• Peformance Features
  Good low temperature properties
  Shell Thermia Oil B is fluid down to -18°C.
  Therefore no special precautions are
  necessary when closing down plant in cold
  weather. Should the temperature fall below
  -18°C no expansion takes place.
• Low vapour pressure
  Below temperatures of 320°C, the vapour
  pressure of Thermia B is less than
  atmospheric pressure. High pressure
  pipework and heat exchangers, used with
  vapour phase heat transfer fluids, are
  therefore unnecessary.
• Good heat transfer characteristics
  Shell Thermia Oil B has a relatively low
  viscosity with good temperature/viscosity
  characteristics which ensure high heat
  transfer coefficients and consistent
  properties cover a wide temperature range.

Performance Benefits:
• Low cost
• High thermal stability
• Operating temperature range from -18°C to
+ 320°C.
• Good oxidation stability
• Low viscosity to promote high heat transfer
coefficients
• Good viscosity/temperature characteristics
• Low vapour pressure
• Non-corrosive
• Non-toxic
