Eiffel Thermic Fluid series are high performance heat transfer oils formulated with highly refined base stocks, intended for use in closed and indirect heating installations. They provide exceptional resistance to thermal cracking and chemical oxidation, thus flash point of these oils will not decrease significantly in service. Moreover, they are thermally stable and are capable of an extremely long service oil life, without deposit formation or increase in viscosity.Features & Benefits
- Outstanding thermal & oxidation stability prevents coke, varnish & sludge formation and helps in extending life of oil.
- Good low temperature fluidity , facilitates easy starting of cold systems
- Excellent anti-foaming characteristics, avoids pump cavitation and eratic operations.
- High heat transfer rates and improved operating efficiency promotes low cost of operation.
- Excellent protection from rust and corrosion of multi-metallurgy heat exchangers.
- Eiffel Thermic Fluid series can be used in open and closed installations where the bulk oil temperature ranges are outlined as below and where minimum shutdown temperatures are not below -12°C.
- Bulk Oil Temperature Ranges for Closed Systems (-12°C to 310°C) & Open Systems (-12°C to 180°C).
- Suitable for Closed, cold-oil sealed, indirect heating and cooling systems in all kinds of industrial processes operating at bulk oil temperatures up to the maximum temperatures as stated above and at atmospheric pressures.
- Suitable for Open systems, provided the bulk oil temperatures do not exceed the maximum temperatures as stated above.
