In industrial and mobile equipment heating solutions, most systems generally use water or glycol mixtures for fluid. Although water is the most efficient liquid for heat transfer, it freezes – for this reason, many industries prefer glycol. If you’re trying to achieve better temperature control, maintain a certain temperature, or protect pipes and equipment from freezing, glycol is a suitable fluid for all of the above and more.
What is glycol?
Glycol is an organic, odourless, colourless, and flammable organic compound that is categorized into two separate types: ethylene glycol (commonly used as antifreeze) and propylene glycol (a non-toxic preservative and moisture-retaining agent that’s widely used in consumables).
Glycol is used to heat or cool a building and help equipment work more efficiently. Much like fuel and fluid heat exchangers, glycol to air heat exchangers passes one fluid to another without mixing together. Glycol, a chemical compound in the alcohol family, is safe to use in frigid temperatures without freezing.
HVAC applications that commonly use glycol include:
- Snow and ice melting systems
- Solar water heating systems
- Ground source heat pumps
- Chilled water-cooling systems
- Hydronic systems
Why use glycol as a heating solution?
Some of the benefits of using glycol to air heat exchangers include the following:
- They have a higher boiling point than water, making them ideal for high-temperature applications.
- It can withstand colder temperatures, making glycol an excellent option for freeze protection.
- More cost-efficient than water as the greater temperature range and the lower freezing point does not require the heater to run as often.
- Unlike water, glycol does not freeze but instead turns into a slush, allowing the fluid to continue to flow.
- Glycol is a less viscous fluid that provides rapid heat transfer.
- Efficient heating reduces operational costs and energy consumption.
- A stable, high temperature prevents chemical degradation and, thus, prevents system corrosion.
- Industrial-grade glycol is formulated with anti-corrosive additives that eliminate corrosion and reduces maintenance costs.
