Glycol is a crucial fluid in HVAC, automotive, oil & gas, food production, and pharmaceuticals, prized for its ability to transfer heat, resist freezing, and maintain system performance under extreme conditions.
The two main types — ethylene glycol and propylene glycol — are essential for applications ranging from antifreeze systems and industrial cooling to natural gas dehydration and food-safe thermal transfer.
Glycol is an organic compound belonging to the alcohol family. Its two most common forms, ethylene glycol and propylene glycol, are celebrated for their versatility. These compounds are indispensable in sectors requiring stable thermal management, low toxicity options, and corrosion resistance. You can learn more about its thermal and chemical properties in Red River’s guide to glycol material properties and uses in industry.
Ethylene glycol is known for superior heat transfer properties, making it ideal in antifreeze and industrial cooling systems.
Propylene glycol, while slightly less efficient in heat transfer, is non-toxic and widely used in food, beverage, cosmetics, and pharmaceuticals.
In HVAC systems, glycol acts as an efficient heat transfer fluid, ensuring stable temperature control in both heating and cooling systems. Whether in industrial complexes or commercial buildings, glycol-based solutions improve energy efficiency, system reliability, and corrosion protection.
For insight into how glycol expansion tanks regulate system pressure and protect components, see Red River’s expert guide on glycol expansion tanks.
In natural gas processing, glycol removes water vapor from gas streams, preventing hydrate formation that can block pipelines. This ensures uninterrupted flow and long-term pipeline integrity.
Thanks to its high boiling point and low freezing point, glycol is ideal for industrial thermal management — from refrigeration units to renewable energy systems like solar thermal and geothermal heating.

Glycol prevents freezing in automotive, aviation, and industrial cooling systems, protecting engines and equipment in extreme cold. It also includes corrosion inhibitors for longer equipment life.
Glycol dehydration units are vital in the natural gas industry. In particular, these units utilize glycol to absorb water from natural gas streams, thereby preventing hydrate formation and ensuring the smooth flow of gas through pipelines. Consequently, this process is crucial for maintaining the operational efficiency and safety of natural gas production and transport.
In the oil and gas sector, glycol reduces corrosion, prevents hydrate formation, and enhances drilling and production efficiency — cutting downtime and extending equipment lifespan.
Ethylene glycol offers better heat transfer but is toxic; propylene glycol is safer but slightly less efficient.
Yes, it is recognized as safe for food and pharmaceutical use by regulatory agencies, provided it is used within recommended limits.
It forms a protective film and includes corrosion inhibitors to reduce oxidation.
Yes, glycol can be used in renewable energy systems, particularly in solar thermal and geothermal heating applications. In these systems, glycol acts as a heat transfer fluid, effectively capturing and transferring heat from the energy source to the desired location.
The environmental impact of glycol depends on the type used and how it is managed. Ethylene glycol is toxic and can harm wildlife and ecosystems if not properly disposed of. Propylene glycol is considered less harmful and more environmentally friendly. Regardless, both types should be handled and disposed of according to environmental regulations to minimize impact.
It depends on application and lowest ambient temperature; typically 30–50% for HVAC and antifreeze.
