FLUIDFILE™ is designed to work the way you do, allowing intuitive access to the information you require to make informed fluid selection decisions. Our global family of DOWTHERM™ and DOWFROST™ glycol-based fluids and DOWTHERM™ and SYLTHERM* synthetic fluids is represented in FLUIDFILE, so you can thoroughly explore all of your options in one place. To match the right Dow fluid to your system requirements, simply choose Calculate Fluid Properties to obtain glycol or synthetic fluid properties under your specific system conditions, for one fluid or to compare properties of multiple fluids.

You won’t need prior experience with Dow Heat Transfer Fluids to obtain the information you need to select the right fluid. To assist in your fluid decision-making, About Dow Fluids provides an overview of our fluids line, guidance in choosing a fluid chemistry including application information, plus profiles of the individual fluids.
