HR synthetic-aromatic heat transfer fluid is an alkylated-aromatic based heat transfer fluid formulated for closed-loop liquid phase heating to 650°F in fired heaters and 675°F in waste heat recovery and full convection heaters. HR synthetic-aromatic thermal fluid offers greater thermal stability than competitive aromatic based fluids that cover similar temperature ranges. Testing (ASTM D6743) shows that, compared to its closest competitor, HR synthetic-aromatic heat transfer fluid experiences 1/2 the amount of fluid degradation when maintained at 700°F for 500 hours. Less degradation means less maintenance and a longer fluid life. Centrifugal pumps are generally specified around the fluid viscosity at the desired operating temperature (usually less than 2 cps). Capacity falls off significantly above 300 cps. So the actual minimum start-up temperature of a fluid is where the viscosity curve crosses the 300 cps line. HR Synthetic-Aromatic Heat Transfer Fluid’s lower cold start-up temperature of 13°F (-11°C) offers a significant advantage over other high-temperature fluids.

Note: If you are experiencing short supply, or long lead times for your currently specified synthetic/aromatic 650°F (terphenyl or alkylated aromatic) heat transfer fluid, call Paratherm for a point-by-point comparison of physical properties. We have product available, and may have just the fluid for your application. +1 (610) 860-6323. Or, use the links on the left side of this page to compare properties with Therminol 66.

**The Degree of Decomposition, measured through ASTM D6743, reflects the overall thermal degradation of a thermally stressed fluid at a specific test temperature. It is determined by adding the total mass percentage of all decomposed products found in a thermally stressed sample. These values were found after both fluids were tested side-by-side at 370oC (698oF) for 500 continuous hours. A lower Degree of Decomposition reflects superior relative Thermal Stability of a fluid.
