Your plants – dry, clean, sustainable.

GIEBEL Adsorber® extend the running times of your plants, ensure the quality & longevity of the operating fluids, prevent condensation water damage and protect man & the environment from the escape of pollutants. The heart: The highly efficient desiccant mixture GIEBEL Xdry®, which allows application even at high temperatures and low humidities.

Sensors of the GIEBEL Sense® series, especially developed for adsorbers, take over the monitoring of the loading condition and inform in time about upcoming maintenance intervals. Other accessories solve design challenges when space is limited, prevent overpressure and underpressure, protect against oil leakage and more.

And because sustainability is a major concern for us, we have created our own recycling system, GIEBEL Refresh®, in which we recycle loaded adsorbers.

Designed and produced in Germany.

As specialists for aeration dryers and oil mist separators, we develop and produce individual solutions in addition to a broad standard product portfolio at our Bretzfeld site.

The main application areas of our GIEBEL Adsorber®.

Use them on …

Hydraulic power packs

By drying the incoming air, adsorbers protect hydraulic power packs from condensation damage.


Sucked in, moist ambient air significantly reduces the service life of a gear oil. Adsorbers can prevent the entry of humidity.

Barrels & IBC

Breathing dryers from GIEBEL can be used to protect hygroscopic substances in barrels and IBCs like isocyanate, oils and biological fuels.

Storage tanks

When tanks cool, moist air leads to condensate and thus reduces the quality of the substance contained. GIEBEL has developed special tank ventilation dryers to keep the air dry.


GIEBEL dehumidifiers protect transformers from hydrolysis of the cellulose paper in the transformer and thus from a reduction in its degree of polymerisation by effectively drying and filtering the sucked in moist supply air.

We also provide you with Accessories, Spare Part Kits & Desiccants.

Upgrade your adsorber


At GIEBEL we design numerous accessories that adapt the use of our ventilation dryers to your operational requirements.

Spare Parts Kits

Reuse the durable components of an adsorber over and over again – and replace just the inner workings. That is sustainable.


The core of our adsorbers: desiccants. For more about silicagel, molecular sieve and other desiccants visit our desiccant website.



Adsorbers adapted to your corporate design with your own label sticker and in matching color.

GIEBEL Refresh®

Sustainability is important to us. That is why we take back used adsorbers and recondition them.
