Description:

 Performance hydraulic oils for wide temperature ranges.

Shell Tellus Oils T are premium quality hydraulic oils generally acknowledged to be the 'standard-setter' in the field of industrial hydraulic and fluid power lubrication.

They incorporate a Shell patent antiwear technology and a shear stable viscosity index improver to enhance and maintain excellent viscosity/temperature characteristics.  

Applications:

• Hydraulic and fluid power transmission systems subjected to wide variations in temperature or where low viscosity change with fluctuating temperature is required.

Certain critical hydraulic systems can only tolerate small variations in viscosity with fluctuating temperature if efficiency and responsiveness are to be maintained. Hydraulic oils, such as Shell Tellus Oil T, which exhibit multigrade viscosity characteristics may be used to particular advantage in these circumstances.

If even further limited viscosity variations are required Tellus Oils STX should be considered. 

Performance Features And Benefits:

• Wide operating temperature range
The use of selected viscosity index improver reduces the viscosity variation with temperature allowing the systems to operate in a wide oil temperature range with more consistent performances. Reasons for oil temperature modification could be different ones like: environment temperature variation, intermediate working condition or variable workload

• Maintained viscosimetric characteristics unchanged with time
The high shear stability of the viscosity index improver used allows to retain the original viscosimetric characteristics preventing the oil to get thinner and thinner at high temperature and therefore preventing the reduction of the max operating temperature and the system efficiency.

• Outstanding anti-wear performance
Proven and patent anti-wear additives are incorporated to be effective throughout the range of operating conditions, including low and high load conditions. Outstanding performance in a range of piston and vane pump tests have been obtained including the newest Denison T6H (the so called hybrid pump), the tough Denison T6C (dry and wet versions) and the demanding Vickers 35VQ25. Tellus T help system components last longer.

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

• Superior filterability
Tellus T are suitable for ultra-fine filtration, an essential requirement in today's hydraulic systems. They are 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.

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

• Thermal stability
Thermally stable in modern hydraulic systems working in extreme conditions of load and temperature. Tellus T are highly resistant to degradation and sludge formation therefore improving system reliability and cleanliness.
