An Introduction to Water Cooling Towers

COURSE NO: M02-054
An Introduction to Water Cooling Towers
Course Highlights

This online engineering PDH course provides an introduction to the design, installation and operation of cooling towers. While there are three basic types of cooling water systems: once-through, open recirculating, and closed recirculating cooling water systems, this course describes once-through and open recirculating systems.


Cooling water systems remove heat generated from a variety of industrial processes. Cooling systems that use a water's cooling capacity a single time are called once-through cooling systems. These systems use large volumes of water and typically discharge the once-through water directly to waste. Whereas an open recirculating cooling system uses the same water repeatedly to cool process equipment. Heat absorbed from the process is dissipated to allow reuse of the water.


This 2 PDH online course is intended for mechanical engineers as well as other design and construction professionals interested in learning about the use of cooling towers to provide cooling for HVAC systems and industrial processes.
