SPX Cooling Technologies, Inc. announces the release of a <a href="http://spxcooling.com/video/crossflow-vs.-counterflow-cooling-towers" target="_blank" rel="noopener">video</a> comparing the two fundamental types of cooling towers – crossflow and counterflow – and the characteristics of each type that may meet requirements for a specific application.

The video utilizes animation to explain how crossflow and counterflow towers are primarily differentiated by the direction of the air movement, and how it interacts with the process water being cooled. In a crossflow tower, air travels horizontally across the direction of the falling water. In a counterflow tower, air travels in the opposite direction, counter to the direction of the falling water. The two types of towers also have different space considerations, maintenance processes and water quality requirements.
The video also explores advantages of crossflow versus counterflow cooling towers. Crossflow cooling towers typically have larger doors for easier access to the tower, variable flow conditions that help the tower perform under cold weather conditions, and integral louvers that help maximize water containment. Counterflow cooling towers offer a smaller footprint, lighter operating weight, and a wider range of heat transfer (fill) media types to address varying sources of cooling water – from clean to dirty.
