Shell Naturelle S2 HF 32

Specifications, Approvals & Recommendations of Shell Naturelle HF-E 32

Shell Naturelle HF-E 32 Main Applications

+ 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 Fluid HF-E 32 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 Fluid HF-E 32, 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 0 allowed to exceed 90 C.

+ Environmentally sensitive areas

Shell Naturelle Fluid HF-E 32 is an ‘environmentally acceptable’ 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 HF-E 32 Fluids are classified as HFDU type fire-resistant hydraulic fluid for use in industrial equipment

Shell Naturelle HF-E 32 benefits:

• + Excellent wear protection
• + Maintaining system efficiency
• + Readily biodegradable & Low Ecotoxicity
• + Fire Resistance
• + Fluid Compatibility
• + Seal & Paint Compatibility

Compatibility and Miscibility

Compatibility with oils

Shell Naturelle Fluid HF-E 32 can be mixed with mineral hydraulic oils. However, to indicate that the biodegradable properties and proper functioning are maintained when men switch to a different fluid, it is necessary that the hydraulic systems are properly drained and flushed.
Guidelines for an oil change can be found in ISO 15380 Appendix A. Shell Naturelle Fluid HF-E 32 can cause old deposits to come loose during use, especially if the system previously operated on mineral hydraulic oil. It is therefore important to check the filters on a comparable basis after the transition to Shell Naturelle HF-E 32.

Compatibility of seals and coatings

Shell Naturelle Fluid HF-E 32 is compatible with hydronated nitrille (HNBR) and with fluoro sealing materials (FPM / FKM) such as Viton®. Depending on the elastomer degree, it is also compatible with polyester urethane (AU) elastomers.
Other sealing materials and components such as paint, on the other hand, can be affected and we therefore recommend that you consult the respective constructors.
 

Performance, Features & Benefits of Shell Naturelle HF-E 32

+ 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 Vickers 35VQ25 vane pump and Komatsu ·HPV35+35 high-pressure piston pump.

+ Maintaining system efficiency

Excellent viscosity/temperature characteristics can minimize 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 to maintain or enhance hydraulic system efficiency. The filterability of Shell Naturelle Fluid HF-E 32 is maintained, even when the fluid is contaminated with water.

+ Readily biodegradable & Low Ecotoxicity

Shell Naturelle Fluid HF-E 32 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.

+ Fire Resistance

Shell Naturelle Fluid HF-E 32 is less flammable hydraulic fluid with a high flash point, fire point and autoignition temperature for reduced risk of fire/explosion.
