![]() Diluting heat transfer fluids to less than 30% of glycol may reduce inhibitor concentrations to levels too low to provide adequate corrosion protection and dilutions of less than 25% may be at risk of bacterial contamination. Glycol acts as a natural bactericide. The maximum recommended concentration of glycol is 60% for efficient heat transfer since relative heat transfer efficiency may be sacrificed. To read more about concentration and burst or freeze points check out our post "Difference between burst protection and freeze protection".
