In order to completely solve water problem of fuel, lube oil, turbine oil, hydraulic fluid etc, ACORE developed Coalescer Oil and Fuel Filtration System with advanced “coalescing and separation” dehydration technology. It combines the functions of precision filtration and high-efficiency dehydration to efficiently remove particulate contamination, emulsified water, dissolved water and free water in the oil, and achieves NAS4-6 grade filtration accuracy, achieving continuous operation and unattended operation.
There are two sets of different function filter elements inside the Coalescer Oil Separator – coalescing filter element and separation filter element. When the oil flows through the coalescence separator, it undergoes four stages of filtration, coalescence, sedimentation, and separation in the interior, and the function of filtering out particulate dirt and removing water is realized.
The oil flows from the inside to the outside first through the coalescing filter element. The coalescing filter element is suitably combined with special glass fiber and other synthetic materials and is specially formulated for turbine oil with good hydrophilicity. The coalescing filter has the dual function of filtering particulate contaminants and agglomerating moisture. The innermost high-precision filter material first removes particulate contaminants from the oil; the outer demulsification coalescing layer coalesces the tiny droplets of the oil into water droplets. Larger droplets of water will rely on their own gravity to sink into the collection tank. Smaller droplets of sediment will not be settled and will flow to the separation filter element. The separation filter element is made of a specially treated stainless steel mesh and has a good hydrophobicity. When the oil flows from the outside to the inside through the separation filter element, the small water droplet is effectively intercepted outside the filter element, allowing only the oil to pass through. The water passes through to further separate the water.
The oil is first filtered out of the oil in the initial filter and then into the Coalescer Oil Filtration System. In the coalescence separator, the oil passes through four processes of filtration, coalescence, sedimentation, and separation to achieve the function of removing water, and finally output purified oil. The water settled in the sump is removed by a drain valve on the sump. At the same time, according to the oil conditions, the oil can be directly filtered through the filter to remove the particulate contaminants in the oil, and the purified oil can be output.
