Get the right fluid

Eastman Therminol® heat transfer fluid (HTF) provides precise temperature control in a variety of applications. From processing oil and gas in the coldest climates to extracting the most heat in a concentrated solar power array, Therminol has provided high performance and stability for more than 60 years. Find the right fluid for your system by browsing these thermal fluid applications.

Hydrocarbon processing

We rely on efficient and economical sources of energy and heat to run our factories, cool our homes, cook our food and transport goods. Therminol has played a significant role in hydrocarbon processing industries and applications — such as petrochemicals, oil and gas processing, and refining —to meet those needs.

Plastics processing

Plastics and polymer production uses manufacturing equipment that requires operational flexibility. Some operations require high heat and precise temperature control. Whether liquid- or vapor-phase operation, Therminol has been extensively used in these critical applications.

Chemical processing

Some chemical applications require very low temperatures, precise temperature control or multistep chemical processes that span various temperature ranges. Chemical and pharmaceutical industries around the world rely on Therminol liquid- and vapor-phase HTF to provide long-term, trouble-free performance in heat transfer systems that are critical to these operations.

Alternative energy

Eastman is committed to creating and working with sustainable technologies. Industries that use Therminol include renewable energy generated by thermal concentrated solar power, waste energy recovery systems (organic Rankine cycle) and biofuels.

Food and beverage processing

Several applications in the food processing industry are well-suited to the use of liquid- and vapor-phase HTF. Vegetable oil deodorizing, food additive manufacturing, food packaging production and food preparation all use HTF to some degree. When operating temperatures prohibit the use of steam or steam is not available, synthetic-based fluids can provide safe and efficient operation in a heat transfer system. A properly designed and maintained system using Therminol will contribute to low-cost operation and efficient production.

Heat processing

Many applications in the heat processing industry are well suited to use HTF to help regulate fluid temperature and provide a controlled environment for chemical reactions. Therminol can be used in medium-density fiberboard (MDF) and desalination applications. Therminol’s thermal stability ensures long life, resistance to fouling and excellent fluid-side heat transfer coefficients for consistent and reliable service.

System maintenance

In properly designed systems, our fluids provide excellent thermal stability within their expected temperature ranges. They also provide years of trouble-free service with minimal downtime. However, less-than-ideal conditions can result in fluid degradation, formation of solids and deposits on heat transfer surfaces. Eastman offers flushing fluid and technical support to ensure your system performs at its best.
