Aerospace Facilities Group, Inc. uses a unique horizontal bed design with over 30 years of proven technology to provide our customers with the smaller designed dehumidifier.

Our Humidity Control System® (H.C.S.®) series ranges from 25 to 300 CFM (cubic feet/minute). We offer three standard sizes that both meet and exceed the industry standards: H.C.S.® 50, 150, and 300. The units are delivered complete and ready to run with only electrical and ductwork connections needed for installation. Our H.C.S.® Series dehumidifier is the perfect addition to your environmental corrosion control for aircraft, AGE, buildings, and munitions storage.

All of Aerospace Facilities Group, Inc. H.C.S.® equipment is portable. H.C.S.® can be used to control the corrosion on AGE, aircraft (such as F-15, F-16, F-22, F-35, C-17, KC-135, U-2), storage buildings, and armament/munitions storage.

Aerospace Facilities Group, Inc. H.C.S.® units come with a limited 3-year labor and material warranty. A 10-year pro-rated warranty is offered on Tension Fabric Structures.

How H.C.S.® Works

Our H.C.S® equipment removes moisture from the air by means of a desiccant: a substance that absorbs water (in a vapor state). This desiccant is impregnated into paper sheets that are wound into a wheel (called the rotor).

The rotor is divided into two sectioned air streams: the process section and the reactivation section. When the processed air is passed through the rotor, the moisture in the air stream is absorbed by the rotor, leaving the dried air to be sent to the designated space. The water from the processed air will now be removed from the rotor in order to continue the indefinite process. The reactivation air provides this task. The air stream is heated between 270°-310° F. This heat passes over the rotor and sets free the bound water. This airstream is extremely humid and is ducted outside.

Corrosion Prevention

All materials corrode because every substance eventually changes from one form to another through chemical reactions. Many of these reactions, especially those which depend on oxygen, are catalyzed and accelerated by moisture. H.C.S.® works to protect materials from more subtle and expensive forms of corrosion.

No development costs: Humidity Control Systems® is commercial off the shelf (COTS) technology.

H.C.S.® Series Mobility and Durability at Its Best

With portability being an important issue to the military, Aerospace Facilities Group, Inc. has designed a line of dehumidifiers that can go anywhere and stands up to the toughest challenges planet Earth has to offer.

Aerospace Facilities Group, Inc.


We construct our Portable Series so that it will last through the most extreme conditions time after time. Hot or cold, dry or wet, you need a dehumidifier that will do the job right the first time, every time. Rely on an Aerospace Facilities Group, Inc. H.C.S.® desiccant dehumidifier to complete this task for you.


Both process and reactivation fans are centrifugal, direct drive, and include totally enclosed fan cooled motors. We also use higher static fans than the competition to provide the customer with the most powerful dehumidifiers in the industry.


Let us know what your personal drying needs are, and we can custom build an H.C.S.® Series dehumidifier that is tailored just for you. From trailers to motorized vehicles, we can customize a unit to fit any need or configuration.
