The World Leader In Desiccant Dehumidification

Our DehumidificationTechnology

When you load your camera with 35mmphotographic film, you are probably usinga product manufactured with the help ofour dehumidifiers. And next time you hearof a friend who has had a cardiac pace-maker implant, or when you enjoy finechocolates, or when you find relief froman upset stomach by using an effervescenttablet, you can be reminded of the subtlebut important role played by our equip-ment in the daily lives of hundreds of mil-lions of people. All Cargocaire dehumidi-fication equipment is manufactured in the

USA under ISO 9001:2000 certification.Our equipment removes moisture from

air by using a desiccant a material whicheasily attracts and holds water vapor.Desiccant dehumidifiers are especially

well-suited to removing moisture from airat low temperatures and low humidities.

In our units, the desiccant is impreg-

nated into a corrugated ceramic compositematerial which is formed into a wheel. Airpasses easily through the flutes, contacting

the desiccant. The wheel rotates slowly(6 to 10 rph) between two air streams.The incoming process air stream thelarger one gives off its moisture to thedesiccant. The process air is dry as itleaves the wheel. The humidity-laden

wheel rotates slowly into a second, smallerairstream which has been heated. Thissmaller exhaust airstream called the reac-tivation air warms the desiccant. The

warmed desiccant gives off its moisture,which is then carried away by the reactiva-tion air. The newly dried desiccant mate-rial is rotated back into the process air,

where it absorbs moisture once again.The desiccant support structure, which

we call the HoneyCombe wheel, is quiteremarkable. It can hold more than its own

weight in water vapor. Our wheels arebuilt to collect and release water six times

every hour, 24-hours-a-day, 7-days-a-week,for years. This durability is one reason ourdehumidifiers require so much less main-

tenance attention than other air condition-ing system components like compressorsand controls.

The rotary desiccant wheel was pio-neered in Cargocaire dehumidifiers. Weare the company which invented the firstgeneration of wheels in 1958, and morethan 100,000 units have been placed inservice to our customers all around the

world. Over the years, we have developedmany different types of desiccant wheels(see page 3) which allow us to optimizeour dehumidifiers to meet a broad spec-trum of customer needs.

Munters: An InternationalCompany with a Tradition

of InnovationCargocaire Engineering Corporation

was founded in 1939 by CommanderOliver Colvin, USN, to providea solution to the costly problemof cargo deterioration caused byhumidity. That focus gave the com-pany its name. After World War II,Commander Colvin expanded opera-tions from cargo ships to militarystorage, and then into industrial usesfor dehumidification such as phar-

maceutical and electronics manufac-turing. In the late 1950s, the R&Ddepartment of Cargocaire began acooperative development program

with Carl Munters, the Swedish-borninventor of the absorption refrigera-tor and foam-board insulation. Theprogram resulted in the introductionof the HoneyCombe wheel, a majoradvance in dehumidification tech-nology which continues to lead theindustry today.

After Commander Colvin retired,

the Munters and Cargocaire com-panies were merged, and theycontinued to expand operationsthroughout the world. Today, thecompany operates 11 manufacturingplants and has offices in 25 countries.Munters Corporation produces prod-ucts as diverse as advanced VOC pol-lution control equipment, gas clean-ing media, humidification media, as

well as HoneyCombe dehumidifiersand Integrated Custom Air Handler(ICA) systems.

We pioneered the use ofdehumidification equipment for

warehouses, active-duty militaryequipment, lithium battery manufac-turing and even supermarkets, wherereduced humidity helps refrigerationsystems operate more efficiently. Ourequipment also helps protect thecultural heritage of humankind bypreventing deterioration of ancientEgyptian artifacts in Cairo and the

photographs of the Apollo moonlanding in Houston, Texas. We havea tradition of innovation and eagerpursuit of sound technical solutions

to challenging problems.Call us at (978) 241-1100 or(800)843-5360, send us a FAXat (978)241-1214 or e-mail us atdhinfo@munters.com. We lookforward to serving your needs as wehave done for our customers for overhalf a century.

HPX Desiccant

Cargocaires unique HPX wheel is an

adsorbent that provides very low dew

points (-70F and lower). This desiccant

is used under the advice of a Cargocaire

engineer for specialty applications.

Molecular Sieve

In very dry environments, zeolite des-

iccants are ideal. In return for a some-

what larger investment in reactivation

energy, they remove moisture from even

the warmest, driest airstreams. When your

application requires humidity control below 10%

relative humidity, or when hot air must be dehumidi-

fied, zeolite wheels offer advantages over other types

of desiccants.

