Ventilation Dryer for Hydraulic Units 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.

Use of the series VARIO Special feature: Stable aluminum valve part, large frost-proof aluminum valves, pre-filter disc for dust, oil master for outflowing air Areas of application: Longer maintenance intervals, larger tank volumes, dusty ambient conditions, high air throughputs, high oil mist emissions Advantages: Disadvantages: Excellent air drying, no sticking or freezing of the valves, separation of oil aerosols, easy handling without tools, long maintenance intervals due to high quantity of drying agent Higher construction by valve part Use of the series VENT Special feature: Smaller dimensions, easy assembly, larger choice of sizes Areas of application: Restricted installation conditions, smaller tank volumes, lower air flow rates Advantages: Disadvantages: Reasonable purchase costs, low installation dimensions Valves not suitable for very dusty or very cold environments, no adequate oil separation during oil mist emission GIEBEL FilTec GmbH Web www.giebel-adsorber.de Email info@giebel-adsorber.de Tel +49 (0) 7946 944401-0 13.12.2016 2/5
