Armcoltherm 400 (12~400℃)Heat Transfer Fluid With a freezing point of 12°C and a boiling point of 257°C under normal atmospheric conditions, this synthetic heat transfer oil is renowned as the earliest of its kind, offering a broad range of industrial applications. Boasting a maximum temperature capability of 400°C, it exhibits exceptional thermal stability and heat transfer performance. Armcoltherm 400 thermal oil is ideally suited for liquid phase heating systems operating between 12°C and 400°C, as well as gas phase heating systems operating between 257°C and 400°C. Its primary use lies in high-temperature heat transfer applications, including polyester, nylon, and polypropylene chemical fiber polymerization, spinning, and texturing machines. Additionally. It finds utility in the production of naphthalene phthalic anhydride, melamine, and polyoxymethylene, as well as CPS solar thermal power generation.
