Since this column will appear in our January issue, I can finally tell you about a project that has been in the works for quite a while: our new eBook on thermal fluid heating for industrial processes. (If you want to skip ahead and just get to reading, you can download the eBook for free at

“An End User’s Guide to Heat Transfer Fluids and Thermal Fluid Systems” is written as a practical guide to specifying a thermal fluid heating system for industrial process applications. It covers every stage of specifying a thermal fluid heating solution, including:

Choosing a heat transfer fluid.

  • Fluid testing.
  • Fired thermal fluid heaters.
  • Electric thermal fluid heaters.
  • Sealed and sealless thermal fluid pumps.
  • Pumps for 650 to 750°F service.
  • The expansion tank.
  • Piping, valves and insulation.

Of course, this eBook would not be possible without the efforts of its author, Jay Hudson. In addition to Jay’s 40 years of experience in myriad roles for thermal fluid heating — plant process development engineer, plant project engineer, process engineer in engineering firms, and project manager in engineering firms — Jay is a principal member of the technical committee for NFPA87, the standard for fluid heaters. That experience, coupled with his experience as thermal fluid system consultant offering insights on design, installation, startup and troubleshooting, proved invaluable in developing our eBook.

I also want extend my personal appreciation to the eBook sponsors for their support of this project. It would not have been possible without their sponsorship.

As it happens, our eBook on thermal fluid heating is not our only resource you can tap. On page 18, we have the latest edition of our Equipment Overview on Heat Transfer Fluids. You can use our overview to do the preliminary work of comparing heat transfer fluids for your next thermal fluid heating project. The Equipment Overview includes key fluid data such as maximum bulk and film temperatures, autoignition temperature and fluid density.
