Antifreeze in heat transfer fluids

Antifreeze Chemicals & Function

For refrigerated systems that are designed to operate at sub-zero temperatures and systems that are periodically subjected to sub-zero ambient temperatures, then the heat transfer fluid must have an antifreeze capability.

There are a large number of chemicals that exhibit sub-zero antifreeze characteristics, but only a handful that are commonly used in the process cooling, refrigeration, air conditioning and renewable energy sectors.
