Manufacturer's description

Environmentally acceptable, synthetic hydraulic fluid. Shell Naturelle S2 Hydraulic Fluid 32 is an advanced hydraulic fluid for use in hydraulic and power transmission systems. Readily biodegradable with low ecotoxicity, it is particularly suited for use in environmentally sensitive areas. Fully synthetic esters, blended with ashless additives, give it an excellent blend of lubrication performance and environmental acceptability. ISO VG 32 grade with a kinematic viscosity of 32.5 cSt at 40 °C and a viscosity index of 196. Bulk operating temperature should not exceed 90 °C.

Applications

• Environmentally sensitive areasShell Naturelle S2 Hydraulic Fluid is an ‘environmentally acceptable’ hydraulic fluid (ISO 15380 HEES), with ‘reduced harm for water and soil during use’ (EU Ecolabel). When compared to conventional mineral oil hydraulic fluids, it will have a reduced environmental impact in the event of a leak or accidental spillage. It is particularly suited for use in environmentally sensitive areas. However, Bulk operating temperatures should not be allowed to exceed 90 0 C.

Performance & benefits

• Excellent wear protectionAdvanced ashless (zinc and metal free) anti-wear additives provide protection over a wide range of conditions – proven protection in tough industry standard tests such as the Eaton Vickers 35VQ25 vane pump and Komatsu HPV35+35 high pressure piston pump.
• Maintaining system efficiencyExcellent viscosity/temperature characteristics can minimize the changes of viscosity with variation in operation temperature, giving true ‘multigrade’ characteristics. Outstanding cleanliness and filterability, coupled with excellent water separation, air release and antifoam characteristics, all help contribute to maintaining or enhancing the efficiency of hydraulic systems
• Readily biodegradableShell Naturelle S2 Hydraulic Fluid is biodegradable by exhibiting over 60% biodegradation after 28 days in the OECD 301 B carbon dioxide evolution test.
• Low toxicity towards the environmentShell Naturelle S2 Hydraulic Fluid is classified as ‘not harmful’ to bacteria, algae, freshwater invertebrates, and fish when tested as water-accommodated fractions (WAFs) according to OECD test guidelines.
• Very high renewables contentShell Naturelle S2 Hydraulic Fluid has mean biobased content of 82% (ASTM D 6866).
• Meets requirement of United States Environmental Protection Agency’s (EPA) 2013 vessel general permit (VGP)
• Fluid Compatibility Shell Naturelle S2 Hydraulic Fluid is miscible with mineral oil fluids and most other ester based biodegradable hydraulic fluids. However, in order to ensure that the environmental properties and performance of Shell Naturelle S2 Hydraulic Fluid are maintained, the hydraulic system should be drained and flushed thoroughly when changing fluids. Guidelines on fluid change-over can be found in ISO 15380 Annex A
