Application
Due to a flexible modular system and trouble-free customization, our adsorber is in use for multiple applications on each of all five continents.
The most applications that are aerated and deareated:
- hydraulic aggregates
- gears
- rolling bearings
- draw works for crude oil production
- hydraulics for deep drilling systems
- transformers
- oil – cycling – systems
- fuel storage tanks
Waterless aeration of hydraulic oil storage tanks
Only with precise knowledge about the operational characteristic of the hydraulic aggregate a suitable adsorber can be customized.
Waterless aeration of gears

Wasserfreie Belüftung von Kraftstoffen

Jeder Lagertank hat ein sich ständig bewegendes Luftpolster, entweder durch Tankentnahme oder durch Temperaturunterschiede (Tag / Nacht).
Der Giebel Adsorber der Baureihe DUO-VARIO BD 5 bindet die Feuchtigkeit der Umgebungsluft. Feuchte Umgebungsluft führt bei Abkühlung zu „Tau im Tank“ und somit zu einer Qualitätsminderung des Kraftstoffes.
Bei biologischen Kraftstoffen kommt die Bildung von Bakterien, Algen und Schimmelpilzen erschwerend hinzu.
Die Giebel Adsorber erhöhen stattdessen die Standzeit immens.
Waterless aeration of aggregates used in crude oil production - draw works
Adsorbers of the line DUO – VARIO 3 come in use various models (also ATEX) for hydraulic aggregates, applied in brakes and lubricating systems for hydraulic transmission.
The worldwide operations of draw works (ashore and offshore) require high quality standard from the adsorber.

Especially for aerating hydraulics oil of an aggregate, installed inside a container, e.g. for drilling systems, our adsorber DUO – VARIO AV 7-MAB-FL with mounted flange, in case of hydraulics made for horizontal drilling machines the adsorber DUO – VARIO AV 3-MA, comes in use.
The customization of the adsorber depends accordingly to the type of oil (mineral oil, synthetic oil, biodegradable oil), an on the temperature of the oil and ambient air.
