Pressure-induced dieseling and element spark discharge generate sub-micron insoluble carbon-based particles that cannot be removed by traditional particulate filtration. The ECR combines a high-voltage electrostatic field with a proprietary collector element design to remove the sub-micron particles that are the cause of dark EHC fluid and high varnish potential values (MPC). Used in conjunction with patented ICB ion-exchange filters engineered to remove acids and soluble varnish at the molecular level, dissolved contamination is addressed, removing phosphate ester varnish. Additional contaminants that come out of solution are removed when the fluid passes through the high-efficiency particulate filter. Together these three leading filtration technologies maintain the quality, life and reliability of EHC fluids.

With typical analysis showing as little as 10% of the contamination present, specialized testing through the EPT Clean Oil Fluid Technical Center documents results to ASTM D8323-21 standards.
