The smallest amounts of free water can cause acidification in oils and corrose component surfaces. An increase in water content can dramatically alter the characteristics of the oil. The consequences include reduced load capacity, lower temperature resistance and, ultimately, rapid oil oxidation (aging), which all result in economic damage.
Free water can be detected by the milky clouding of the oil irrespective of the oil’s color.
Some of the causes of water in hydraulic and lubricating oil:
ambient moisture splash water cooler breakage
With the new COPS mobile dewatering unit large quantities of free water can be removed economically.
The oil is heated and channeled into a vacuum chamber. The water is removed quickly, long before the saturation limit is reached, thanks to the reduced steam pressure.
A fine filter is installed downstream from the drying process to ensure that the oil is dry and filtered when it flows back into the machine or tank.
Water content is constantly monitored with the ARGO-HYTOS “LubCos H2O+” oil condition sensor. A digital display reading relative humidity and indicator lights showing the current state of the dewatering process.
Thanks to its compact design, low weight, high efficiency, and ease of use, COPS can operate in places where space is limited.
