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. Chiller performance can be verified on an AHRI-approved test stand.

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

A sustainable product with the papers to prove it… The Trane CenTraVac commercial chiller is the first (and only) commercial chiller in the world to earn Environmental Product Declaration (EPD) registration based on a third-party life cycle assessment.
