Mobile and stationary generators are used wherever a public power grid is missing or the failure of the power grid would have serious consequences. These reliable systems supply e.g. Hospitals, chemical plants, server rooms and nuclear power plants, in order to ensure the dissipation of decay heat even in the case of shutdown or failure of the power grid.
In many areas, sulfuric acid is used, e. g. for the production of surfactants, dyes. For processing, the acid must be stored under optimal conditions and protected from entry of water. Storage tanks with mounted ventilation dryers take over this task.
GIEBEL Adsorber® increases the quality of PUR foam products and reduces production waste. The effective drying of the air protects isocyanates, polyols and other chemicals from contamination by water during storage and processing.
The freeze-drying process is mainly used in the processing of food and the production of pharmaceutical products. The temperature fluctuations of a freeze-drying plant pose a great challenge to the oil or nitrogen used as a refrigerant. However, there is a better alternative: the use of a respiratory dryer, which reliably prevents damage caused by condensation.
In recent years, numerous environmentally friendly alternatives to conventional hydraulic oils have been developed. They are mainly used where a leak in the tank could lead to a pollution of the environment. The bio-based hydraulic oils are becoming more and more popular and the use of an adsorber can help to save costs.
Silica gel is used in many areas for dehumidification and can absorb up to 40% of its own weight in water. Ventilation dryers with silica gel are used on power supply transformers to largely eliminate moisture as a cause of faults and progressive ageing. The silica gel binds the penetrating moisture in its pores and thus protects the transformers.
3D printers have long since arrived in industrial production, where they are used to print on metals, plastics or other materials. For excellent printing results, the processed raw materials must be dry and free of foreign matter. An adsorber attached to the material container dries the air as soon as it is fed in, so that the raw materials cannot absorb water from the air.
Modern office buildings are designed to be energy-efficient and environmentally friendly, among other things by means of a closed cavity facade (CCF). Respiratory dryers are used to counteract the effects of seasonal temperature fluctuations. They effectively prevent the formation of condensation water in the closed facade space.
One of the most important components on excavators and other mobile machines is the hydraulic system. It ensures that the tasks set can be performed in all weathers. In order to ensure that they function trouble-free over a long period of time, the hydraulic tank must be protected against condensation. An adsorber mounted on the excavator with a special valve adapter takes over this task.
In waste management companies, a baling press is used to compress the numerous recyclable and residual materials. In order to ensure smooth processing of the various materials, the balers used must also function smoothly under special environmental conditions. The breathing dryers attached to the hydraulic tank of the system ensure this.
In all German cities, refuse collection vehicles of the local waste disposal companies are in daily use to collect recyclable and residual materials. A high degree of reliability is expected of the vehicles despite constant operation. In order to keep the maintenance intervals as long as possible, the hydraulic tanks of the refuse collection vehicles are equipped with adsorbers
GIEBEL Adsorber® is used in the manufacture of plastic products. When processing different substances adsorber and a special desiccant reduce the reworking effort to a minimum and extend the maintenance interval.
GIEBEL Adsorber® protect hydraulic tanks of mobile docks even under harsh environmental conditions. Mobile dockside hydraulic systems must withstand exceptional conditions due to their proximity to the water to ensure reliable operation.protect the hydraulic tanks anywhere in the world.
GIEBEL Adsorber® protect hydraulic tanks anywhere in the world. A very extreme condition is the use on the deck of a cruise ship. High humidity, high temperature fluctuations as well as rain and waves must not have any influence on the hydraulic oil.
GIEBEL Adsorbers® protect the hydraulic tanks of snow groomers and thus guarantee reliable operation and long maintenance intervals, even under extreme temperature influences. Why are ventilation dryers especially useful for these machines? And what is the added value?

Transmission data:
Weir systems provide sufficient water depth in rivers and canals to allow shipping. Furthermore, weirs allow a slower flow rate of the water, which makes riverbeds and bridge piers less flushed or undermined.
Hydraulic data:
Hydraulic power units are used in oil circulation lubrication systems. These systems cool and lubricate bearings and gearboxes. Particularly in the case of large or high-speed transmissions in which a high temperature load is present due to the rotational speed or ambient temperature, oil circulation lubrication offers advantages. The oil in the circuit is removed from the hydraulic tank and returned again.
Data to the plant:
Sugar beets based on sugar beet and sugar cane are produced using GIEBEL adsorbers. Carefully designed ventilation dryers are dimensioned to save space.
Specifications:
To prevent condensation damage in May 2014 GIEBEL adsorber of type DUO-VARIO 560-PA were assembled at several plastic injection molding machines with servo hydraulics. Not only the high acquisition and maintenance costs of the plant, but also the high number of cycles and thus the load of the hydraulic oil with moist air have moved to implement this measure.
The results speak for themselves and demonstrate the added value of a ventilation dryer to hydraulic units. The water content in the oil has fallen steadily after the assembly of the adsorber.
Water and dirt particles are 80% the cause of damages in hydraulic systems, gears and bearings. In many industrial companies extremely environments are everyday followers and sources of high costs.
In July 2013, a GIEBEL Adsorber® was mounted on a hydraulic unit in a German wheel rolling mill, together with a 600l fresh oil filling.
During a 4-month observation period, the oil was checked monthly for contamination and, in particular water content in a laboratory. During this time the hydraulic unit was used unchanged and operated continuously. It was exposed to the usual influence conditions in a rolling mill without restrictions.
The result speaks for itself: No water in the oil! The amount of water absorbed was unchanged over the entire period and the oil quality was on fresh oil level! However, the previous year's figures, without GIEBEL Adsorber®, point out a significant difference.
