Diphyl-THT Heat Transfer Fluid

Diphyl THT Heat Transfer Fluid is a superior heat-resistant synthetic HTF known for its clear, colorless pale yellow liquid form. Its exceptional thermal stability, derived from a polyphenyl structure (partially hydrogenated terphenyls), ensures a prolonged working life. This unique composition makes it an ideal choice for demanding heat transfer applications.

The high boiling temperature of Diphyl THT Heat Transfer Fluid allows for its utilization in non-pressure systems across its working range. This characteristic of Diphyl THT Heat Transfer Fluid enhances its versatility, making it suitable for a wide range of applications without the need for pressurized systems.

Diphyl THT Heat Transfer Fluid has a broad application range, spanning from 0 °C to 345 °C. It finds widespread use in various processes within the chemical and petrochemical industry, including reactors, polymerization processes, distillation columns, and machinery for the production of synthetic resins, plastic raw materials, polyester films, fibers, and more. Additionally, it is employed for energy recovery in waste heat processes in the steel and petrochemical industries.

To maintain optimal performance, it’s crucial to ensure that the film temperature of Diphyl THT Heat Transfer Fluid does not significantly exceed the 370 °C limit and is within an acceptable range. Operators should monitor and control the working conditions to prevent prolonged exposure to high temperatures.

Yes, Diphyl THT Heat Transfer Fluid is commonly used in the production of chemicals like PBT, PET, and purified terephthalic acid (PTA). Its application is prevalent in fiber spinning mills globally, showcasing its effectiveness in critical processes within the chemical and petrochemical industries.
