Evaporators Designing, Evaluating, and Operating

See upcoming dates

Course Overview

The efficient operation of industrial evaporators requires a working knowledge of the basics of evaporation, heat transfer, and moisture removal. In this course, you will examine how industrial evaporators operate – what they are supposed to do and how they do it. You will learn how to maintain and troubleshoot your existing evaporators and systems and examine how the design of your process impacts the performance and operation of your system. You’ll explore methods to achieve energy savings and improve your product.

Who Should Attend?

This course will benefit:

Engineers, scientists, researchers, and production personnel who are responsible for the design, operation, selection, maintenance or specification of industrial evaporators and evaporation systems in food, chemical, fertilizer, salt, chlor-alkali, and soda ash operations and applications.
