What To Expect From Heat Transfer Oil Testing

When your heat transfer fluid sample finally makes it to the laboratory, manufacturers like Relatherm Heat Transfer Fluids often test for physical and chemical properties such as Flash Point, Total Acid Number (TAN), Kinematic Viscosity, Auto-ignition Temperature and moisture content. More advanced tests can also include simulated distillation by Gas Chromatography and Fourier Transform Infrared (FTIR) Spectroscopy.

You should expect a detailed analytical report specifying the values of these parameters. These parameters will be typically shown on a line graph if you ordered similar tests from the same supplier in the past.  Thresholds will typically be included in the report so you can benchmark the values. This helps you to make an informed decision on what to do with your heat transfer fluid. Our Thermal Fluid Engineers make a definitive assessment indicating if your heat transfer fluid is within acceptable parameters. We also let you know if your fluid is oxidized, cracked or contaminated. You can read about thermal fluid degradation causes here. Feel free to contact Relatherm Heat Transfer Fluid with any questions you have on heat transfer fluids or the sampling, testing and analysis of used thermal fluids.
