Overview
DOWTHERM™ J is an alkylated aromatic fluid engineered for heat transfer applications. It offers remarkable low-temperature pumpability and thermal stability, which enhance protection against accidental overheating.
DOWTHERM™ J heat transfer fluid brings exceptional performance for liquid-phase pressurized systems and, in some cases, can eliminate the need for steam tracing.
DOWTHERM™ J fluid is an ideal choice for single-fluid heating and cooling applications like batch processing. DOWTHERM™ J is noncorrosive toward metals and alloys commonly used in system design.
