Air-cooled Heat Exchanger Technology

The purpose of this course is to provide an introduction to air-cooled heat exchanger (ACHE) configurations and applications. In this course, we will discuss various ACHE arrangements, construction considerations, fan selection criteria, and methods used to model the thermal and hydraulic performance of an air-cooled heat exchanger.

Suggested Participants

This is an introductory course for engineers – novice to expert – interested in air-cooled heat exchanger construction and performance.
