The electrostatic oil purification machine EDC captures contaminants suspended in oil by utilizing their charge and using electrodes. When classifying particles dispersed or suspended in oil by their electrical properties, there are three types: positively charged, negatively charged, and neutral. The positively and negatively charged particles are attracted to opposite electrodes (electrophoresis), and when a pleated collector is placed between the electrodes, a strong electric field is created that attracts neutral particles (dielectrophoresis). The EDC is designed to enable both phenomena to occur simultaneously. It removes all types of waste that do not dissolve in oil, regardless of whether they are metal, non-ferrous metal, organic, or inorganic. It can eliminate oxidized and altered substances in oil that are difficult to remove with filters. 【Features】 - Increased productivity - Maintenance of a clean environment - Prevention of machine failure and downtime - Prevention of product defects due to machine malfunction - No generation of waste oil, which is a source of environmental pollution For more details, please contact us or download the catalog.
