Product Profile of Industrial Oil Purification Systems

AR Engineering manufactures Industrial Oil Purification Systems. AR Engineering offers various types of oil filtration plants and varnishing machines. The Industrial Oil Purification Systems are widely used in diverse industries. The systems consist of filtration / purification stages for economical operation. In pre filtration stage coarse particles are removed using cleanable / washable elements. In intermediate stage the major portion of the contaminants removed by using the properly selected filter elements suitable for oil to be purified. In final stage the fine contaminants are removed by special elements to suit the final application and purification level. The free moisture removal in the Industrial Oil Purification System is carried out either by gravity separation methods such as spirafuge, centrifuge or by using coalescer elements. Dissolved moisture is removed partially by coalescer elements and finally by vacuum treatment.

Following modules are used frequently in Industrial Oil Purification Systems:

• Pre Filters:
-Strainers: with suitable size perforated or wire mesh element are used to remove major portion of suspended particles.
-Magnetic Filters / Separators: These are used to remove magnetic impurities. These are used especially to filter the cutting oil / coolant where the magnetic dirt contaminates oil during processes such as grinding, honing, reaming etc.
-Spirafuge: These are used to remove free moisture and coarse suspended particles from oils. In these the oil is given the spiral path around the filter strainer so that vortex is formed at the bottom so that heavier particles and water are collected at the bottom and can be removed periodically by opening drain valve. The dirt is collected on the surface of the central filter element which is carried by the oil to bottom when drain valve is opened so the filter is cleaned without opening the filter chamber.

• Fine Filters:
-Coalescer filter / separator: These filters remove free as well as emulsified water from the oil. Depending on the type of oil water can be removed to less than 50 - 100 ppm.
-Fine filter elements: These remove the particles down to desired level as per the application.
-Centrifugal Filter: In centrifugal Filter oil passes through a rotor spinning at high speed so that particles in the oil are deposited on the inner wall of rotor to form a dense cake. It is particularly more suitable for permanent fitting on the oil tank. It has more dirt holding capacity as compared to normal depth filter of fine micron rating. Centrifugal separation is most suitable way to remove small hard metallic particles.
