10 Leading open circuit cooling tower Suppliers in the world 2025

Dec 22, 2025

Introduction to Open Circuit Cooling Tower

An open - circuit cooling tower is a heat rejection device that operates on the principle of evaporative cooling. It is widely used in various industrial and commercial applications to remove waste heat from processes or equipment. In an open - circuit cooling tower, hot water from the process is distributed over a fill material, which increases the surface area for heat transfer. As air is drawn through the tower, either by natural draft or mechanical fans, a portion of the water evaporates, absorbing latent heat from the remaining water and thus cooling it. The cooled water is then recirculated back to the process. This type of cooling tower is cost - effective, energy - efficient in many cases, and has a relatively simple design, making it a popular choice for industries such as power generation, chemical processing, and HVAC systems.
