Below is a list of Chillers manufacturers from Austin, Texas. Chillers are machines that remove heat from liquids and release it into the atmosphere by means of a refrigeration cycle. The chilled liquid, also known as a coolant, is then directed to a heat exchanger to cool process equipment, air or another liquid. Chiller systems range vastly in size and design and may be fabricated as small, localized or portable chiller units for small applications or as large central chillers designed to provide cooling for entire facilities.
