Too often, functional fluids are used as heat transfer fluids - not an effective application.
Functional fluids are used in industrial applications as lubricants, hydraulic and transmission fluids, metal-working fluids and dielectric fluids, to name a few of their many purposes. In those uses, they are effective. Yet too often, these fluids are used as heat transfer fluids - not an effective application.
In a white paper from Paratherm Corp., West Conshohocken, Pa., the uses for functional fluids and why they are not the best choice for heat transfer applications are explained. As the paper notes, "Hydraulic fluids and lubricating oils are specific examples of fluids formulated for particular properties; these are also the categories of petroleum-based liquids most often misapplied as heat transfer fluids."
