Applications

 N/A Enclosed circulated heat transfer systmes 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 film temperature - 320 C
  • Max bulk temperature - 300 C

Features and Benefits

 N/A 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 below.

System Efficiency - Low viscosity enables excellent fluidity and heat transfer over a wide temperature range. Shell Heat Transfer Oil S2 also has a low vapor pressure so resists cracking. This minimizes 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.

Additional Information

 N/A The life of Shell Heat Transfer Oil S2 depends on the design and usage of the system. If the system is well 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 more significantly than actual values. The properties that should be monitored are viscosity, acidity, flash point (open and closed) and insolubles content.
