Heat Transfer Fluids

Therminol® VP-1

Eastman Chemical

Therminol VP-1 heat transfer fluid is an ultrahigh-temperature synthetic heat transfer fluid designed to meet the demanding requirements of vapor-phase systems or liquid-phase systems.

Temperature Range
+12 °C to +400 °C

Performance Benefits
• Superb Heat Transfer Properties - Therminol VP-1 is a synthetic heat transfer fluid which combines exceptional thermal stability and low viscosity for efficient, dependable, uniform performance in a wide optimum use range of 12° to 400°C (54° to 750°F ). Therminol VP-1 has the highest thermal stability of all organic heat transfer fluids.
• Low Viscosity - Therminol VP-1 has a low viscosity to 12°C (54°F). Because of its crystallization point of 12°C (54°F), this fluid may require tracing in colder climates to avoid operational problems.
• Vapor Phase Heat Transfer Fluid - 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.
• Precise Temperature Control - Due to its ability to operate as a vapor-phase heat transfer fluid, Therminol VP-1 is excellent for use in heat transfer fluid systems requiring very precise temperature control.
