Gear units heat up during operation. This increases the oil volume and air is forced out of the gear unit to compensate for the pressure. When the gear unit cools down again at standstill, the oil volume decreases and air flows in from outside the system. The moisture contained in the air is thus introduced into the system and condenses as soon as the dew point is reached. Hydrolysis (rapid aging and degradation of additives), corrosion and poorer lubrication are resulting effects. Our GIEBEL ventilation dryers provide a remedy by drying incoming air in advance. The desiccant contained in the dehumidifier absorbs the moisture and indicates by a color change when the cartridge is fully loaded and should be replaced.
GIEBEL oil mist separators are used where the escape of oil aerosols from the plant is to be prevented. They make an important contribution to improving air quality and protecting employees.
Our GIEBEL Water separators protect gearboxes from water droplet ingress while allowing them to breathe. They are an excellent alternative to adsorbers when liquid water is a challenge for a gearbox, but humidity does not cause problems.
