Trane CenTraVac CDHG Duplex Centrifugal Chiller
Duplex CenTraVac for multi-thousand-TR airport plants.
CenTraVac is the world's best-selling large centrifugal chiller family. The CDHG duplex model pairs two three-stage compressors on one evaporator/condenser shell, hitting capacities up to 14 MW (~4,000 TR) per machine with hermetic, direct-drive construction. At Gulf airports, CDHG units anchor central chilled-water plants delivering 4,000 – 10,000 TR trains, often with R-514A (GWP 2) or R-1233zd(E) refrigerants.
