Efficient Data Center Performance in High-Ambient Temperatures
Built for hyperscale and colocation facilities facing rising AI and GPU heat loads, the Trane Ascend ACR air-cooled chiller supports stable cooling performance in demanding environments, with designs rated for ambient temperatures up to 131°F and the ability to stay online providing cooling for short excursions above that.
-
Integrated Free Cooling Lowers Energy Use
A factory-installed waterside economizer helps reduce mechanical cooling hours during favorable ambient conditions, lowering energy use and supporting more efficient operation across seasonal and part-load conditions.
-
Faster Deployment, Lower Site Complexity
The Ascend packaged air-cooled design can reduce onsite installation scope by avoiding cooling towers and condenser water loops, helping simplify project execution for new capacity and phased data center expansion.
In addition, optional integrated free cooling eliminates the need for additional footprint, water connections and electrical connections than using traditional fluid coolers.
-
Reliable Cooling for Mission-Critical Uptime
Multiple compressor circuits, Rapid Restart™, built-in diagnostics, and remote monitoring options help support cooling continuity during load swings, power events, and fault conditions in mission-critical environments.
-
Zero Water Waste Supports ESG Goals
Zero water waste helps data center operators support water stewardship goals while pairing air-cooled chiller operation with low-GWP refrigerant and environmental transparency features such as a published Environmental Product Declaration (EPD).
