Thermal oil is a type of heat transfer fluid used in various industrial applications. It is designed to operate at high temperatures while maintaining stable viscosity and thermal properties. Commonly used in processes like heating, cooling, and energy generation, thermal oil helps efficiently transfer heat in systems such as solar thermal plants and chemical reactors. Unlike water, thermal oil can reach higher temperatures without boiling, making it suitable for applications that require consistent heat. It is often made from synthetic or mineral oils, which provide excellent thermal stability and resistance to oxidation. This makes thermal oil a reliable choice for industries like food processing and petrochemicals.
