Shell Naturelle S2 Hydraulic Fluid 32, 46, 68

·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) ofShell Naturelle S2 Hydraulic Fluid 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, 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 900C.

·Environmentally sensitive areas
Shell Naturelle S2 Hydraulic Fluid is an ‘environmentally acceptable’ hydraulic fluid (ISO 15380 HEES). 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.

Compatibility & Miscibility
·Fluid Compatibility
Shell Naturelle S2 Hydraulic Fluid is miscible with mineral oil 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. Owing to the surface-wetting properties of Shell Naturelle S2 Hydraulic Fluid, 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 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.