Lithium Chloride

If your application requires high mois-

ture removal capacity with minimal

energy requirements over a broad range

of humidity levels, lithium chloride wheels

are especially useful. Also, as a natural

inhibitor of microbiological growth, lithium chloride

desiccant wheels are often used where minimizing bio-

logical contaminants is essential.

Titanium Silica Gel

When your installation requires opera-

tion in highly saturated air streams,

titanium silica gel is an excellent choice.

It has moderate moisture capacity over a

broad range of humidity levels with moder-

ate reactivation energy requirements. No silica gel

wheel outperforms the Titanium gel wheel. Resistant

to wash out, these enhanced wheels provide 90% or

greater efficiencies for up to ten years of operation.

DESICCANT OPTIONS

We manufacture five different types of desiccant

wheels, each with distinct absorption characteristics.

HCR Desiccant

Munters proprietary HCR wheel is an

adsorbent wheel that is designed to

use low temperature air for reactivation.

The wheel is standard in Munters HCU

dehumidifiers. HCU dehumidifiers use refrig-

eration waste heat for desiccant reactivation.

Off the Shelf Units (HC)

At the smaller end of our product line we make standarddehumidifiers with capacities from 30 to 300 scfm (stan-dard cubic feet per minute). You can install these easilyby plugging them into a wall socket and connecting duct

work. They come complete with fans and heaters.These units can operate automatically and are oftenused in applications like archival storage, museums, smallenvironmental chambers and military storage applications.For example, three of these units currently protect

Leonardo da Vincis famous fresco The Last Supperfrom excess humidity.

Modular Units with Options (HCD)

For customers who need to integrate desiccant dehumidi-fiers into their own processes or air conditioning systems,

we offer our HCD-series modular dehumidifiers withcapacities from 600 to 12,000 scfm. These modules canbe combined to form even larger systems.

Along with the basic HoneyCombe rotor-drive-and-seal assembly, we can provide your choice ofprocess and reactivation fan and either gas, steam orelectric reactivation heater modules for you to integrate

into your system. We can also supply modular heatingand cooling coils and filters in air- tight enclosures to workalong with the dehumidifier.

These modular dehumidifiers are used in a very widevariety of applications from clean room humidity controlto chocolate coated candy and central dry air systems forpharmaceutical manufacturing.

Integrated Custom Air Handler (ICA)

The ICA is a state-of-the-art double wall custom airhandling system. Its unique panel design provides a trueno through metal construction. Panels are available in2.5 and 4.0 thick construction to prevent external con-densation in even the toughest environments. The large,smooth-fitting panels of the ICA create fewer joints,preventing leaks and improving sanitation.

Often customers ask us to engineer and assemblean entire dehumidification and air conditioning system

including cooling and heating elements and sophisticatedcontrols, as well as the dehumidifier. All components areassembled on an aluminum skid and tested as a system atthe factory. The systems are available in airflow capacitiesfrom 400 to 100,000 scfm.

Our ICA systems are often used for hundreds ofcritical manufacturing processes such as surgical suturepackaging, production of computer microprocessors and

controlling humidity in plutonium-handling rooms.When you need the ultimate in reliability, consider one

of our custom-designed ICA systems to save you the timeand costs of designing and testing your own system.

The ICA concept can save thousands of dollars andreduce coordination problems on the job site because thesystem arrives ready-to-run after connection of duct workand utilities. Your in-house design time is reduced andon-site construction is simplified. Many of our customers

find these benefits are especially useful when their designresources are limited or where skilled labor is costly orhard to find. And for ICA systems, factory-trained serviceengineers are available for start-up and service contracts.

With a Cargocaire ICA, you can relax and concentrateon other aspects of your complex projects, knowing thedesign and construction of your dehumidification systemis in good hands.

Large-scale Modular Dehumidifiers (HCE)

To dry airstreams larger than 10,000 sfcm that do notrequire treatment other than dehumidification, our HCE-series of modular units are the ideal choice. Available infour sizes from 15,000 to 40,000 scfm, the HCE modulescan be combined to dry airflows of any size.

Our modular approach to large airflows is economicalcompared to a single-unit design because individual mod-ules can be brought on-line or shut down as the moistureload changes. This avoids the cost of running a single large

unit for a small moisture load. In some cases, the energycost savings of a modular approach to large systems can bemeasured in tens of thousands of dollars per year.

Special Purpose Dehumidifiers

Occasionally, customers need dehumidification solutionsthat are highly specific to a single purpose. For example,

we supply dehumidifiers with special materials and strin-gent vibration and noise specifications to dry out missiletubes in the Trident Nuclear Submarine. We also providespecial portable dehumidifiers with structural bases andlarge casters which are used for temporary drying ofbuildings and emergency replacements in industrial pro-cesses. We can respond to unique situations, giving you

just what you need at a price which meets your budget.
