Protect hydraulics against corrosion, loss of oil quality, poor lubrication & the escape of pollutants.
Have you noticed condensation droplets inside your hydraulic tank or even worse: Rust, free water and dirt in hydraulic oil, poor lubrication, signs of abrasion and an oily smell when the unit is running? The cause: moisture and dirt particles entering your system unhindered every time it draws in air to equalize pressure, plus oil aerosols escaping when it breaths out.
Let‘s face it, if you don‘t do anything about it, you‘re heading for expensive maintenance work and damage to employees and environment.
Luckily, there‘s a solution: the installation of an GIEBEL Adsorber®. It dries and cleans the supply air and prevents pollutants from escaping - saving you maintenance work and money.
Why water & dirt should be you biggest concern?
When metals react with oxygen and water, this is known as corrosion. It leads to the formation of hard, highly abrasive particles. In hydraulic oil contaminated with water, these metallic impurities trigger an oxidative chain reaction. Free radicals are formed, which attack the hydrocarbon molecules and break down the oil. But that‘s not all: when oil additives react with water, acids are formed that further accelerate the decomposition. Over time, oil properties such as lubricity, viscosity and shear strength change.
With higher flow characteristics, friction points are no longer supplied with the necessary volume of hydraulic oil. Extremely viscous oils, on the other hand, put a strain on the system‘s drive units and reduce efficiency. Oil ageing residues clog valves, sludge formation increases filter requirements and acidification hightens the risk of corrosion of all metallic components, plus impairs the seals.
Preventing the entry of moisture and dirt as well as the formation of corrosion is the top priority in order to operate hydraulic systems for a long time, cost-effectively and with low maintenance! Exactly what our GIEBEL Adsorbers® do!
Hydraulic without adsorber.
1. The hydraulic unit equipped with a standard filter cap is exposed to humid ambient air.
2. The oil level drops and air flows in to equalize pressure. The filter cap allows moisture to enter. If the temperature falls below the dew point, condensation forms.
3. The oil level rises, air is pressed out to equalize pressure. The filter cap allows oil aerosols to escape.
Hydraulic with adsorber.
1. The hydraulic unit equipped with an adsorber is exposed to humid ambient air.
2. The oil level drops and air flows in to equalize pressure. The adsorber separates moisture down to 2% RH (10% RH on average) and filters out dust particles. The system remains dry.
3. The oil level rises, air is pressed out to equalize pressure. The adsorber prevents oil particles from escaping. In addition, the air flow removes some of the previously stored water from the adsorber, thus ensuring cyclical self regulation.
Breather dryers
Breather dryers adsorb humidity and thus prevent water from entering hydraulic tanks. They protect against corrosion, loss of oil quality and poor lubrication.
Oil mist separators
Oil mist separators prevent oil aerosols and other pollutants from escaping hydraulics. They protect employees and the environment from contact with harmful substances.
