    • Therminol® 54 – synthetic thermal oil

    Therminol® 54 is a synthetic fluid designed to ensure reliable and consistent heat transfer performance over a long service life at maximum operating temperatures in thermal oil systems.

    Due to its excellent price-performance ratio, Therminol® 54 is an alternative to mineral oil-based heat transfer fluids.

    Your advantages of using Therminol® 54 in your thermal oil systems:

    • excellent pumpability – Therminol® 54 can operate at lower temperatures than many other mineral oils. 

    • no sludge-forming chemistry – using Therminol® 54 results in cost savings over the fluid's entire lifecycle, including optimal pump seal life, fewer system cleanings between refills, as well as fluid longevity. 

    • excellent contamination resistance – as a synthetic fluid, Therminol® 54 withstands oxidation impacts 10 times better than mineral oils. 

    Discover a wide range of the most common applications for Therminol® 54:

    • asphalt processing and storage

    • plastics and polymer manufacturing

    • chemical manufacturing

    • food and beverage production

    • Medium Density Fiberboard (MDF)
