Shell Heat Transfer Oil S2
High-Performance Heat Transfer Fluid
Shell Heat Transfer Oil S2 main applications:
- Enclosed circulated heat transfer systems for industrial applications such as process industry, 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: Max.
Bulk temperature: 320oC
Max. film temperature: 320oC
Shell Heat Transfer Oil S2 is based on carefully selected, highly refined mineral oils chosen for their ability to provide superior performance in indirect closed fluid heat transfer systems.
For open systems we advise you to use an other oil.

Performance, Features & Benefits of Shell Heat Transfer Oil S2
+ Extended maintenance intervals
Shell Heat Transfer Oil S2 is based on carefully selected highly refined mineral oils and resists oil 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 the 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.
