Storage tanks are gradually emptied during their use. To equalize the pressure, air flows in from outside. If hygroscopic substances are stored in the tanks (such as isocyanate and bio-oils), the humidity flowing in with the outside air causes a reduction in the quality of the stored substance. This process is accelerated by temperature fluctuations, especially when temperatures fall below the dew point and condensate forms. This also causes corrosion damage inside the tank.
Our GIEBEL breather dryers provide a remedy by drying the incoming air in advance. The desiccant contained in the dehumidifier absorbs the moisture and indicates by a color change when the adsorber is fully loaded and should be replaced.
