Overview
DOWTHERM™ A is a synthetic organic thermal fluid based on a eutectic mixture of two highly stable compounds: biphenyl (C12H10) and diphenyl oxide (C12H10O). DOWTHERM™ A can be used in both liquid- and vapor-phase systems and is suitable for indirect heat transfer applications.
DOWTHERM™ A heat transfer fluid provides excellent thermal transfer in applications between 15°C and 400°C (60°F and 750°F).
