Characteristics of Heat Transfer Fluids
A variety of chemical compounds can be used to formulate heat transfer fluids which are used to prevent water from freezing when the temperature of the fluid reaches below 0°C (32°F). The most common are: ethanol (ethyl alcohol) methanol (methyl alcohol) ethylene glycol (1,2-ethanediol) propylene glycol (1,2-propanediol) bio-based propylene glycol (1,3-propanediol) The basic properties of these freeze…
