Heat Transfer Fluids

Therminol® 55

Eastman Chemical

Therminol 55 is a synthetic heat transfer fluid used in moderate-temperature applications.
Therminol 55 fluid is designed for use in non-pressurized low-pressure, indirect heating systems. It delivers efficient, dependable, uniform process heat with no need for high pressures.

Temperature Range
 -28 °C to +290 °C

Performance Benefits
• Long Life - You will get years of reliable, cost-effective performance even when operating your system continuously at 290°C (550°F). This means you do not have to over specify your fluid.
• Excellent resistance to fouling - Because Therminol 55 is a synthetic fluid, it resists the effects of oxidation 10 times better than mineral oils making less oxidation and solids formation. For systems without nitrogen inerting, the performance advantages are significant.
• Excellent Low-Temperature Pumpability - Therminol 55 is still pumpable at -28°C (-18°F ), compared to some mineral oils that will not pump at temperatures below -7°C (20°F ). With Therminol 55, your heat transfer fluid system can start up quickly and easily.
