APPLICATIONS:
Eni Arnica 22 is a high performance antiwear hydraulic oil, specifically designed to meet the
needs of modern, high pressure, industrial and mobile equipment hydraulic systems.
It’s formulated with selected base oils treated with “low zinc” technology ensuring excellent
thermal, oxidative and hydrolytic stability.
Eni Arnica 22 is recommended for outdoor equipment which are likely to operate in wide
temperature range, such as systems where cold start-up and high operating temperatures are
typicals (marine applications). It’s suitable also for indoor manufacturing equipment that
incorporates control systems requiring minimal viscosity change with temperature.
CUSTOMER ADVANTAGES:
• Suitable for applications operating in a wide temperature range thanks to high a viscosity
index and an excellent viscosity stability
• Suitable for hydraulic systems with very thin filters (3 microns)
• Prolongs oil charge life extending re-lubrication intervals thanks to very high termoossidative stability
• Protects hydraulic pumps and components thanks to oustanding antiwear property
• Helps prevent aeration and cavitation damage in low residence time systems thanks to
rapid air release
• Compatible with a wide variety of component metallurgy
• Maximizes water removal system efficiency thanks to excellent demulsibility
