HOME > Product > Electrostatic Oil Cleaner EOC > Realization of power savings/Prolonged oil life
We would like to report successful management of hydraulic oil using electrostatic oil cleaner, enabling to save electric consumption of machines.
When an electrostatic oil cleaner is used to clean oil, power consumption is significantly reduced resulting in cost cuts - even taking into account the electric cost for running the electrostatic oil cleaner.
Measurement method | Attaching a power meter and a printer to the 850 ton molding machine of Company T, we measured its average power usage every 30 minutes one week before oil cleaning was performed. We did the same 9 days after oil cleaning was performed. | ||||||||||

Table below shows the changes in oil conditions for 7 years when the electrostatic oil cleaner is used. As apparent in this table, the cleanliness, the NAS class, and water concentrations are all controlled to normal conditions, requiring no need of oil replacement for 7 years in order to make malfunction-free operation of machines.
