases the
capacity of the battery. In addition, any moisture that is sealed inside the
battery will react after the battery is completed. The hydrogen gas generated
will cause the battery to swell, further reducing the battery capacity and useful
life. In extreme cases the hydrogen gas can cause the battery to rupture,
creating a safety hazard.
To avoid these problems, the production rooms are designed and built to be
extremely vapour-tight and the rooms are typically maintained at -40 deg.C
dew point humidity, which is the moisture content of 0.08 grams water vapour
per kilogram of air. To maintain this humidity level, the air is typically delivered
to the production rooms with a moisture content of 0.01 grams water vapour
per kilogram of air.
Bry-Air provides desiccant dehumidifiers that are specially designed to
reliably deliver air at these extremely low humidity levels while still
maintaining good operating efficiency.
The battery manufacturing process releases traces of hydrofluoric acid which
is carried back to the dehumidifier in the return air. This slowly reacts with the
desiccant media gradually reducing its drying capacity. Typical desiccant
rotors require replacement after about 12 to 18 months of operation to
maintain acceptable room humidity. However, Bry-Air has developed a
special desiccant media that is more resistant to traces of acid vapour in the
air. In lithium battery production applications, the Bry-Air media will usually
maintain acceptable room humidity for about 5 years. This substantially
reduces the maintenance costs of Bry-Air units compared to units from other
manufacturers.

Adsorption Chiller
Design and Operating Principle
The moisture is adsorbed in the dehumidification sector by the fluted, metal silicate desiccant synthesized rotor. The rotor is dried in the reactivation sector with a stream of hot air, which carries the moisture away and is usually exhausted outside.
Following the reactivation process, the adsorption sector is again ready to adsorb the moisture. Thus, the two processes of "moisture adsorption" and "reactivation" are taking place with separate air flows continuously and simultaneously. Positive sealing between chambers prevents mixing of the process and reactivation air stream.
Outstanding User Benefits
• Reduced Foot Print
• Increased Performance
• Lowest Volume/Weight per CMH
• Simple & easy to install
• Light weight, and can be installed above the false ceiling

EcoDry at the heart of it
The EcoDry Dehumidifying rotors are the result of many man-years of in-depth study and research on countless permutations and combinations of substrates, desiccants and chemical processes. Every parameter has been considered to maximize performance, durability and applicability.
Advantage with EcoDry inside
• Adsorbent, non-toxic, non-flammable, fully water washable.
• In-situ synthesized metal silicate desiccant on an inert inorganic fibre substrate.
• Active desiccant 80% of the media weight, so as to ensure high performance and minimal heat carry-over.
• Rotor is non-flammable. The net organics in the honeycomb media less than 2%.
• Special edge hardened media surface to ensure a smooth surface and long life of both the media and the air seals.
• Rotor perimeter flange extend media and seal life.
• Rotor incorporates robust structure for industrial quality, durability and easy serviceability.
TMBryCool 500
The BryCool 500 compact dehumidifier is another energy efficient compact
dehumidifier from Bry-Air. BryCool accomplishes the task of providing cool
dry air for any enclosed facility which requires desiccant assisted drying
capability in a compact package. The unit uses the heat dissipated in
refrigeration cycle for regenerating the desiccant rotor. This leads to
substantial savings as no additional heat source is required to regenerate the
desiccant rotor. BryCool operates cost effectively because all the energy
required for the operation is coming from the integrated refrigeration unit
cooling the inlet air. It is ideal for facilities where human comfort is also
required along with the dehumidification.

FLB Series
The Bry Air Fluted Large Bed Dehumidifier FLB series is a one-stop source for total precise environmental control. Bry-Air can design, engineer and package the dehumidifier with :
• Pre and / or after -cooling coils.
• Bye -pass ducting and mixing chamber
• Volume controls and filter elements
• Upgraded fan for total system air to provide complete environmental cont ro l in a s ing le package for any industrial application.
How does it work?
Following the reactivation process, the adsorption sector is again ready to adsorb the moisture. Thus, the two processes of "moisture adsorption" and "reactivation" are taking place with separate air flows continuously and simultaneously. Positive sealing between chambers prevents mixing of the process and reactivation air stream.
Key Features
• FLB comes with a high performance EcoDry Metal Silicate Flute Desiccant Synthesized Rotor.
• It is manufactured to the highest consistency, reliability and ecology standards.
• Rotor media, is 80% by weight adsorbent, is non-toxic, non-flammable and fully water-washable.
• Manufactured with state-of-the art CNC machine tools
• Easy to install, operate and maintain
• High efficiency & reliability.
www.bryair.com 4342
Tray Dryer for Drying Seeds and Agro Products
• The Bry-Air Tray Dryers and Seed Storage Systems dry and preserve
seeds to maintain maximum product quality and germination yield.
• Seeds need to be preserved for short term and long term for future use
..replanting as well as research. Seed ageing and ultimately death occurs
due to time. However, it is possible to ensure long survival of seeds by
controlling temperature and relative humidity. Reduction in temperature
and moisture content ensures increased seed life.
• Seeds can be preserved for long period by lowering the moisture content of
seeds to around 5%.This is achieved by drying the seeds. Without
desiccant equipment, seeds must be dried at elevated temperatures which
destroy their germination potential.
• Bry-Air Tray Dryers, based on the state-of-the-art Desiccant
Dehumidification Drying Technology, dry the seeds to the required level in
approximately eight (8) hours without affecting their quality.
• Seeds dried prior to storage can regain moisture and suffer damage if not
stored under controlled conditions. Dried seeds can be preserved for years
in dehumidified stores without loss of germination potential.
• Bry-Air Dehumidification based Tray Dryers and Storage Systems are
being used extensively world over by commercial and plant breeding
organisations including the FAO.

