Manufacturer's description

Environmentally Acceptable, Synthetic Hydraulic Fluid. Shell Naturelle S2 Hydraulic Fluid is an advanced hydraulic fluid for use in hydraulic and power transmission systems. Readily biodegradable with low ecotoxicity, Shell Naturelle S2 Hydraulic Fluid is particularly suited for use in environmentally sensitive areas. Fully synthetic esters, blended with ashless additives, provide Shell Naturelle S2 Hydraulic Fluid with an excellent blend of lubrication performance and environmental acceptability.

Applications

• Less FlammableShell Naturelle S2 is a less flammable hydraulic Fluid with high flash point.
• 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 biodegradable & Low EcotoxicityShell 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 USDA Bio-preferred programme Meets requirements of EU Ecolabel certificate number NL/027/019
• 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

Standards & approvals

• ISO 15380 HEES

  Biodegradable hydraulic fluid HEES — ISO 15380

  The international standard for biodegradable hydraulic fluids; class HEES is the synthetic ester type, the most used where a leak would reach water or soil.

• SS 15 54 34 SP

  SS 15 54 34 — environmental requirements for hydraulic fluids (Sweden)

  The Swedish standard requiring high biodegradability, low aquatic toxicity, and that the finished fluid not be classified as environmentally hazardous. It is required near groundwater and drinking water sources; verified products appear on the "SP list".

• ISO 12922 HFDU

  ISO 12922 HFDU — fire-resistant hydraulic fluid

  Class HFDU of ISO 12922: water-free, fire-resistant synthetic hydraulic fluids for foundries, steel plants and mines.

• OECD 301B

  OECD 301B biodegradability above 60 %

  A test result rather than a norm: OECD 301B measures the carbon dioxide evolved over 28 days. Above 60 % counts as "readily biodegradable", the threshold the environmental labels require.
