Heat Transfer Fluids

Therminol® 59

Eastman Chemical

Therminol 59 is a synthetic heat transfer fluid with excellent low-temperature pumping characteristics and thermal stability.

Temperature Range
 -49 °C to +315 °C

Performance Benefits
• Heating or Cooling Operation - Therminol 59 has surprisingly low viscosity for a high-temperature heat transfer fluid. It is ideally suited for combination heating and cooling applications, delivering excellent heat transfer rates even at 20°C (70°F). Batch processes will benefit from the excellent cooling performance Therminol 59 delivers.
• Superb Low Temperature Pumpability - Low viscosity at exceptionally cold temperatures makes this an ideal fluid for northern climates. In fact, Therminol 59 was originally developed for use on the North Slope in Alaska, a supreme test of low temperature pumpability.
• Long Life Means Low Cost - Users can expect many years of reliable, trouble-free operation even when operating continuously at the recommended upper temperature limit of 315°C (600°F ). Long life means fewer fluid change-outs and that means low operating costs, which are critical in today’s highly competitive business environment.
