What Is Inhibited Glycol?
Inhibited glycol is a heat transfer fluid designed for applications where environmental conditions require a low freezing point while retaining the good heat transfer efficiency of water. Glycols lower the freeze point of water preventing pipe burst. Inhibited glycols have corrosion inhibitors and are formulated specifically for a given application.
What Is Inhibited Glycol Used For?
Automotive antifreeze is an example as is aircraft deicer but the two have much different inhibitor packages. Additional applications include HVAC systems, flooded fire suppression systems, secondary cooling of fluid milk and other foods, and oil & gas applications such as line heaters, separators, and stationary engines.
Inhibited glycols are available as a dilutable concentrate or in a pre-diluted, ready-to-use form.
Inhibited Glycol vs. Uninhibited Glycol
Brenntag offers technical grade glycols and food-grade glycols with or without corrosion inhibitors. Inhibited glycols are largely used for heat transfer applications. Corrosion inhibitor packages are application specific and cover a broad range of applications. Corrosion inhibitors are used to protect the investment in expensive equipment that would suffer damage and eventual failure if the glycol were left uninhibited. Inhibited glycols are most often dyed to distinguish them from other products. Uninhibited glycols are largely used as chemical intermediates or as solvents.
Inhibited propylene glycol is a relatively safe chemical to handle, and it doesn’t require any special protection to use. Some of its features are:
- A boiling point of 370 degrees Fahrenheit.
- A flash point of 215 degree Fahrenheit.
- Complete solubility in water.
- Colorless and odorless.
Since there is no special equipment required to use inhibited propylene glycol, you can easily wash it off your skin. However, you should avoid getting it into your eyes. If that happens, flush your eyes with water for at least five minutes. If you ingest a large amount, induce vomiting to remove it from your system. Make sure to always use it in a well-ventilated area.
Ethylene glycol requires a bit more care in handling than propylene glycol. Some features of ethylene glycol are:
- A boiling point of 387 degrees Fahrenheit.
- A flash point of 241 degrees Fahrenheit.
- Complete solubility in water.
- Colorless and practically odorless.
Inhibited ethylene glycol can cause slight irritation on contact with your skin. Rubber gloves and protective clothing should always be worn when handling Inhibited Ethylene Glycol. Avoid getting it into your eyes. If this happens, flush your eyes with water immediately. Additionally, if you ingest the substance, you need to induce vomiting immediately. Three ounces is estimated to be a lethal dose when ingested. Ethylene glycol has a low vapor pressure, so inhaling too much is unlikely.
