Shell Tellus Oils T - SwanTek

1 February 2000 UOCS/3 Shell Tellus oils TMultigrade hydraulic oilShell Tellus oils T are premium performance, anti-wear hydraulic oils whichincorporate a special viscosity index improver additive to enhance theirviscosity/temperature Hydraulic and fluid power transmissionsystems subjected to wide variations intemperature, or where low viscositychange with fluctuating temperature isrequired Oil lubricated rolling bearings Lubrication of bearings by the micro-fogtechnique Certain critical hydraulic systems can onlytolerate small variations in viscosity withfluctuating temperature if efficiency andresponsiveness is to be oils such as Shell Tellus oils T,which exhibit multigrade viscositycharacteristics, may be used to particularadvantage in these circumstances.

2 Performance Features Very low viscosity variation withtemperature Special viscosity modifier technologyminimises the oil s variation in viscositywith changes in temperature and providesgood pumpability at low features are particularly beneficial inhydraulic applications subjected toextremes of temperature High shear stability The viscosity modifier is highly resistant tomechanical stress. The maintenance of stay-in-grade characteristics ensureseffective lubrication, efficient systemoperation and long oil life Outstanding anti wear performance Proven anti-wear additives are effective inall operating conditions, including low andsevere duty situations Excellent filterability Minimal tendency to cause filter blockagein the presence of contaminants such aswater and calcium Oxidation resistant Resists the formation of acidic productsand sludge.

3 Even at high workingtemperatures Corrosion protection Powerful inhibitors provide long termprotection against corrosion of both ferrousand most non-ferrous metals Rapid air release and anti-foam propertiesProvide rapid air release without excessivefoamingCompatibilityThe anti-wear additive technology used inShell Tellus oils T is based upon zinc which,although ideal for most hydraulic pumps,should not be used in those of older designcontaining silver plated components. ShellTellus oils S should be used for & SafetyShell Tellus oils T are unlikely to present anysignificant health or safety hazard when properlyused in the recommended application, and goodstandards of industrial and personal hygiene further guidance on Product Health & Safetyrefer to the appropriate Shell Product Safety DataSheet.
