DOWTHERM A is widely used as a heat transfer fluid in industrial heating systems. It is especially suited for use in closed-loop systems where consistent and efficient thermal performance is required over a wide temperature range. Common applications include chemical processing, rubber and plastic manufacturing, and oil refining. Its stable thermal properties make it ideal for both liquid phase and vapor phase heat transfer operations. DOWTHERM A is also used in high-temperature processes such as thermal curing, drying, and distillation due to its ability to operate at elevated temperatures without significant degradation. Its low vapor pressure at operating temperatures enhances system safety and efficiency.
