1 Typical physical characteristics Technical Data SheetPrevious name : Shell Thermia CShell heat transfer Oil S2 XReliable performance High performance heat transfer FluidShell heat transfer Oil S2 X is a premium quality heat transfer fluid for use in indirectly heated closed HeatTransfer systems. It is based on carefully selected highly refined mineral oils chosen for their ability to providesuperior performance in heat transfer systems and contains an oxidation inhibitor to provide long service , Features & BenefitsExtended maintenance intervals Shell heat transfer Oil S2 X is based on carefully selectedhighly refined mineral oils and resists oil cracking, oxidationand thickening. This provides Extended oil life, providedefficient fluid heating and good pump circulation is ensured,such that film temperatures on the heater surface do notexceed the limits efficiency Low viscosity enables excellent fluidity and heat transferover a wide temperature range.

2 Shell heat transfer Oil S2X also has a low vapor pressure so resists cracking. Thisminimizes the formation of volatile decomposition products;these would require recovery via expansion chamber andcondensate protection Shell heat transfer Oil S2 X is non-corrosive and has highsolvency this reduces deposit formation by holdingoxidation products in solution and keeping internal surfacesof heat exchangers ApplicationsIndustrial heat transfer systems For use in closed heat transfer systems used in chemicaland process plant, textile manufacture etc. where the oil iscirculated in a pumped system operating under atmosphericpressure with or without an inert gas heat transfer Oil S2 X can be used in HighTemperature continuous heat transfer equipment with thefollowing Application limits:Max. film temperature : 3150 CMax. bulk temperature : 2900 CSpecifications, Approvals & RecommendationsClassified under ISO 6743-12 Family Q Meets DIN 51522 requirements For a full listing of equipment approvals andrecommendations, please consult your local Shell transfer Oil S2 XISO Viscosity GradeISO 344868density@150 Ckg/m3 ISO 12185865 Flash Point (COC)0 CISO 2592260 Pour Point0 CISO 3016-6 Kinematic Viscosity@400 Cmm2/sISO Viscosity@1000 Cmm2/sISO IndexISO 290996 Neutralization Valuemg KOH/gASTM D974< Content% m/mISO 3733< 1 of 2 heat transfer Oil S2 X, v characteristics are typical of current production.

Use impervious gloves with used oil. After skin contact, wash immediately with soap and on Health and Safety is available on the appropriate Material Safety Data Sheet, which can be obtained the Environment Take used oil to an authorized collection point. Do not discharge into drains, soil or InformationAdvice The service life of Shell heat transfer Oil S2 X depends on the design and operation of the system.

4 If the system is welldesigned and not subjected to abnormal workloads, the life can be many is important to monitor oil condition regularly as rates of change in physical Characteristics are more significant than actualvalues. The properties that should be monitored are viscosity, acidity, flash point (open and closed) and insolubles recommendations for applications and specifications not covered here may be obtained from your 2 of 2 heat transfer Oil S2 X, v
