Product Description

Shell Heat Transfer Oil S2 X

High Performance Heat transfer fluid

Shell Heat Transfer Oil S2 X is a premium quality heat transfer fluid for use in indirectly heated closed heat transfer systems. It is based on carefully selected highly refined mineral oils chosen for their ability to provide superior performance in heat transfer systems and contains an oxidation inhibitor to provide long service life.

Applications

• Industrial heat transfer systems For use in closed heat transfer systems used in chemical and process plant, textile manufacture etc. where the oil is circulated in a pumped system operating under atmospheric pressure with or without an inert gas blanket.

Shell Heat Transfer Oil S2 X can be used in high temperature continuous heat transfer equipment with the following application limits:

Max. film temperature 315°C

Max. bulk temperature 290°C

Performance Features and Benefits

• Extended maintenance intervals

Shell Heat Transfer Oil S2 X 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 X 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 X 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 under ISO 6743-12 Family Q Meets DIN 51522 requirements

Advice

The service life of Shell Heat Transfer Oil S2 X depends on the design and operation of the system.

If the system is well designed and not subjected to abnormal workloads, the life can be many years. It is important to monitor oil condition regularly as rates of change in physical characteristics are more significant than actual values. The properties that should be monitored are viscosity, acidity, flash point (open and closed) and insolubles content.
