Therminol® 54 Heat Transfer Fluid
Description
Therminol 54 is a synthetic fluid designed to serve reliable, consistent heat transfer performance over a long service life at maximum bulk temperatures up to 280°C (540°F). Therminol 54 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.
Performance Benefits.
- Excellent pumpability—Therminol 54 supports operations with temperatures lower than possible with many other mineral oils.
- Non-sludge-producing chemistry—The use of Therminol 54 enables life-cycle operational cost efficiencies, including optimal pump seal life, fewer system cleanings between refills, and longer fluid life.
- Excellent resistance to fouling—Therminol 54 is a synthetic fluid, it refrain the effects of oxidation 10 times better than mineral oils.