desiccant equipment, seeds must be dried at elevated temperatures which
destroy their germination potential.
• Bry-Air Tray Dryers, based on the state-of-the-art Desiccant
Dehumidification Drying Technology, dry the seeds to the required level in
approximately eight (8) hours without affecting their quality.
• Seeds dried prior to storage can regain moisture and suffer damage if not
stored under controlled conditions. Dried seeds can be preserved for years
in dehumidified stores without loss of germination potential.
• Bry-Air Dehumidification based Tray Dryers and Storage Systems are
being used extensively world over by commercial and plant breeding
organisations including the FAO.

Flexible Barrier Storage (FBS) System for
Military Hardware
The FBS system protects
military equipment from
corrosion and from the
effects of humidity, salt,
pollutants, dust and insects.
It also protects equipment
from effects of ultra-violet
rays of the sun on metal,
rubber, paint, canvas, etc.
Damages caused by micro-
organisms such as fungi and molds are avoided. Flexible Barrier Storage
System (FBS) are employed and adopted by the Army, Navy and Air Force all
over the world to check the elements of destruction - corrosion, rot and mildew
and for preservation of hardware equipment and storage of active-status
material.
The Flexible Barrier, of the Flexible Storage Systems (FBS), as it is called,
consists of a reusable cover, which is resistant to moisture, oil, bacteria,
insects, rodents, etc., a humidity sensing device and a desiccant
dehumidifier.
This system of preservation is very versatile, more practical and technically
superior to any other system of preservation in the world. It assures flexibility
and mobility in choice of storage sites and eliminates the need for storage
sheds, reduces manpower costs and is easy to maintain even by unskilled
personnel. The high degree of preservation achieved through this
dehumidification system enables rapid reactivation of the defense
equipment. Being mobile, it can move with the troops and can be installed on
site whenever required, on any terrain.

Air-to-air rotary heat exchanger for industrial and process air exhausts
Bry-Air's BryXchange is an air to air rotary heat exchanger which recovers energy from high temperature exhaust air. Considerable high temperature air is generated in Kilns, vens and Furnaces which goes waste. Through BryXchange, this sensible waste energy can be recovered from the exhaust air and transferred to low temperature supply with efficiency of upto 75% energy.
Principle of working
BryXchange rotor is installed between the high temperature exhaust air and supply air stream. As the rotor slowly rotates, sensible heat of high temperature exhaust air is carried over by the rotor to the low temperature supply air.
Design and structure of BryXchange
The BryXchange rotor has a fluted media, fabricated with material having a high heat carrying capacity, which rotates between two side-by-side ducts: one a low temperature supply air duct, the other a hot temperature exhaust air duct. The axis of the rotor is located parallel to, and on the partition between, the two ducts.
General features
• Stainless steel, double walled, insulated casing.
• Sectorized Wheel for ease of installation and maintenance.
• Designed for very slow rotational speed of around 8-10 RPM.
• Manual cleaning system for media cleaning.
• Heat-stabilised external bearings with teflon gasket.
• Smooth surface to ensure minimum vertical runout.
• The rotor is made of alternate flat and corrugated foil of very uniform pitch and height.
• Rotor depth 200mm.
• Substrate-Aluminised steel or Stainless Steel foil
• Split casing for larger sizes.

Gas Phase Filtration
The Bry-Air EcoScrub Gas Phase Filtration not only cleans the
contaminated air of suspended particles and corrosive gases but also
eliminates odour, making the working environment healthy for you and your
equipment.
How does it work
The process of purification is simple. The contaminated air first passes
through prefilters which trap the suspended particles, and then through the
required chemical media beds, which chemically destroy or retain any
remaining gaseous impurities. The chemical media can be activated carbon
and / or activated alumina impregnated with proprietary chemicals, used
alone or in combination – depending on the types and concentrations of the
impurities present in air stream. EcoScrub Systems are designed to operate
and maintain contaminant gas levels at 1ppb (parts per billion) or less.
Introducing the Adsorption Chiller, based on an innovative green technology, and the first of its kind in India.
The Bry-Air Adsorption Chiller is based on an advanced green technology using inert Silica Gel(adsorbent) and Water (refrigerant) pair. It has unbeatable advantages like ultra-low electricity consumption, negligible noise and vibration, life expectancy of more than 20 years, negligible maintenance, etc. It is a first ever product being launched in India to tap the abundant low grade waste heat available in process industries and use it for process cooling and air conditioning (HVAC). This eco friendly solution cuts down CO2 emissions and reduces energy expenses.
It is ideal for process industries like Power Plants, Food processing, Chemical Manufacture, etc and for commercial areas like office, buildings, hotels, malls etc.
