How water separators work

Explore how water separators work, why they are indispensable for protecting gearboxes that are used outdoors or cleaned with water, and how they save you nerve-wracking, time-consuming, and costly maintenance work.

Protection

The robust PA6 housing and ePTFE membrane block liquid water while allowing clean air to enter.


Airflow

Air passes through the ​​​GIEBEL HS-D​​​ opening for pressure equalization as the system breathes.


Separation

Water droplets are repelled by the hydrophobic membrane and drained away safely.

Equalization

Balanced airflow through the thread connection keeps internal pressure stable and the system protected.

FAQ regarding adsorbers in general.

Malfunctions & troubleshooting

What is adsorption and why is it essential?

Adsorption is a physical process in which atoms or molecules, known as the adsorptive, attach to the surface of a material called the adsorbent. This can take place in both gas phase and liquid phase systems, depending on whether the surrounding fluid is a gas or a liquid.

Adsorption is critical for maintaining the performance and reliability of hydraulic systems, gearboxes, barrels & IBCs, storage tanks, and transformers. It helps reduce downtime, extend equipment life, and improve operational efficiency.

How do GIEBEL Adsorbers® protect systems from moisture and contamination?

GIEBEL Adsorbers® are engineered to prevent condensation inside hydraulic systems, gearboxes, storage tanks, barrels & IBCs, and transformers. As systems breathe during operation or temperature changes, moisture can enter and condense internally, causing corrosion, oil degradation, and system failures.

Each adsorber is filled with GIEBEL Xdry®, our high-performance desiccant mixture that adsorbs moisture before it can enter the system. This stops condensation at the source. With integrated particle filters, GIEBEL Adsorbers® also block contaminants, ensuring clean and dry system conditions and extending the service life of your equipment.

What types of systems benefit from using GIEBEL Adsorbers®?

GIEBEL Adsorbers® are used in a wide range of systems where preventing condensation and contamination is critical. These primarily include hydraulic units, gearboxes, storage tanks, barrels & IBCs, transformers.

Any system that exchanges air with its environment is at risk of moisture entering and condensing inside. GIEBEL Adsorbers® prevent this by adsorbing moisture and filtering particles before they can enter the system, making them essential for maintaining reliability and extending the service life of equipment across many industries.

What are GIEBEL Adsorbers® made of?

GIEBEL Adsorbers® are made from high-quality materials designed to withstand harsh environments and provide long-lasting protection. Each unit includes a durable housing, which can be made from aluminum, stainless steel, or plastic depending on the application. Inside, the adsorber is filled with GIEBEL Xdry®, our desiccant mixture that effectively adsorbs moisture from the air.

To ensure complete system protection, every adsorber also includes integrated particle filters that block dust and contaminants. Depending on the model, optional accessories can be attached to meet specific system requirements. Every component is selected to deliver reliable performance and keep systems clean and dry.

How do I maintain my GIEBEL Adsorber?

GIEBEL offers both rechargeable and disposable adsorbers, each with a different approach to maintenance.

Rechargeable adsorbers can be serviced when the desiccant becomes saturated, as indicated by the color change of GIEBEL Xdry® from orange to green. These units are designed to be opened and refilled with fresh desiccant, and many models are supported with spare part kits containing replacement seals, filters, and other components to ensure full restoration of performance.

Disposable adsorbers are replaced entirely once the desiccant is saturated. GIEBEL Xdry ® does not contain cobalt dichloride or other toxic substances, making our disposable units safe to handle and environmentally friendly during disposal.

Regularly monitoring the desiccant color and replacing or servicing the adsorber as needed ensures continuous protection from condensation and contamination across all applications.
