Extrotherm oils(Heat transfer oil) have been specially developed for use as heat transfer medium in industrial application. These heat transfer oils possess high viscosity index, excellent thermal and oxidation stability, low volatility and low vapor pressure to give long service life in well designed heat transfer systems. Extrotherm Special heat transfer oil is recommended for well designed heat transfer system operating up to 315⁰C.Thermal oil , thermal oil heater , thermal fluids , transfer fluid , thermal fluid systems , thermal oil system, thermal transfer systems.
Extrotherm oils(heat transfer oil) are recommended as a fluid medium in various types of heat transfer system for indirect or secondary heating in industry. The use of these heat transfer oils,fluids provide rapid heating and greater flexibility in heat transfer systems since they possess high specific heat and better thermal conductivity at all temperatures.
These heat transfer oils,fluids are suitable for use in both, closed as well as open type heat transfer systems. Extrotherm oils have a high resistance to thermal cracking and hence maintain their heat transfer efficiency even when subjected to repeated high and low temperature cycles. The heat transfer system must be thoroughly cleaned and free from contaminants. All traces of dust, rust and residue of welding operations must be removed by flushing. After the flushing oil is drained the system must be free from moisture before it is charged with Extrotherm oils(Heat transfer oil).
