Diesel fuel operator (can use water-glycol based hydraulic oil)
Our company's electric oil controllers "HOP," "EOP," and "COP" series.
Even in environments where mineral-based oils could not be used, electric oil controllers are effective.
The Okaya Seiritsu electric oil controller can also be used with water-glycol-based hydraulic fluids. ◆ Flame Retardant Due to its superior flame retardancy compared to mineral oils, it can be used in a wide range of environments (fire prevention, compliance with fire safety regulations, etc.) ◆ Stability It is resistant to heat and oxidation, making it less prone to degradation, and has minimal viscosity changes in response to temperature fluctuations, allowing for stable control. ◆ Oxidation Prevention Since it contains vapor-phase rust inhibitors, it exhibits rust prevention even on surfaces that do not come into contact with the hydraulic fluid.
