Duplex™ CenTraVac™ Chiller

1,500 to 4,000 Tons

Designed for large capacity applications such as campuses, district cooling plants and industrial processes, the Trane Duplex chiller builds on the highly successful EarthWise™ CenTraVac chiller by using the same design principles that have been proven for more than 75 years.

The Duplex chiller consists of two separate compressors with independent refrigerant circuits in a series counterflow arrangement which reduces the chiller power consumption by reducing the lift on the chiller. This design philosophy also delivers a degree of redundancy and results in a reduced starting inrush current compared to that of a single compressor chiller.

Benefits of a Duplex Chiller:

  •  Industry’s highest efficiencies in large tonnage applications

  • Superior part load efficiencies using Adaptive Frequency™ drives to leverage low lift conditions

  • Reduced footprint with unit mounted starter and Adaptive Frequency drive options

  •  Low pumping costs from single pass design

  • Chiller performance verification through AHRI-certified factory testing

  • Additional system energy saving options including thermal storage and partial heat recovery
