Cleaner running, longer lasting thermal fluids

Most fluids transfer heat and cool with a reasonable degree of efficiency. What really makes the difference though is how long a heat transfer fluid lasts and how clean it keeps your system. Backed by decades of research and hands-on experience, Duratherm’s development team continues to work hard to advance our industry-leading, thermal fluid technologies.

The difference

We have selected Duratherm as they are a global leader in the thermal fluid industry with a reputation built on providing outstanding customer service and technical support. Our dedicated team of professionals have extensive experience working with both end-users and our OE partners. We’re always available to help you meet your needs across a wide variety of applications.

  • Comprehensive engineering and technical support
  • Complete engineering data available for our full line of thermal fluids
  • Lifetime complimentary in-house fluid analysis
  • Custom thermal fluids engineered to your exact needs
  • OEM product development assistance and private label

Just about any fluid will transfer heat with some degree of efficiency; it’s how long it lasts and how clean it keeps your system while it’s running that makes the difference.

Duratherms range of various highly stable, naturally resilient, base fluids  continues with a proprietary blend of additives. These aren’t just off-the-shelf generic additives; their package is finely tuned and formulated specifically for high temperature thermal fluid use and the most demanding of applications.
While some might say the use of additives is not necessary, click on the link below and decide for yourself if your system needs the extra protection of Duratherm.

Collection of  thermal fluid samples are not collected in a representative method, artificially high flash point values will be returned. This results in the end user perceiving a lower risk from flash points than is actually correct.

This has obvious insurance, health and safety and, with the effect of the new (EUROPE) regulations, important legislative implications.

The Legal Requirements for Thermal Fluid Systems and Representative Fluid Analysis DSEAR (Dangerous Substances & Explosive Atmospheres Regulations 2002).

Health and safety legislation, requiring that employers provide a safe working environment, has been around for a long
time. In the past, just how that was to be achieved was largely up to the employer.

Now, where flammable materials that could create an explosive atmosphere are being handled, DSEAR (ATEX/CAD in
Europe) set out a mechanism for minimising the risks. Employers have a legal obligation not only to abide by this but to
prepare and maintain documentary evidence.

Oxidative Degradation (Most Common)

Oxidation occurs when heated fluid is exposed to air. It is one of the most common forms of degradation and can lead to the formation of sludge. While various heat transfer fluid chemistries oxidize at different temperatures, Duratherm fluids will normally start to oxidize
above 93°C. It is also generally accepted that for every 15C° increase in temperature above 93°C, the rate of oxidation doubles.
