Propylene Glycol is an antifreeze coolant for use in long draw dispense systems to keep your lines cool from the kegs to the faucet. This concentrated glycol mixes with water to create the solution for your glycol chiller. The solution is 2 1/2 parts water for every 1 part glycol. This one gallon container will create 3 1/2 gallons of solution.
For best perfomance, it is always reccomended to flush and refill glycols baths annually.
