The GP Series is available as water-cooled, air-cooled or remote air-cooled units. Air-cooled models, both local and remote, utilize microchannel air-cooled condenser coils. The all-aluminum coil design is constructed of multiple parallel-flow aluminum tubes that are then brazed to highly efficient aluminum fins. Water-cooled models can be combined with cooling towers and other existing process cooling water supplies. The variance in condenser water temperatures between air- and water-cooled models equates to a higher operating capacity for water-cooled models of the same size. Packaged chillers are designed to house all of the components necessary for the cooling requirements, with integrated pumps and tanks.
