The Right Balance of Energy Efficiency and Quiet Operation

The ACS model, part of Trane’s Ascend™ line of air-cooled chillers, offers just the right balance of energy efficiency and quiet operation. ACS models, in particular, are optimized for part-load efficiencies, making them ideal for buildings with a large amount of off-peak operation

Choose the sound treatment that’s right for you

ACS chillers offer flexible acoustic options, allowing you to choose the level of sound treatment that best meets application requirements, with packages that offer sound levels as low as 95 dBA at AHRI® conditions for full-load operations. As a result, ACS chillers are especially well-suited for residential or school environments where sound sensitivity is a top priority

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.
