The Paratherm™ GLT heat transfer fluid is a thermally stable fluid with an alkylated aromatic based heat transfer fluid formulated for closed-loop liquid-phase heating systems to 550°F; Chemical equivalent and compatible with Therminol® 55.

OPERATING RANGE

FEATURES

• Low temperature pumpability
• Broad compatibility with synthetic aromatics
• Excellent thermal efficiency vs. standard mineral oil HTF’s

APPLICATIONS INCLUDE

• Engineered Wood & Building Materials
• Oil & Gas Processing

THERMALLY STABLE

Paratherm™ GLT Heat Transfer Fluid is a thermally stable fluid that exhibited almost 40% less degradation when exposed to 600°F (316°C) for 500 hours than a widely used competitive fluid. Although very few heaters expose the fluid to the maximum film temperature for extended periods, this level of stability helps insure that your system operates trouble free during operating upsets.

LOW TEMPERATURE CAPABILITY

Minimum startup temperature is a realistic measure of a thermally stable heat transfer fluid’s low temperature capability since 300 cps is the maximum viscosity that a centrifugal pump can handle. Paratherm™ GLT Heat Transfer Fluid has a lower minimum start-up temperature 18°F (-6°C) than any mineral-oil based fluids that cover a similar temperature range.

Performance Data: Paratherm™ GLT vs. Therminol 55

ASTM D6743 – Thermal Stability of Organic Heat Transfer Fluids

Fluid samples held at 316°C (600°F) for 500 hours to assess stability to continuous thermal stress
The total degradation is determined by the total mass percentage of high boilers, low boilers and other decomposition products found in the thermally stressed sample. This value reflects the overall thermal degradation of the stressed fluid as a direct result of thermal stress.
