Purpose of Seminar:
Whether your chilled water system keeps people or equipment cool, this seminar is for
you if you need to understand how your system works and what you can do to make it
work better.
Having a fundamental understanding of chilled water systems is a prerequisite to being
able to properly maintain them and gain additional efficiency from them. This course
will teach you what you need to know so that you can go back to your workplace and
immediately apply what you have learned.
Who should take this course?
This course is designed for people working on or who are responsible for the chilled
water systems in their facility. Attendees come from a wide variety of industries,
skill-levels, company sizes, and job titles, so if you're not sure you'll fit in or
will benefit from the class, don't worry - you will - as long as you are looking to
increase your knowledge about chillers, cooling towers and other chilled water systems!
