100% Propylene Glycol – USP certified – Food Grade
USP (United States Pharmacopeia) is the official standard setting authority for medicines, supplements and health care products in the United States. Any glycol carrying the USP Grade provides assurance the product is definitely approved for Food Applications and is of the highest quality making it perfect for brewing and use around food or food related products.
Our glycol chillers will operate with 33 % – 100 % glycol mix ratio. We recommend aiming for a 50 % mix ratio. While a 33 % mixture will work, any errors while mixing a 33 % solution can leave you with a mix that still freezes at your desired operating temperature. A 50 % mix ratio is what we use when testing our glycol chillers down to -14 degrees Fahrenheit without any freeze issues.
