Most fluids will transfer heat with some degree of efficiency but it's how long it lasts and how clean it keeps your system that really makes the difference.

Duratherm 600 - thermal fluid rated to 600°F it contains the industries most aggressive blend of additives for long, trouble free operation in a variety of applications.

Duratherm 630 - rated to 630°F it has the highest rated bulk temperature of petroleum based thermal fluids. Duratherm 630 is engineered for applications requiring high temperature stability (630°F) and offers one of the only environmentally friendly alternatives to aromatic fluids at a fraction of the cost.

Duratherm 450 - thermal fluid specifically engineered for applications requiring process heating and cooling efficiently between 30°F and 450°F.

Duratherm FG - thermal oil rated to 620°F it's engineered and manufactured to comply with the demands of food grade applications. NSF registered, meets USDA requirements for incidental food contact (H1) and meets the requirements of 21CFR1783570.

Duratherm G - Glycol fluids such as Ucon 500(TM) have been used for years but have, until now offered very little protection from negative elements such as oxidation.

Duratherm S - a silicone based heat transfer fluid that is ideally suited for high oxidation or completely exposed systems up to 650°F.

Duratherm LT - heat transfer fluid engineered for applications requiring process temperatures ranging from -30°F to 600°F.

Duratherm Lite - a heat transfer fluid with the same physical properties as Duratherm 600 but formulated with a lighter dose of additives.

DuraFlush - a light petroleum based fluid compatible with most oils. DuraFlush is used to flush systems prior to filling with a heat transfer fluid.

Since 1977 our goal has been to strive for constant innovation and improvement. Through years of ongoing R&D we are proud to offer the industries most expansive line of Heat Transfer Fluids (also called Hot Oils, Thermic Oils or Thermal Fluids) as well as System Cleaners.

When comparing physical properties there are obvious considerations that must be taken, such as temperatures, safety, etc but what isn't always on a physical specification sheet is what's working in the background to keep the fluid running longer and cleaner.

Having problems with your current fluid but not sure what criteria would improve your situation? First time selecting a heat transfer fluid and not sure which type of fluid to go with?

Not sure exactly what criteria you should be considering for your specific system or needs? We've provided an honest, and unbiased, overview of the fluid selection process and the criteria that should be considered when choosing a fluid.

Access to some of the more advanced technical resources we provide.

We've compiled technical specifications of over 30 commonly used Heat Transfer Fluids. This utility allows you to easily compare the properties of our products with those of our competitors or even compare competitor products against each other.

A few useful utilities we've found that make system design, engineering or simply unit conversions quick and easy.

If you've found your way to our site you're likely seeking or researching heat transfer fluids. Most of our customers are new to heat transfer fluids, fluids that can be a bit of a mystery and a little confusing to someone outside the industry.

Are you new to heat transfer fluids and not quite sure what they are all about or what some of the industry lingo means?

For over 25 years we have been servicing the heat transfer fluid industry with quality, effective and innovative products ranging from heat transfer fluid and related products, thermal oils, thermic fluids as well as specialized lubricants throughout the world.

Driven by our customers demand for excellence, we engineer all our products to simply last longer and run cleaner (see how).

Today's fast pasted production schedules don't always allow for timely oil changes and preventative maintenance. This situation over time can result in harmful deposits being created within your system, ultimately leading to equipment failure.

DuraClean - a long life, preventative maintenance and light duty system cleaner, in addition to functioning as a long term heat transfer fluid.

DuraClean Concentrate - is added to a system a few weeks prior to an oil change. Engineered as a maintenance aid it reduces the manual labor hours spent cleaning a system during maintenance programs such as PM's and teardowns.

Carb-off - Recommended by major equipment OEM’s, the fast acting formulation makes it perfect for stripping fouled heat transfer systems of oxidized and thermally degraded oil deposits.

U-Clean - is another first for the industry. Finally a cleaning fluid compatible with Polyalkylene Glycol fluids such as Ucon 500® which is safe and effective to use at temperatures up to 500°F.

Duraclean LSC - large system cleaner added as a concentrate to larger systems, it allows continued production up to 600°F.

Our experience in developing world class heat transfer products naturally lead us to develop equally effective industrial lubricants
