Dowtherm J

DOWTHERM J, high-performance heat transfer fluid, made from isomers of an alkylated aromatic compound, designed for low-temperature applications in pressurized liquid-phase systems. Operates efficiently from -80°C (-110°F) to 315°C (600°F), easy to pump at low temperatures.

Safe for use in both liquid and vapor-phase systems, with vapor-phase use between 180°C (356°F) and 315°C (600°F)

Key Features:

• Low-Temperature Pumpability: Efficient operation and flow in extremely low, subzero environments down to -80°C (-110°F).
• Excellent Thermal Stability: Provides superior protection against accidental overheating.
• Liquid and Vapor phase: With a temperature range from -80°C to 315°C for liquid phase and 180°C to 315°C for vapor phase.

Intended Applications:

DOWTHERM J is widely used in industries requiring precise temperature control for processes such as:

• Pharmaceutical manufacturing: for precise heating in chemical reactors.
• Plastics and polymer production: in processes like polymerization and extrusion.
• Oil and Gas: is used to maintain controlled temperatures in processes such as refining, distillation, and thermal cracking. To find out if Dowfrost, Dowtherm, or Syltherm is most suitable for your oil and gas application see our guide sheet here
• Chemical Processing: employed for precise temperature regulation in reactors, distillation columns, and condensers. Ability to operate at high temperatures makes it ideal for processes like polymerization, alkylation, and synthesis reactions
• Food processing: where indirect heating is critical for maintaining product integrity.
• Concentrated solar power plants: for transferring heat to generate electricity.
