Heat Transfer Fluid
A variety of types of heat transfer fluid
Heat transfer fluid, also known as heat transfer fluid (HTF), is a specialized liquid engineered to transfer thermal energy in industrial heating systems. Unlike water or steam, thermal oils operate at elevated temperatures (typically up to 400°C) without vaporizing, maintaining stable liquid-phase heat transfer. This characteristic makes them ideal for closed-loop systems requiring precise temperature control and uniform heat distribution. Modern thermal oils are formulated from highly refined mineral oils or synthetic compounds (such as alkylbenzenes or diphenyl oxides) to deliver superior thermal stability, oxidation resistance, and extended service life. Their applications span diverse industries including chemical processing, pharmaceutical manufacturing, food production, and renewable energy systems, where they enable efficient indirect heating while minimizing system corrosion and maintenance requirements.
