An Amazing Combination of High Energy Efficiency and Quiet Operation

The ACR model, part of Trane’s Ascend® line of air-cooled chillers, offers an amazing combination of high energy efficiency and quiet performance. ACR models use advanced technologies like InvisiSound® acoustic-reduction treatments, compressors with variable volume-ratio capability, permanent magnet motors and premium efficiency drives to help achieve low sound levels, maximize efficiency under all operating conditions, lower utility bills and save money.

Specially Designed for Demanding Applications

We designed ACR chillers especially for easy integration with facilities that have specialized requirements. And, an optional harmonic filtration system utilizes a matrix filter design to meet the requirements of IEEE® 519, reducing harmonic distortion to 5 percent or less total demand distortion (TDD). Rapid Restart® features, standard in our air-cooled chiller portfolio, allow the chiller to quickly regain full operational capacity after a power interruption, so mission-critical applications can continue with minimal interruption.

Free Cooling? We’re cool with that.

As a matter of fact, Trane has been integrating free cooling directly into our chillers for a long time. It only makes sense to tap free colder outdoor air to cool the environment inside your building. When you can avoid running the compressor keeping people comfortable is more sustainable, and energy and operating costs are lower. Trane has free cooling chillers covered.


Optimize operations with our advanced controls

Keeping your indoor temperatures in the comfort zone is virtually hands-off with our chiller’s intuitive user interface enabled by our Symbio® 800 controller. Symbio 800 features open standard protocols, enabling seamless and secure integration with any building automation system,  including Trane's Tracer SC+. Depending on your needs, the sysem is capable of connecting via BACnet™ over IP or Air-Fi® wireless (BACnet/Zigbee). Post-installation, connect with our energy analysis and 24/7 monitoring services to assure your chillers are continuously optimized for efficiency and uptime.
