Trane Duplex Centrifugal Chillers
From Whaley Products, Incorporated
Model CDHF/60 Hz 1,500 to 3,950 Tons
Model CDHG/50 Hz 1,200 to 2,500 Tons
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.
CH530 Control Panel Adaptive™ Control keeps chiller online when other chillers shut down.
Provides the benefits of series chillers without the extra engineering, piping and control requirements. Built-in series optimization simplifies operation and chiller plant sequencing.
Direct-drive compressors with low-pressure refrigerant rotate slowly for high reliability and efficiency (no gears), low sound, and very low direct and indirect greenhouse gas emissions.
Multiple stages (4-6) yield wide operation envelope and excellent part load stability and efficiency.
Series-counterflow arrangement with single-pass evaporators and condensers creates wide delta-T and high efficiency without increasing pump energy.
Factory assembled in ISO 9001-certified quality manufacturing plant
Lowest sound levels in the industry
Trane performance testing capabilities are the best in the industry, so there are no startup surprises or underperforming chillers.
Two independent refrigerant circuits mean the compressors do not compete for refrigerant, creating more capacity at a higher efficiency.
