FAQs About Cooling Towers
Cooling towers remove heat from water through evaporation. As water evaporates, the remaining water cools and is recirculated to absorb more heat from industrial processes or buildings, effectively transferring waste heat into the air. Our line of portable and industrial cooling tower rentals features smaller units like this 300-ton cooling tower that can be positioned via forklift and larger HVAC cooling towers like this 1,000-ton cooling tower. The fleet of HVAC cooling tower rentals includes trusted brands like Evapco, Scott and others.

A chiller cools water, which then cools a building. The chiller transfers the heat to another water loop. This heated water then goes to a cooling tower, where some water evaporates, cooling the remaining water. The cooled water returns to the chiller to repeat the process, keeping the building at a comfortable temperature.
A cooling tower is categorized based on its airflow direction (crossflow or counterflow), draft type (natural, induced, or forced) and assembly method (factory-assembled or field-erected). Crossflow towers have perpendicular air and water flow, while counterflow towers have opposite flow directions. Natural draft towers use convection, while induced and forced draft towers use fans. Smaller towers are usually factory-assembled, while larger ones are field-erected on-site.
Cooling towers and heat exchangers are crucial in industrial processes. Towers cool circulating water, reducing process temperatures through evaporation. Heat exchangers provide extra cooling and recover heat from gas turbine waste gases, ensuring optimal temperatures and improving energy efficiency by utilizing otherwise lost heat.
