DOWTHERM™ J Heat Transfer Fluid
DOWTHERM™ J is an alkylated aromatic heat transfer fluid with a broad operating temperature range of −110°F to 600°F (−80°C to 315°C).
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.
