Common Applications of Inhibited Propylene Glycol

Inhibited propylene glycol is an organic double alcohol widely utilized for controlling several industrial functions like secondary cooling and heating applications, anti-freeze and bursting protection for pipes during colder months, various defrosting, de-icing, and dehumidifying purposes.

Inhibited propylene glycol in IUPAC nomenclature is propane-1,2-diol. Its single atom has three carbon atoms, eight hydrogen atoms, and two oxygen atoms represented by the formula C3H8O2. Pure propylene glycol is synthesized through the hydration of propylene oxide. Its other industrial
applications include foods, toiletries, and cosmetic products to serve as humectant and preservative.

Other Usages:

•Chillers
•Cold room dehumidifiers
•Heat recovery
•Boilers
•Refrigeration coil defrosting
•Sidewalk snow-melt systems
•Refrigeration warehouse floor heating
•Liquid food chillers
•Outdoor wood boilers
•Freeze/burst/corrosion protection for HVAC system
•Thermal energy storage (TES) systems
•Air preheating
•Immersion freezing or chilling for solid, wrapped foods
•Ground source heat pumps
•Process heating and chilling
•Moderate temperature batch processing
•Conveyor roller defrosting
•Fermentation and indirect food cooling
•Solar heating
•Ice skating rinks
•Beverage processing for wines and beers
•Radiant floor heating
•Hydronic heating systems

Different glycol fluids are used for the same functions because of their similarity in physical characteristics though propylene glycol is one of the safest glycol to use. Its freeze and burst protection is slightly better, though in comparison to other derivatives, it poses minimal environmental contamination or toxicity.
