5 Tips to Find a Fluid

Did you know there are many options to consider when selecting thermal fluids?

  1. Temperature is Everything – match your bulk temperature but also consider film temperature, heater type
  2. Controlling Oxidation – high temperature air exposure can destroy the wrong fluid quickly
  3. Maximizing Fluid Life – short-term or long-term use – invest wisely
  4. Availability is Critical – thermal fluids are often critical to production – how long can you wait for your thermal fluid to ship?
  5. Reliable Service & Support – thermal fluids are maintenance-intensive, but can your vendor help you if there are problem

Heat Transfer Fluid – Thermal Fluids

Duratherm offers a wide range of thermal fluids (heat transfer fluid) for just about every application and uses anywhere from -84ºC (-120ºF) right up to 338ºC (640ºF). Most are non-toxic and non-hazardous, some even food-grade, but all are highly efficient, clean-running, and long-lasting.

Confused? We Can Help

Choosing a heat transfer fluid (also called thermal fluid or thermal oil) can be difficult decision. What makes one better than the other? Why do some last longer? How do I know which one is best for my application?

Truth is a lot of heat transfer fluids look alike and If specified properly, they all transfer heat efficiently — the difference is ours just tend to last longer. And while most of the time heat transfer fluids run trouble-free, you want to also choose a company who has the expertise and responsive support to help you when they don’t. All we do is heat transfer fluids and we spend every day helping the people that use them or need help choosing them.

Help is just a phone call or email away – our technical support team – not sales people – are readily available to learn more about your needs and application
