Overview
DOWTHERM™ T is a synthetic heat transfer fluid based on a mixture of alkyl benzenes (C14-C30) for use in nonpressurized liquid systems at −10°C to 288°C (14°F to 550°F) and a max bulk temperature of 315°C (600°F). DOWTHERM™ T fluid exhibits favorable physical properties and low vapor pressure at the maximum use temperature due to its high flash and fire points between 188°C and 210°C. At the same time, it provides good low-temperature properties and exceptional stability at high-temperature operations.
DOWTHERM™ T provides incredibly long fluid life and excellent heat transfer across a very broad range of applications, including oil and gas processing, plastic processing, chemical processing, solar energy, heat recovery, industrial boilers, and mechanical heating.

Features & Benefits
Synthetic organic fluid alternative to hot oils
Optimal economic bulk operating temperature of 288°C
No steam tracing is required to −10°C
Liquid phase heat transfer operation only
Does not require a pressurized expansion tank
Lower operating costs due to lower makeup rates
Faster start-up time
Reduced capital costs due to lower surface area in heat exchanges and lower-temperature pumpability compared to some mineral oil
Reduced heat exchanger fouling during operation due to lower heater film temperatures, lower heat stress on heat transfer fluid, and reduced fluid degradation
Problems Solved
Ineffective thermal fluid start-up at low temperatures
Poor heat transfer fluid stability or chemical incompatibility
Applications
DOWTHERM™ T is an ideal heat transfer fluid of choice in a wide range of thermal transfer applications, including but not limited to the following:
Pharmaceutical manufacturing
Oil and gas refineries
Plastic processing, including copolymer and fibers
Chemical processing, including distillation and synthesis
Solar energy systems
Heat recovery Industrial boilers
Jacketed reaction vessels
Environmental test chambers
Mechanical heating, including calender rolling and parts manufacturing
