Overview

Dow glycol-based fluids include inhibited ethylene glycol (EG) and propylene glycol (PG)-based fluids. The inhibitors in Dow glycol-fluids are specially formulated to protect system components against corrosion and scaling that can increase maintenance and operating expense, reduce system efficiency and even lead to system failure.

In most water-based heat transfer applications, EG-based fluids offer excellent heat transfer efficiency and somewhat lower operating temperature ranges due to the lower viscosity of EG solutions compared to equal concentrations of PG. PG fluids are most commonly used in applications requiring low acute oral toxicity or where incidental contact with drinking water is possible. In some areas, use of PG fluids is required by local regulation. Glycol based Fluids properties and performance of glycol fluids under your specific system conditions. See Burst Protection and Freeze Protection for guidance in setting the proper glycol concentration.
