Therminol 59 is a synthetic heat transfer fluid with excellent low temperature pumping characteristics (to -50° F or -45° C) and thermal stability to 600° F (315° C). Performance features of Therminol 59 include:
|
- 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 70° F (20° C). 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 - Like all the Therminol heat transfer fluids, long fluid life is a given with Therminol 59. Users can expect many years of reliable, trouble-free operation, even when operating continuously at the recommended upper temperature limit of 600° F (315° C). Long life means fewer fluid change-outs and that means low operating costs, which is critical in today’s highly competitive business environment.
Therminol 59 is used in a wide variety of industries, such as:
- Oil and Gas Processing
- Switch Condensers
- Pharmaceuticals Manufacturing
- Specialty and Batch Chemical Production
- Biodiesel
