Dosing with Glycol

Dosing with Glycol


Glycol is a chemical often used in cooling systems as an antifreeze, as it adjusts the temperature range of a system. During winter seasons especially, it’s important to protect your water systems, by regularly checking and servicing them, as well as working with a professional to understand if they need to be treated with glycol in order to lower the system freezing point.

Dosing with Glycol

The percent of glycol added, determines what the new freezing point will be. A lower freezing point means process fluid can be kept at colder temperatures. Glycol doesn’t dissipate as quickly as organic compounds like inhibitors, but it’s crucial that you have the correct levels and keep it topped up. With the appropriate dose, you can avoid frozen pipes, split valves, and an underperforming system during winter and any down-time.

Adding Glycol

We can also help you choose the right type of glycol for your system. While mono ethylene is most cost-effective, Comfort Coolflow includes corrosion inhibitors and biocides for extra peace of mind. The right solution for you will depend on things like:

  • Whether you have trace heating (and its condition)

  • Compatibility with previously-used chemicals in your system

  • Your percentage of external pipework

We’ll guide you through your options, and can then attend on-site regularly to check glycol levels.
