CenTraVac® Water-Cooled Data Center Chillers
Models CDHH & CVHH
Overview
Up to 21MW Cooling Capacity in a Single Package
Trane CenTraVac® CDHH and CVHH chillers are engineered to meet the demanding needs of hyperscale and colocation data centers with exceptional efficiency, proven reliability, and scalable performance. With capacities up to 21MW, low-GWP refrigerant, rapid restart capability, and flexible options for heat recovery, free cooling, and thermal energy storage, they provide a sustainable, future-ready foundation for mission-critical chilled-water plants.
- Cooling Capacity: CDHH 900–6000+ tons (up to 21MW)
- Cooling Capacity: CVHH 850–2600 tons (up to 9MW)
- Refrigerant: Low‑GWP R‑1233zd
- Compressor Type: Centrifugal
- Controller: Symbio® 800-Unit Controller
-
Up to 21MW of Cooling with Fewer Chillers Required
Trane CenTraVac® CDHH and CVHH chillers provide 850–6000+ tons of cooling to support hyperscale growth, AI workload swings, and multi‑phase campus buildouts. Their wide operating maps and high‑lift capability deliver stable, efficient chilled‑water cooling for mission‑critical IT environments.
-
Rapid Restart for Uptime-Critical Environments
The CenTraVac® CDHH and CVHH chillers use a direct‑drive centrifugal compressor and low‑pressure R‑1233zd to ensure long‑term reliability. Rapid Restart brings units online in as little as 43 seconds, protecting uptime during power events and ensuring consistent cooling under fast load changes.
-
Wide Operating Map for Modern Cooling Architectures
Among the widest operating maps available for chilled water data-center cooling, CenTraVac® supports CVHH chilled water down to 20°F and lift up to 80°F. That flexibility helps enable air-cooled, liquid-cooled, and hybrid heat-rejection strategies across evolving data-center designs.
-
Low-GWP Efficiency with Lower Impact
Ultra-low-GWP R-1233zd enables high efficiency with minimal environmental impact. On CVHH, economizer technology can improve efficiency by up to 7%, helping reduce plant energy use while supporting sustainability, carbon-reduction, and ESG objectives.
-
Designed for Efficient Redundancy
CenTraVac® chillers support efficient N, N+1, and 2N plant designs with a reduced mechanical-room footprint. High capacity and broad operating flexibility help engineers optimize resilience, scalability, and space utilization across new and retrofit data center applications.
