Applications

Shell Tellus S4 ME hydraulic fluids are designed to help users improve the energy efficiency of their hydraulic systems without compromising the protection of the system or maintenance procedures of their equipment and operations. Shell Tellus S4 ME has been found to improve energy efficiency in applications such as plastic injection moulding and metal pressing. In addition, Shell Tellus S4 ME is also uses an advanced ashless additive system designed to help equipment service life and lower maintenance costs through providing outstanding wear protection and long oil life capability.

Shell Tellus S4 ME fluids are compatible with seal materials and paints normally specified for use with mineral oils.

• Industrial hydraulic systems

Particularly suitable for those systems with high intensity of hydraulic power usage such as injection moulding and high pressure metal pressing operations and where resistance to high temperatures or long oil life is required.

• Mobile hydraulic systems

Shell Tellus S4 ME is also suitable for use in certain mobile hydraulic fluid power transmission systems and in marine applications and provides superior low temperature fluidity compared to most conventional ISO HM type fluids.

• Environmental impact

Shell Tellus S4 ME oils use an advanced zinc-free (ashless) additive system to help provide reduced environmental impact in the case of leakage or accidental spillage compared to conventional zinc-based hydraulic fluids through the use of ashless anti-wear technology and low sulphur base oils. For further reductions in environmental impact we offer the Shell Naturelle range of reduced environmental impact lubricants.
