The requirements for heat transfer oils are widely spread and mainly depend on each individual application. To name would be the good thermal stability and low viscosity, a highest possible flash point as well as good heat transfer properties. Besides of this, the heat transfer medium should not be corrosive or toxical, have a low flammability and be easy to dispose.
Consider entire life cycle
Also the profitability must be right. In former years, it was often only looked at the acquisition costs for the heat transfer oil, today the costs for the entire life cycle of the heat transfer medium are regarded. High quality heat transfer oils are at an advantage since they are thermally more stable and have a higher service life.
Furthermore, decisive for the profitability are good heat transfer properties and a low viscosity to keep the required driving power of the circulation pumps low.
Another important aspect for the profitability of plants are undesired production failures as well as unplanned maintenance and repair work. Here too high quality heat transfer oils have a clear advantage.
Keep an eye on productivity
The choice of the correct heat transfer medium can significantly shorten also production processes. High quality oils can shorten for example the cycle times in the chemical industry. Also increases in temperature that are possible with the use of higher quality oils can lead to increases in productivity.
Admittedly: The choice of the correct heat transfer medium is not always easy due to the variety of available products. Therefore the involvement of a specialized company or the advice by the manufacturing companies or the trade is well worth in any case.
