DOWTHERM™ J

An Alkylated Aromatic Heat Transfer Fluid with Broad Operating Temperature Range of -110°F to 600°F (-80°C to 315°C).
Product Overview

DOWTHERM™ J offers remarkable low-temperature pumpability and thermal stability for 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 is an ideal choice for single fluid heating and cooling applications like batch processing. DOWTHERM™ J is noncorrosive towards metals and alloys commonly used in system design.
