Description
Eastman Therminol® FF flushing fluid is a key component of a low-cost alternative to chemically cleaning a heat transfer system containing severely degraded or contaminated organic heat transfer fluid. Deposits from oxidized, thermally degraded, or contaminated fluid can foul interior surfaces, making it necessary to clean the system prior to charging with new fluid. Therminol FF is available globally. Contact your local Eastman Therminol sales representative for more information.
- Fast and easy
Using Therminol FF to flush your fouled system is faster than chemical cleaning and requires less downtime. This is because you simply drain the old fluid, add Therminol FF, circulate the heated fluid, and drain and refill with your new heat transfer fluid
- Compatible with system components
Mechanical components used in most high-temperature heating systems which use organic heat transfer fluids are generally compatible with Therminol FF. This includes piping, flanges, gaskets, pumps, valves and valve packing, filters, and insulation. Using Therminol FF as a cleaning fluid should not compromise performance or cause harm to the integrity of these system components. A bulletin showing specific compatibility ratings with common materials is available.
- Compatible with new heat transfer fluid
Therminol FF is compatible and miscible with most organic heat transfer fluids, which means less downtime is required for system cleaning. Water-based cleaning solutions add costly drying time to a cleanout procedure, creating additional chances for contamination. Therminol FF eliminates drying time, thus significantly reducing the duration of the procedure. The system can be refilled immediately.
- Safe and effective
Therminol FF is a synthetic hydrocarbon with a high flash point and high initial boiling point, making it much safer to use than other cleaning solvents. Due to its high boiling point, Therminol FF can be safely heated while circulating in the system to increase its strong solubilizing capacity and overall effectiveness as a cleaning fluid.

- Heat transfer system cleaning with Therminol FF
When performance of a heat transfer system decreases due to fouling or the solids level in the fluid is too high for effective filtration, a cleanout may be necessary to restore the system to peak operating performance. Sludge and solids are often the result of process contamination or decomposition of the heat transfer fluid through oxidation or overheating. To help you decide on the correct cleanout procedure, Eastman can provide a no-charge fluid analysis to determine the extent of degradation or contamination. These test results can then be used in developing the parameters required to maximize the effectiveness of Therminol FF as a cleaning fluid in your system. A general system cleaning procedure follows, but each system and situation can be different. Consultation with your Therminol specialist and system designer is recommended while planning the cleaning of a heat transfer fluid system.
