For large chiller plants, the Duplex chiller provides the same features you've come to expect from Trane centrifugal chillers: multiple stages, adaptive feedforward controls, direct-drive compressors, environmentally balanced refrigerant, and factory performance testing. The Duplex chiller is very quiet and has very low water pressure drops, thanks to series-counterflow with single pass evaporators and condensers. Standard parts and proven efficiencies make the Duplex unsurpassed in large cooling applications.
