Heat Transfer Fluid Touts Longer Life

Paratherm Corp. recently introduced the new Paratherm HR Heat Transfer Fluid, which is said to expand the high temperature range for processing applications. The product 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. With proper maintenance (an annual fluid analysis) the fluid has a lifespan of five to eight years and targets industry applications including gas, plastic and chemical processing, waste-oil recovery and biodiesel production.

Paratherm HR also has a lower start-up temperature of 13°F (-11°C). Centrifugal pumps are generally specified based on the fluid viscosity at the desired operating temperature. Capacity falls off significantly at viscosity values above the 300 cPs line. So the actual minimum start-up temperature is where the viscosity curve crosses the 300 cPs line.
