Trane approaches buildings as more than concrete and steel boxes; we see them in terms of the critical comfort needs of the people and the things in the building. More than half of the large buildings in the world today have a Trane chiller at their core, playing a critical role in creating the right comfort environment. Not only do our chillers provide the right temperature, humidity and ventilation, they also help reduce your cost of operation, provide energy efficiency and minimize environmental impact. In fact, Trane EarthWise CenTraVac chiller received the U.S. EPA’s Climate Protection Award as the most energy efficient, lowest emission large chiller available.

The extensive Trane chiller line was developed with decades of know-how and industry leadership and includes centrifugal, rotary and scroll compressor chillers as well as absorption chillers, ranging in nominal capacities from 10 to 3,950 tons. Trane liquid chillers are relied upon for both comfort and process applications excellence 24/7/365 in every corner of the world.

Absorption Liquid Chillers

Absorption chillers use heat to drive the refrigeration cycle, they produce chilled water while consuming just a small amount of electricity to run the pumps on the unit. Absorption chillers generally use steam or hot water to drive the lithium bromide refrigeration cycle but can also use other heat sources.
