The Benefits of Glycol And Why You Need It.

Discover the numerous advantages of glycol in heat transfer applications. From safeguarding against freezing and corrosion to heightened performance prolonged equipment life. For a more in-depth explanation, check out our side-by-side analysis of propylene and ethylene glycol.

Freeze Protection

Glycol-based heat transfer fluids have a lower freezing point compared to water. This property makes them suitable for use in cold climates or in systems that may be exposed to sub-freezing temperatures. By adding glycol to the water, you can prevent the fluid from freezing and damaging the system.

Burst Protection

In addition to preventing freezing, glycol also provides burst protection. When water freezes, it expands, which can lead to pipes, valves, and other components bursting. Glycol's antifreeze properties reduce the risk of such damage.

Corrosion Inhibition

Dow Glycol-based heat transfer fluids contain corrosion inhibitors that help protect the system and its components from rust and corrosion. This is crucial for the longevity and reliability of the equipment.
