Glycol Add Calculator and Volume from Change Calculator (2 Excel Spreadsheets)

Glycol Add Calculator:  Many times when working with Hydronic systems containing glycol (antifreeze), the glycol gets diluted with water.  When this occurs, the technician needs to remove a specific amount of mixed fluid and add 100% pure glycol to get the mixture back to the desired concentration.  This calculator determines exactly how much of the diluted mix to remove, and how much pure glycol to add.  The user inputs the freeze point of the current mixture, the estimated volume of the system, and the desired mixture.  The calculator then calculates how much mix to remove and pure glycol to add to achieve the desired concentration.

Volume from Change Calculator:  This Calculator determines the Volume of a Hydronic System knowing the amount of pure glycol added and the beginning and ending freeze points of the mixtures.  This can be very helpful when a technician has added an amount of glycol to the system, but it has not reached the desired concentration level.
