A Chiller Unit is an packaged equipment that removes heat from a liquid via a vapor-compression or absorption refrigeration cycle. This liquid can then be circulated through a heat exchanger to cool equipment, or another process stream (such as air or process water). As a necessary by product, refrigeration creates waste heat that must be exhausted to ambiance, or for greater efficiency, recovered for heating purposes. A Portable Chiller is a small type chiller for used on remote or group of drinking fountains.
