Hydraulic power packs

Giebel Hydraulik

When using hydraulic units, humid air is sucked in by pressure equalization with the environment, which condensate when the temperature drops below the dew point. The use in high humidity and temperature fluctuations can lead to condensation damage. Rapid aging of the hydraulic oil, the degradation of additives and the promotion of corrosion are only a few possible damages. To prevent damage caused by condensation, the use of a ventilation dryer is a very good measure. The incoming supply air is dried and thus a strong reduction in the water content and the dew point is achieved.

While a well designed ventilation dryer protects the hydraulic unit very efficiently, handling is very easy. The color change of the silica gel from orange to green indicates the status of the adsorber. GIEBEL FilTec has developed the VARIO and VENT series for protection of hydraulic power packs.

VENT PA D Efficient use Hydraulic power packs
VV 532x926VENT PA-D
The GIEBEL adsorbers of the VENT PA-D series are cost-effective solutions with and without valves. From small versions with 0,15kg desiccant up to 3,0kg different hydraulic tanks can be ventilated.
Adsorber Details VV PA D
VENT PA R Plastic valve Hydraulic power packs
vv PA R 556x962
The refillable desiccant filters VENT PA-R can also be equipped with or without plastic valves. By the possibility to exchange the desiccant and wear parts, these adsorbers have low operating costs.

FLANGE ADAPTER Stainless steel screws Hydraulic power packs
Suitable flange adapters are available for mounting a GIEBEL adsorber on a hydraulic tank. In the versions 3x M5 with bolt circle 41.3 mm or 6x M5 with bolt circle 73 mm according to DIN 42557 and as DN25 flange version, GIEBEL adsorbers can be easily mounted on all existing hydraulic systems.

 FILLING ADAPTER Filler Pipe Hydraulic power packs
The use of a filling adapter makes it easy to refill oil into a hydraulic unit. The 40 mm-sized filler neck makes it very easy to fill in the oil without having to remove the adsorber.

 PROTECTION ADAPTER Negative pressure Hydraulic power packs
By using a protective adapter to monitor a GIEBEL adsorber, an optical or electronic signal is transmitted if the negative pressure is too high. This makes it possible to see whether a filter needs to be replaced.

 OIL BYPASS ADAPTER Bypass filter system Hydraulic power packs
The bypass adapter allows the use of a bypass filter system without conversion measures on an existing hydraulic tank. At the same time, the use of a GIEBEL adsorber ensures ventilation and prevents further contamination of the hydraulic oil.

OIL MIST SEPERATOR Hydraulic power packs
Ölabscheider 2
By using an oil mist separator, a GIEBEL adsorber is protected from contamination by larger oil particles. Used on systems with a high oil mist outlet, the proportion of evaporating oil particles is reduced with the oil separator and the air is cooled down.

WALL MOUNT Concrete walls Hydraulic power packs
The wall bracket is suitable for the flexible installation of GIEBEL adsorbers with limited space available on the system. As a screw-on version for concrete walls, with clamping claws for steel girders or as a suspension version for grids or fences, no conversion measures are necessary on the system to use an adsorber.

 MOUNTING TUBE Commitment Hydraulic power packs
Montagerohr D
The mounting pipes facilitate the use of a GIEBEL adsorber if the adsorber can not be mounted due to its diameter.

Winkeladapter 1.3 3
Winkeladapter ANGLE ADAPTER
The use of an elbow adapter makes it possible to mount a GIEBEL adsorber on a horizontal barrel and, when space is limited, on hydraulic power packs and gears. This is achieved, for example, by a horizontal or offset installation. The GIEBEL Adsorber can thus be aligned in the desired direction and fixed with the counter nut.
