Therminol VP-1

Product Description

Tru-Blu Oil supplies the Therminol ® range of synthetic heat transfer fluids manufactured by Eastman Chemical Company through-out Australia.

Therminol heat transfer fluids can meet the operating needs of virtually any heat-using system. All Therminol products provide superior benefits of economy, efficient operation, minimum maintenance and precise temperature control. In properly designed systems, Therminol heat transfer fluids will perform within their respective temperature ranges for extended periods without breakdown or corrosion.

Therminol VP-1 heat transfer fluid is an ultra-high temperature synthetic heat transfer fluid designed to meet the demanding requirements of vapour phase systems or liquid phase systems. Therminol VP-1 has the highest thermal stability of all organic heat transfer fluids.

Therminol VP-1 is a eutectic mixture of diphenyl oxide (DPO) and biphenyl. It can be used as a liquid heat transfer fluid or as a boiling-condensing heat transfer medium up to its maximum use temperature. It is miscible and interchangeable for top-up or design purposes with other similarly constituted diphenyl-oxide (DPO) biphenyl fluids. Due to its ability to operate as a vapour phase heat transfer fluid, Therminol VP-1 is excellent for use in heat transfer fluid systems requiring very precise temperature control.

Therminol VP-1 has a low viscosity to 12c. Because of its crystallization point of 12c this fluid may require tracing in colder climates to avoid operational problems.


Therminol VP-1 is used in a wide variety of industries such as:

  • Gas to Liquid
  • Synthetic Fibre Manufacturing
  • Chemical Manufacturing
  • Concentrated Solar Power
  • Biofuel Manufacturing
