What Are the Functions of a Water Chiller?

Nov 02, 2014 · What Are the Functions of a Water Chiller? 1. Water chillers circulate as much as 400 tons of water and they can cool water to approximately 20°C (68°F). They are sometimes used as a replacement for an evaporative cooling tower and tend to be cost effective because they cycle water in a circuit rather than requiring a constant flow of city water.
