Below is a list of Portable Chillers manufacturers from Waltham, Massachusetts. Portable chillers are relatively small, movable, single pump machines that remove heat from a liquid through a cycle of compression, condensation, and evaporation. The chilled liquid is usually then piped as a coolant to a heat exchanger in order to cool a piece of equipment, a manufacturing process, or a stream of air. These self-contained chillers are useful in small and/or dedicated applications and have the ability to cool one or two machines at a time.
