Inside a typical brewery’s chilled cooling loop, you will almost always find a percentage of propylene glycol, also called propane-1,2-diol. Typically a percentage of anywhere from 40% to 50% is ran for adequate freeze protection. Propylene glycol’s chemical formula is C3H8O2, which makes it an organic compound. It has a pink color, and was developed as a more food-grade glycol compared to its more environmentally hazardous counterpart, ethylene glycol. Ethylene glycol is not used in breweries because it is dangerous to humans if accidentally consumed. Whaley designs and builds its chiller systems to ensure that no food grade propylene glycol touches potable water, or any other potable food substance. It is a good idea to keep a glycol concentration detector on hand at a brewery in order to test your glycol concentration regularly to ensure you have the optimum freeze protection built up in your system at all times.
