GLYCOL SYSTEMS
Glycol Concentration
The system must be filled with water and the appropriate amount of glycol (either ethylene or propylene)
inhibitors to protect against winter freeze-up and premature coil corrosion. To achieve the approximate
glycol concentration, it is necessary to know the total system volume. This consists of the sum of the
fluid cooler volume, the evaporator unit volume and the volume of the inter-connecting piping.
The following tables can be used for arriving at an approximate system volume. After installation, the
glycol percentage should be checked. The glycol percentage should also be checked at regular
intervals to ensure freeze protection.
