1) CBS products are useful for railway, NTPC, and NHPC applications including locomotive sheds, substations, power stations, and hydroelectric plants. 2) Turbine and transformer oils are used for lubrication and insulation purposes. Proper filtration removes contaminants like water, solids, and gases to maximize oil life. 3) Centrifugal filtration systems from 1,000-5,000 LPH are used to purify turbine and other oils for various applications like locomotives, bowlmills, and switchyards. Maintaining clean oil through removal of contaminants like water extends equipment life.
