APPLICATIONS:
Eni Arnica S 46 is a high performance hydraulic oil, specifically designed for hydraulic systems
exposed to fire hazard owing to the presence of very high temperatures, such as in rolling mills
or other ignition sources are present such as electric arc and welders.
It’s based on organic biodegradable esters with very high viscosity index and high flash point. It
has outstanding antiwear, anticorrosive and antirust properties.
Thanks to its biodegradability characteristics, Eni Arnica S 46 is recommended for hydraulic
systems of industrial vehicles operating in environmentally sensitive areas.
CUSTOMER ADVANTAGES:
• Fire resistant
• Biodegradable over 70% according to the OECD 301B method
• Suitable for applications operating in a wide temperature range
• Maximizes water removal system efficiency thanks to excellent demulsibility
• Protects components thanks to outstanding antiwear properties (FZG Failure Load
Stage:12°)
