Shell Tellus Oils

High Performance Hydraulic Oil

Shell Tellus Oils Applications:
• Industrial hydraulic systems
• Mobile hydraulic fluid power transmission systems
• Marine hydraulic systems


Shell Tellus Oils Performance Features and Benefits:
Thermal stability
Thermally stable in modern hydraulic systems working in extreme conditions of load and temperature. Tellus Oils are highly resistant to degradation and sludge formation therefore improving system reliability and cleanliness.

Shell Tellus Oils Oxidation resistant
Resist oxidation in the presence of air, water and copper. Turbine Oil Stability
Test (TOST) results show outstanding performance for Tellus Oils; low acidity,
low sludge formation, low copper loss; therefore extending oil drain interval life
and minimising maintenance costs.

Shell Tellus Oils Hydrolytic stability
Tellus Oils have good chemical stability in the presence of moisture, which ensures long oil life and reduces the risk of corrosion and rusting.

Shell Tellus Oils Outstanding anti-wear performance
Proven anti-wear additives are incorporated to be effective throughout the range of operating conditions, including low and severe duty high load conditions. Outstanding performance in a range of piston and vane pump tests; including the tough Denison T6C (dry and wet versions) and the demanding Vickers 35VQ25.
Tellus Oils help system components last longer.

Superior filterability
Tellus Oils are suitable for ultra-fine filtration, an essential requirement in
today's hydraulic systems. Unaffected by the usual products of contamination, such as water and calcium, which are known to cause blockage of fine filters. Customers can use finer filters, therefore achieving all the benefits of having in use cleaner fluids.

Low friction
Tellus Oils possess high lubrication properties and excellent low friction
characteristics in hydraulic systems operating at low or high speed. Prevents
stick-slip problems in critical applications enabling very fine control of machinery.

Excellent air release and anti-foam properties
Careful use of additives to ensure quick air release without excessive foaming.
Quick air release helps minimise cavitation and slow oxidation, maintaining
system and fluid performance.

separation
Good water separation properties (demulsibility). Resists the formation of
water-in-oil emulsions and prevents consequent hydraulic system and pump
damage.

All round versatility
Tellus Oils are suitable for a wide range of other industrial applications.
