Shell Tellus S2 M

Previous Name: Shell Tellus OilsShell Tellus S2 MIndustrial Hydraulic Fluid• EXTRA PROTECTION• INDUSTRIAL APPLICATIONSShell Tellus S2 M fluids are high performance hydraulic fluids that use Shell’s unique patentedtechnology to provide outstanding protection and performance in most manufacturing andmany mobile equipment operations. They resist breakdown under heat or mechanical stressand help prevent damaging deposit formation that can decrease the efficiency of yourhydraulic power system.Performance Benefits• Long Fluid Life – Maintenance SavingShell Tellus S2 M fluids help extend equipmentmaintenance intervals by resisting thermal andchemical breakdown. This minimizes sludgeformation and provides excellent performance in theindustry standard ASTM D 943 TOST test (TurbineOil Stability Test), providing better reliability andsystem cleanliness.Shell Tellus S2 M fluids also have good stability inthe presence of moisture, which ensures long fluidlife and reduces the risk of corrosion and rusting,particularly in moist or humid environments.• Outstanding wear protectionProven zinc-based anti-wear additives areincorporated to be effective throughout the range ofoperating conditions, including low load and severeduty high load conditions. Outstandingperformance in a range of piston and vane pumptests, including the tough Denison T6C (dry and wetversions) and the demanding Vickers 35VQ25,demonstrates how Shell Tellus S2 M fluids can helpsystem components last longer.• Maintaining system efficiencySuperior cleanliness, excellent filterability and highperformance water separation, air release and antifoamcharacteristics all help contribute tomaintaining or enhancing the efficiency of hydraulicsystems.The unique additive system in Shell Tellus S2 M, incombination with superior cleanliness (meeting therequirements of ISO 4406 21/19/16 class orbetter ex Shell plant filling lines. As recognized byPage 1 of 3Shell LubricantsDIN 51524 specification, the oil is exposed tovarious influences with transport and storagethat could effect the cleanliness level) helpsreduce the impact of contaminants on filterblocking, allowing both extended filter life anduse of finer filtration for extra equipmentprotection.Shell Tellus S2 M fluids are formulated for fastair release without excessive foaming to helpefficient hydraulic power transfer and minimisefluid and equipment impacts of cavitationinducedoxidation that can shorten fluid life.Applications• Industrial hydraulic systemsWith an extensive range of equipment makerapprovals and recommendations, Shell TellusS2 M fluids are suitable for a wide range ofhydraulic power applications found inmanufacturing and industrial environments.• Mobile hydraulic fluid power transmissionsystemsShell Tellus S2 M fluids can be used effectively inmobile hydraulic power applications such asexcavators and cranes, except where significantambient temperature variations are encountered.For these applications we recommend the ShellTellus “V” series.• Marine hydraulic systemsSuitable for marine applications where ISO HMcategory hydraulic fluids are recommended..24/02/2010
