Overview
DOWTHERM™ Q is a high-performance heat transfer fluid for liquid phase systems between −35°C and 330°C (−30°F to 625°F). DOWTHERM™ Q exhibits significantly greater low-temperature pumpability in comparison to hot oils.
DOWTHERM™ Q heat transfer fluid is a suitable replacement for hot oils in a variety of high-temperature systems. DOWTHERM™ Q is also noncorrosive to common alloys and metals used in thermal transfer systems.
