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.
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 below.
Low viscosity enables excellent fluidity and heat transfer over a wide temperature range. Shell Heat Transfer Oil S2 X 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.
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.
