Case Studies


Silica gel for transformers

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.

Adsorber on a 3D printer

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.

Adsorber for Closed Cavity Facade

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.

Adsorber on an excavator

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.

Adsorber on a baling press

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.

Adsorber on a refuse collection vehicle

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

Adsorber on sulfuric acid tanks

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.

Diesel tanks of emergency power systems

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.

Transmission in the Weir

Transmission data:

  • 4x Gearbox with an age of about 20 years
  • Oil volume in the gearbox
  • Cycle every 2 hours
  • Influence of sun and weather indirectly present
  • Long downtimes, less frequent operation

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.

Oil mist separator on a hydraulic power unit

Hydraulic data:

  • Operation: continuous use
  • Hydraulic tank with 50-70 l oil volume
  • Hydraulic oil HLP46 mineral oil
  • Oil exchange volume: 35l / min in the circulation
  • Oil temperature 50-60 degrees

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.

Hydraulic unit at an Injection molding machine


  • Building year: 2002
  • Closing force: 31.500 kN
  • Oil type: Mobil DTE 25
  • Tank volume: 6.000 Liter
  • Cycle time: 98 to 120 sec.
  • Number of cycles: 720 to 881 per day

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.

Hydraulic unit in a wheel rolling mill

Objectives: Prevention of condensation and permanently good oil quality

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.
