The higher heat capacity and thermal conductivity of glycol-based heat transfer fluids makes them far more efficient in terms of heat transfer than non-aqueous alternatives. This has the effect of reducing overall energy consumption, thereby lowering both carbon dioxide emissions and long-term financial costs. In addition, the high biodegradability and low bioaccumulation potential of aqueous-based heat transfer fluids give them a superior environmental profile to non-aqueous-based equivalents.
It is well understood that glycol/water mixtures (commonly referred to as antifreeze) are inherently corrosive and the use of simple commodity chemicals, like glycols, as heat transfer fluids can lead to significant issues, such as corrosion and fouling of processing equipment, resulting in increased downtime and, in some cases, expensive repairs and replacements.
