What can EOC do?
EOC is able to remove all of the oil-insoluble particles, whether they are made of metal, non-metal, organic, or inorganic materials.In particular, it removes oil oxidation products, primary culprits for causing malfunction of hydraulic systems. Also it is the only device capable of removing oil oxidation products that are difficult for filters to remove.
The EOC makes use of principles that the contaminants floating in oil are electrically charged and trapped by electrodes. The particulates floating in oil may be electrically classified into three types, i.e., those charged positively or negatively, or neutral one. The positively or negatively charged ones are attracted to the electrodes of opposite charges [electrophoretic migration] and neutral ones are attracted to the strong electric field generated by pleated type collector [dielectrophoretic migration].
EOC is an oil cleaner, adopting these two mechanisms simultaneously. Thus users of this type machine can get great benefits including
Basic installation method of EOC
・Adding a bypass oil circuit to the existing hydraulic oil tank
・No extra loads imposed on the existing oil circuits.
・Please consult us for detailed installation
①Removal of oil oxidation products, thereby enabling to maintain oil clean.
②Improvement of productivity by reducing hydraulic problems, preventing intermittent interruptions, stabilizing cycle times, and cutting warm-up operation times.
③Realization of keeping clean environment through prolonging lifetime of oil.
④Realizing power savings, resulting in significant cost cut for users.
