Eni Arnica S 46
Biodegradable ester hydraulic oil for areas at risk of fire
ISO VG 46
Eni Arnica S/FR 46 is a biodegradable hydraulic oil approved by Factory Mutual. It is intended for hydraulic systems at risk of fire from very high temperatures, as in rolling mills, or from ignition sources such as electric arcs and welding. It is based on biodegradable organic esters with very high viscosity indices and high flash points. It has superior resistance to combustion and excellent self-extinguishing properties (oil mist flammability test). Eni Arnica S/FR 46 is also recommended for the hydraulic systems of construction and agricultural vehicles operating in environmentally sensitive areas.
