30 Mechanical Minutes: Episode 20 "Glycol and Hydronics"

In this edition of 30 Mechanical Minutes we are joined once again by hydronics industry expert John Siegenthaler to talk about the effects of putting antifreeze in your hydronics circuits. Used in a variety of applications, like snow and ice melt and in monoblock air-to-water heat pumps, inhibited propylene glycol is the most common fluid used for antifreeze requirements, and John shares some of the characteristic of adding glycol to water.
