Propylene glycol vs distilled water
WebbEthylene glycol and propylene glycol have higher vapor points and therefore can absorb heat at higher temperatures without boiling. Yet even with its lower vapor point, water still carries more heat per unit. Don’t forget that the coolant is just one part of the total cooling-system “team.”. You can raise water’s effective vapor point ...
