Shell Naturelle S2 Hydraulic Fluid 46 is an advanced biodegradable and HFDU type less flammable hydraulic fluid for use in hydraulic and power transmission systems. It is readily biodegradable with a low ecotoxicity, particularly suited for use in environmentally sensitive areas and in industrial equipment operating in areas subject to fire hazards, such as as in steel mills, surface mines, and foundries. Fully synthetic esters, blended with ashless additives, provide Shell Naturelle S2 Hydraulic Fluid 46 with a superior blend of lubrication performance and environmental acceptability.

Applications

 N/A Mobile/Exterior Hydraulic Applications - Hydraulic and fluid power transmission systems in exposed environments can be subject to wide variations in temperature. The naturally high, shear stable viscosity index (VI) of Shell Naturelle S2 Hydraulic Fluid 46 helps deliver responsive performance from cold start to full load, heavy duty operation.

General Industrial Control Equipment and Hydraulic Systems - The excellent anti-wear properties and high viscosity index (VI) of Shell Naturelle S2 Hydraulic Fluid 46, mean that it can often be used where ISO 11158 (HM/HV) and DIN 51524 Part 2 or Part 3 (HLP/HVLP) mineral oil hydraulic fluids are specified. However, bulk fluid operating temperatures should not be allowed to exceed 90 C.

Environmentally Sensitive Areas - Shell Naturelle S2 Hydraulic Fluid 46 is an 'environmentally accpetable' hydraulic fluid (ISO 15380 HEES), with 'reduced harm for water and soil during use' (European Union 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, and meets the United States Environmental Protection Agency's (EPA) 2013 Vessel General Permit (VGP) requirements for use in marine applications.

Industrial Operation Subject to Fire Hazards - Shell Naturelle S2 Hydraulic Fluid 46 is classified as an HFDU type fire-resistant hydraulic fluid for use in industrial equipment operating in areas subject to fire hazards, such as in steel mills, surface mines, and foundries. It has a high ignition temperature and heat release.

Features and Benefits

 N/A Excellent Wear Protection - Advanced ashless (zinc-free) anti-wear additives provide protection over a wide range of conditions - proven protection in tough industry standard tests such as the Eaton Vikcers 35VQ25 vane pump and Komatsu HPV35+35 high pressure piston pump.

Maintaining System Efficiency - Excellent viscosity/temperature characteristics can minimuze the changes of viscosity with variation in operation temperature, giving true 'multigrade' characteristics. Superior cleanliness and filterability; coupled with excellent water separation, air release and anti-foam characteristics, all help maintain or enhance hydraulic system efficiency. The filterability of Shell Naturelle S2 Hydraulic Fluid 46 is maintained, even when the fluid is contaminated with water. 

Readily Biodegradable - Shell Naturelle Fluid S2 Hydraulic Fluid 46 contains a mean biobased content of over 80% (ASTM D6866) and is biodegraded by over 60% after 28 days in the OECD 301 B carbon dioxide evolution test. The fluid is classified as 'not harmful' to bacteria, algae, freshwater and marine invertebrates, and fish when tested as water-accommodated fractions (WAFs) according to OECD and EPA test guidelines.

Lox Toxicity Towards the Environment - Shell Naturelle S2 Hydraulic Fluid 46 is less flammable hydraulic fluid with high flash point, fire point and autoignition temperature for reduced risk of fire/explosion.

Additional Information

 N/A Fluid Compatibility - Shell Naturelle S2 Hydraulic Fluid 46 is miscible with mineral oil hydraulic fluids. However, in order to ensure that the environmental properties and performance of Shell Naturelle S2 Hydraulic Fluid 46 is 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. Owing to the surface-wetting properties of Shell Naturelle S2 Hydraulic Fluid 46, if the system was previously operated using a mineral oil hydraulic fluid, deposits formed in the system during operation may be loosened and deposited in the system filters. The filters should therefore be checked at regular intervals after fluid change-over.

Seal & Paint Compatibility - Shell Naturelle S2 Hydraulic Fluid 46 is compatible with hydrogenated nitrile (HNBR) and fluoroelastomers (FPM/FKM) such as Viton. Depending on the elastomer grade, it is also compatible with polyester urethane (AU) elastomers. Other seal materials and system components such as paints may be adversely affected and advice should be sought from the respective manufacturers.
