Eastman Therminol 54 Heat Transfer Fluid- –28° to 280° C

Eastman Therminol® 54 heat transfer fluid is a synthetic fluid designed to provide reliable, consistent heat transfer performance over a
long service life at maximum bulk temperatures up to 280°C (540°F).
Therminol 54 fluid provides an excellent alternative to mid-temperature, mineral oilbased fluids by capturing the performance and
nonfouling attributes highly desired of synthetic fluids.

Therminol 54 fluid is designed for use in nonpressurized/ low-pressure, indirect heating systems. It delivers efficient,
dependable, uniform process heat with no need for high pressures.
The high boiling point of Therminol 54 helps reduce the volatility and fluid leakage problems associated with other fluids.
The recommended maximum bulk and film temperatures for Therminol 54 are based on industry-standard thermal studies.
Operation at or below these temperature maximums can provide long service life under most operating conditions.
Actual fluid life is dependent on the total system design and operation and can vary by heat transfer fluid chemistry. As fluid
ages, the formation of low- and high-boiling compounds may result. Low-boiling compounds should be vented from the system
as necessary to a safe location away from personnel and sources of ignition and in compliance with applicable regulations and
laws. The high-boiling compounds can be very soluble in the fluid.
Significant overheating or fluid contamination will accelerate decomposition and may result in increased high-boiler and solids
concentrations. Excess solids can typically be filtered for removal.
