Technical Data Sheet Shell Lubricants Page 1 of 2 May 2011 Shell Heat Transfer Oil S2 High Performance Heat transfer fluid Shell Heat Transfer Oil S2 is based on carefully selected, highly refined mineral oils chosen for their ability to provide superior performance in indirec t closed fluid heat transfer systems. Applications • Enclosed circulated heat transfer systems for industrial applications such as process industr y, chemical plants, textile producers etc. and in household equipment such as oil filled radiators. Shell Heat Transfer Oil S2 can be used in high temperature continuous heat transfer equipment with the following application limits: Shell Heat Transfer Oil S2 Max. film temperature 340° C Max. bulk temperature 320° C Performance Features and Benefits • Extended maintenance intervals Shell Heat Transfer Oil S2 is based on carefully selected highly refined mineral oils and resists oi l cracking, oxidation and thickening. This provides extended oil life, provided efficient fluid heating and good pump circulation is ensured, such that film temperatures on the heater surface do not exceed th e limits above. • System efficiency Low viscosity enables excellent fluidity and heat transfer over a wide temperature range. Shell Heat Transfer Oil S2 also has a low vapour pressure so resists cracking. This minimises the formation of volatile decomposition products; these would require recovery via expansion chamber and condensate collector • Wear protection Shell Heat Transfer Oil S2 is non-corrosive and has high solvency – this reduces deposit formation by holding oxidation products in solution and keeping internal surfaces of heat exchangers clean. Specification and Approvals Classified as ISO 6743-12 Family Q Meets typically DIN 51522 requirements Advice The life of Shell Heat Transfer Oil S2 depends on t he design and usage of the system. If the system is w ell designed and not subjected to abnormal workloads, the life can be for many years. It is important to monitor oil condition regularly as rates of change in physical characteristics are mor e significant than actual values. The properties that should be monitored are viscosity, acidity, flash p oint ( open and closed) and insolubles content.

Health and Safety Guidance on Health and Safety is available on the appropriate Material Safety Data Sheet which can be obtained from your Shell representative. Protect the environment Take used oil to an authorised collection point. D o not discharge into drains, soil or water.
